The family of San Bernardino gunman Syed Farook have claimed that he had been teased by colleagues about his long Islamic beard hours after it emerged that he had also clashed with a Jewish co-worker over religion weeks before he and his wife killed 14 at a holiday party.

While the exact motive for the massacre remains unclear, lawyers for the Farook family said the gunman had been subject to a series of disparaging comments about his traditional Muslim appearance.

But they insisted that the health inspector had ‘brushed off’ the remarks and they remained at a loss to explain why he mercilessly gunned down 14 people and wounded 21, the majority his former co-workers, on Wednesday.

Their comments came hours after it emerged that Farook had recently got into a heated argument with colleague Nicholas Thalasinos, a Messianic Jew, who was named as one of his victims.

Thalasinos, a county restaurant inspector, was said to regularly discuss politics and religion with Farook.

Colleague Kuuleme Stephen said that when she had called Thalasinos at work he told her he was having a heated discussion with Farook about Islam who had told him Islam was a peaceful religion and that Americans do not understand Islam.

Thalasinos was known to be passionate about pro-Israel causes and regularly ranted about Islam on Facebook.

On September 11th, 2013, alongside a photo of a shirtless victim plummeting to his death from the burning World Trade Center, Mr Thalasinos posted: 'On behalf of this guy… You can stick your Million Muslim March up your asses'.

In one of his final status updates on Tuesday, Thalasinos responded to an anti-Semitic tirade allegedly penned by an apparent Muslim living in Ukraine, who railed against Jews and Israel.

‘Anyway my new hobby appears to be BLOCKING PAGAN ANTISEMITIC TROGLODYTES so I'm just passing this along to warn others,’ was Thalasinos' reply.

Again, it is unclear if the dispute played a part in the massacre.

David Chesley, an attorney acting for Farook's family,is questioning accounts of the shootings and whether information released by the police and FBI was accurate.

To illustrate his point, he made a bizarre reference to the Sandy Hook massacre, suggesting it didn't take place as described in the official narrative.

'There have been suggestions that it may be something that was related to their work, that somehow he was a disgruntled employee,' he said.

'But it doesn't seem plausible to us that this petite woman would be involved in this sort of hyper-caricatured, Bonnie and Clyde crazy scenario.

'There was a lot of questions drawn with Sandy Hook and whether or not that was a real incident or not.

'But I mean obviously these things were found there, how they got there we don't know.'

Asked if he doubted if the Dec 2012 Sandy Hook massacre, which claimed 26 lives, took place, Mr Chesley added: 'There has been a lot speculation about it is all I would say.

Farook's brother, Syed Raheel Farook (pictured right, leaving his sister's house), served in the Navy from 2003 to 2007. He was attached to the crew of the aircraft carrier USS Enterprise, serving as an information systems technician

'There's a lot of people that said it happened but hasn't happened in the way that it was purported to have taken place.

'There's no question that incidents have taken place and evidence was found but we just question some of that.'

The family’s lawyers also revealed for the first time that Farook's mother Rafia, 62, was held for questioning in the wake of the mass shooting after cops pulled her over in one of her other son's SUVs.

She was released without charge the next day but the vehicle is still in the hands of law enforcement officials, they said.

The Farook family, including his father Syed, 66, older brother Syed Raheel, and sisters Eba, 24, Saira, 32, and her husband Farhan Khan, 41, spent several hours talking to FBI agents on Thursday.

Speaking outside Mr Khan's house late last night, attorney Chesley insisted that Farook's relatives had no idea he was plotting a massacre or stockpiling weapons with his wife Tashfeen Malik, 27.

FBI agents discovered a huge arsenal – including nearly 5,000 rounds of ammunition, a dozen pipe bombs and hundreds of tools for making IEDs at the couple’s home.

It also emerged that Farook was in touch by phone and through social media with more than one international terrorism subject. Meanwhile, Farook's older brother, Syed Raheel Farook, was revealed a decorated Navy veteran honored for his role in the war on terror

But Mr Chesley said there was 'no smoking gun' to suggest a motive but added: 'Both the sisters and the brothers as they went through the information today, there was one silly thing that came up - that some of his co-workers at some point made remarks about his beard.

'But it so slight and no-one has ever stated that he has ever acted in a hostile or a violent way towards anyone. They were a very polite, conservative married couple.'

His colleague and fellow attorney, Mohammad Abuershaid, added: 'There is no indication that he was involved with anybody physically.

‘All we know is that there was a couple of situations with people who might have teased him about his facial hair.

'There's no indication he had a short temper. It was people just teasing him about his facial hair and how he looked. He had a long beard and a very short trimmed haircut.

'It was just basic comments but he used to brush them off pretty easily. The family is in shock just as we are. They had no idea something like this would happen.'

On Wednesday morning, Farook and Malik dropped off their six-month-old baby with Farook's mother, according to KTLA, saying they were going to a doctor's appointment.

Both lawyers refused to comment on the dead couple's child other to say she was safe and being cared for. They said the family last saw Farook on Sunday for a family meal.

The coupled lived in a rented apartment in Redlands, a 15-minute drive from San Bernardino, with their mother Rafia.

The couple were armed with a .223-caliber DPMS Model A15 rifle, a Smith and Wesson M&P15 rifle as well as Llama handgun and a Smith and Wesson handgun (pictured)

Mr Chesley said that it was 'important that Muslims should not be intimidated or harassed' because of the shooting because there was no evidence as yet to say Farook's religion fueled the killings.

Referencing the recent shooting at a Planned Parenthood clinic in Colorado Springs by white 57-year-old Robert Lewis Dear, Mr Chesley said: 'Those are the acts of mad people, they don't represent a religion'. He added: ‘It's important for everyone to know that the family was as surprised as anyone.

‘When they got the news they were scared that their brother was basically in danger because they were so shocked and clueless about what was taking place. 'They could not imagine their own brother as having done anything like this.'

Farook and Malik fired as many as 75 rounds inside a conference center at the Inland Regional Center during a holiday party for county health employees on Wednesday morning, killing 14 and injuring a further 21.

The couple came dressed in black tactical-style vests and armed with a .223-caliber DPMS Model A15 rifle, a Smith and Wesson M&P15 rifle, a handgun made by Llama and a Smith and Wesson handgun.

They also each wore a GoPro camera as they went on their rampage, police said.

Federal officials said all four weapons were purchased legally in the United States four years ago - the handguns by Farook himself and the assault rifles by a third party.

A federal law enforcement source told the LA Times Farook and Malik bought the guns at Annie's Get Your Gun, a firearms store in the city of Corona that bills itself as a 'family-friendly gun store.' A person who identified themselves as the owner denied that the store sold the weapons to the shooters.

An additional 1,400 rifle rounds were found inside the bullet-riddled vehicle the pair used to evade police on Wednesday. Police also recovered more than 2,000 handgun bullets

During a standoff with police in Redlands five hours after the San Bernardino massacre, the husband and wife unleashed a barrage of bullets on the responding cops, who returned fire, peppering the couple's rental Ford Expedition SUV with 380 rounds. Both Farook and Malik were pronounced dead at the scene.

When law enforcement officials searched the bullet-riddled vehicle with Utah license plates, they found more than 1,600 rounds of ammunition on or around the deceased shooters.

During a press conference this evening, the first police officer at the scene, San Bernardino Police Lt Mike Madden, a 24-year veteran, described the ‘unspeakable carnage’ he witnessed inside the conference room amid Christmas trees and decorated tables.– and his horror at seeing the ‘pure panic’ on the faces of the wounded.

Describing the situation as ‘surreal’, Lt. Madden said that he and other officers were forced to pass people who were injured in a bid to stop the attack.

‘This is a tragedy I have never experienced in my career – but everyone who responded knew their job was to bring calm to chaos.’

He added: ‘It was unspeakable the carnage we were seeing and the fear and panic on people's faces.’

San Bernardino Police Chief Jarrod Burguan said that 91 guests had been invited to the county health department’s holiday luncheon – but there were between 75 and 80 people present when the suspects opened fire.

He confirmed that 12 of the 14 dead were San Bernardino county employees. Of the 21 injured, he said 18 were county employees.

During an early-morning search of a residence in the city of Redlands associated with Farook or his family, Chief Burguan said agents came away with a massive arsenal of ammunition, including 2,000 9mm rounds, another 2,500 .223 rounds and several hundred long-rifle bullets, along with 12 pipe bombs and tools that could be used to construct IEDs.

Burguan noted that the couple were well-equipped to carry out another attack. He added that Farook had no criminal record that police were aware of.

It also emerged that the suspects attempted smashed their cell phones and tried to destroy their hard drives in a bid to cover their tracks.

The suspects have apparently attempted to destroy all devices with digital memory, including phones and hard drives, law enforcement sources told ABC News.

FBI computer forensics analysts will try to extract what they can, but sources told the station that the work will be 'painstaking'.

By early Thursday afternoon, the first of the victims of the San Bernardino massacre were identified as three health department workers.

Damian Meins, 58; Nicholas Thalasinos, 52; and Michael Wetzel, 37, were among the 14 shot dead inside at the Inland Regional Center on Wednesday.

Thalasinos's wife, Jennifer, told the New York Times her husband was a co-worker of Farook's at the health department and the two appeared friendly.

Meins had only been working at the San Bernardino County of Environmental Health Department for three months when he was shot dead. He leaves behind a wife, high-school sweetheart Trenna Meins, and two children, according to the Press Enterprise.

THE VICTIMS On Thursday, San Bernardino County sheriff's department released the full list of the 14 people who died. They are: Bennetta Bet-Badal, 46, Rialto Aurora Godoy, 26, San Jacinto Isaac Amanios, 60, Fontana Larry Kaufman, 42, Rialto Harry Bowman, 46, Upland Yvette Velasco, 27, Fontana Sierra Clayborn, 27, Moreno Valley Robert Adams, 40, Yucaipa Nicholas Thalasinos, 52, Colton Tin Nguyen, 31, Santa Ana Juan Espinoza, 50, Highland Damian Meins, 58, Riverside Shannon Johnson, 45, Los Angeles Michael Wetzel, 37, Lake Arrowhead Advertisement

Wetzel also worked as an environmental health specialist with San Bernardino County. The 37-year-old leaves behind a wife, Renee, and six children.

Friends and family have identified two more victims: county health department employ Sierra Clayborn and Larry Kaufman, 42, who ran a coffee shop at the Inland Regional Center.

On Thursday afternoon, a hospital official told reporters outside the Loma Linda Medical Center that two wounded people remain in a critical condition. Two others are in a fair condition and one is due to be released today.

Those who knew Farook, among them his colleagues at the San Bernardino County Public Health Department, described him as a devout Muslim but not someone who often talked about religion.

'He never struck me as a fanatic, he never struck me as suspicious,' said Griselda Reisinger, a former colleague.

Members of two local mosques where Farook worshipped sounded a similar note Thursday, telling NBC News they knew him as a mild-mannered, peaceful and highly devout man.

They also insisted that if he had indeed been radicalized, it did not happen at their mosques.

‘We never saw him raise his voice. We never saw him curse at anyone, disrespect anyone. He was always a very nice guy, always very simple, very straightforward,’ Nizaam Ali, of Dar-Al-Uloom Al-Islamiyah mosque in San Bernardino told the station.

Ali and his brother, Rahemaan, said Farook was a devout Muslim who showed up to pray every day but abruptly stopped three weeks ago.

They said that Farook had been a constant presence at the mosque for two years and had recently memorized the Quran.

Ali confirmed that in 2013, Farook traveled to Saudi Arabia on hajj - a religious pilgrimage that every adult Muslim must go on at least once - and to meet his fiancee, Tashfeen Malik, whom he intended to marry in the holiest shrine of Islam, the Black Stone in Mecca's Grand Mosque.

When he returned to the States, he approached Mustafa Kuko, the director of the Islamic Center of Riverside where Farook had been a member for several years, asking him to host a wedding celebration there.

Co-worker Patrick Baccari, who shared a cubicle with Farook, told the Los Angeles Times he and his young family appeared to be 'living the American dream.'

President Barack Obama addressed the shooting from the Oval Office shortly before noon Eastern Time, saying it is possible the massacre in San Bernardino was related to terrorism, but it's also possible it was workplace-related, or that the perpetrators had mixed motives.

'At this stage, we don't yet know why this terrible event occurred,' a somber Mr Obama told the press.

'We do know that the two individuals who were killed were equipped with weapons and appeared to have access to additional weaponry at their homes, but we don't know why they did it; we do not know the extent of their plans and their motivations.'

The commander-in-chief assured Americans that the FBI, who has taken over the investigation, will get to the bottom of what happened in California on Wednesday.

In his remarks, Obama also touched upon the issue of gun control, saying the nation must make it harder for people to carry out acts of violence.

'We see the prevalence of these kinds of mass shootings in this country, and like so many Americans, sometime feel as if there is nothing we can do about it,’ Obama said.

'We can't just leave it to our professionals to deal with the problem of these kinds of horrible killings. We all have a part to play.

'We're gonna have to search ourselves, as a society, to make sure that we can take basic steps that would make it harder, not impossible, but harder, for individuals to get access to weapons.'

Earlier in the day, US Attorney General Loretta Lynch said at a press conference the Justice Department will be offering ‘any and all assistance necessary’ as the investigation into the California mass shooting continues.

Lynch was speaking at an event about criminal justice at the White House. She called Wednesday’s deadly massacre ‘unspeakable.’

Lynch says the government doesn't know a lot yet about the incident. But she says the FBI, the U.S. Marshals Service and other federal authorities have been dispatched.

The attorney general said that whatever the results of the investigation, there's no place for this type of violence in the US.

In the hours after the shooting, more information emerged about Farook, who was born in the US, and Malik, whom he met in Saudi Arabia.

Farook's family was originally from Pakistan, but he was born in Illinois, while Malik was born in Pakistan and had lived in Saudi Arabia before coming to the United States, said Hussam Ayloush, executive director of the Council on American-Islamic Relations (CAIR). Farook had an older brother, he added, who had served in the US military.

NPR reported that Farook's brother, Syed Raheel Farook, served in the Navy from 2003 to 2007. He was attached to the crew of the aircraft carrier USS Enterprise, serving as an information systems technician, and made at least one deployment to the Middle East.

Farook graduated from California State University, San Bernardino with a degree in environmental health in 2010, according to the university's commencement document. He later enrolled in a graduate program at the school but reportedly dropped out last year.

As BuzzFeed first reported, according to Transparent California, which publishes public employee salary information, Farook earned $51,747 plus benefits, in 2013 working as an environmental health specialist.

According to Farook’s brother-in-law, Farhan Khan, he and Malik met on a dating website two years ago. The California health inspector then traveled to Saudi Arabia in 2013 to meet Malik’s family, and again in July 2014 to marry her.

FBI Assistant Director David Bowdich said Farook brought his newlywed wife over to the US on a 90-day K-1 fiancee visa. CBS News reported that Malik passed DHS counterterrorism screening as part of her vetting.

The couple applied on September 30, 2014, for a permanent resident green card for Malik, which requires passing criminal and national security background checks. She was granted a conditional green card in July 2015.

In an online profile reportedly created by Farook and his parents six years ago on the dating site iMilap.com, a 'one stop source for Indian matrimonial and dating services,' the health inspector described himself as 6 feet tall and said he didn't drink or smoke, according toABC News.

Farook wrote that he was part of a 'religios [sic] but modern family of 4 - 2 girls, 2 boys,' and that he enjoyed 'doing target practice with younger sister and friends' in their backyard.

He added that he enjoyed working on vintage and modern cars, and read religious books while enjoying eating out sometimes.

He was also registered on Dubaimatrimonial.com, a dating site that is the 'first and only legal marriage service provider in UAE' (United Arab Emirates), according to the website description. In that profile, Farook described himself as being from Karachi, Pakistan, but was born in Chicago and was residing in Los Angles as an American citizen. His religion was shown as Islam.

He also shared his thoughts on living a balanced life as a Muslim-American: 'I try to live as a good Muslim. Looking for a girl who has the same outlook, wear hijab, but live the life to the fullest.'

Public records suggest possible turbulence in Farook's younger life.

In 2006, Rafia Farook, who records indicate is Farook's mother, filed in a Riverside court for divorce from her husband, the elder Mr Farook.

She enumerated multiple instances of domestic abuse in the legal filing, and said her husband 'threatens to kill himself on a daily basis.' During one incident, she said in a court filing, her son came between them 'to save me.'

The suspect's co-worker, Patrick Baccari, said Farook was gone for about a month in the spring. A short time after his return, he was joined by his wife, a woman he described as a pharmacist. A baby soon followed.

An online baby registry on the site The Bump that has been attributed to Tashfeen Malik by NBC News mentions the city of Riverside, California, as the mother's address and a due date of May 17, 2015. Malik's short wish list included Pampers diapers for newborns, cotton swabs, baby body wash and a convertible car seat.

Baccari said the reserved Farook showed no signs of unusual behavior, although he grew out his beard several months ago.

He said he had been sitting at the same table as Farook at the party on Wednesday morning, but his co-worker suddenly disappeared, leaving his coat behind. Baccari escaped most of the carnage as he was in the bathroom when the shooting started, and sustained only minor wounds from shrapnel which made it through the wall.

'If I hadn't been in the bathroom, I'd probably be laying dead on the floor,' he said.

San Bernardino Police Chief Jarrod Burguan said that Farook was 'angry' when he left the party, before returning with Malik and a stash of heavy weapons. Burguan said that there was obviously 'some degree of planning involved' in the attack.

Survivors of the shooting said the heavily armed duo entered the party venue and opened fire on the guests without uttering a single word.

Police said a third person was detained, but during Thursday morning's press conference Chief Burguan said that individual played no part in the shooting and is not considered a suspect or a person of interest.

Burguan elaborated saying that police realized the person was wanted on a misdemeanor warrant and he was booked on that warrant.

Dramatic aerial images showed the aftermath of the police chase, which came to an end around a mile and a half from the scene of the massacre.

The bodies of Farook and Malik can be seen near their shot-out SUV, surrounded by heavily-armed officers. One of them was killed in the passenger seat and later removed from the vehicle, while another of the pair appears to have bolted from the vehicle and been gunned down not far away.

Fragments of video from witnesses on the ground showed the killers and officers exchanging gunfire on the roads of San Bernardino as bystanders ducked for cover. The chase ended some time between 3pm and 4pm local time Wednesday - as long as five hours after the massacre began.

A source told CNN that the suspects threw pipe bombs out of the windows of the vehicle before the shootout with police.

A spokesman for the Bureau of Alcohol, Tobacco, Firearms and Explosives said the suspects threw a thick-gauge copper pipe out of the SUV, but no explosives were found inside. The fake pipe bomb was equipped with a piece of material made to look like a wick.

One officer was hit in the shoot-out, and was taken to hospital with non-life-threatening injuries.

The married couple also reportedly had left explosives behind in the conference center in San Bernardino prior their escape in the wake of the slaughter.

A bag believed to belong to Farook and Malik was later found at the site of the holiday party. Inside, police discovered three crudely made bombs packed with black powder and rigged to a remote-controlled toy car.

The remote for the car was later recovered from Farook and Malik's SUV, a law enforcement official said, adding that its presence indicated that the couple planned to detonate the explosives from a distance but something must have stopped them.

REVEALED: ARMORY OF HUSBAND-AND-WIFE KILLER DUO WHO USED 'MILITARY TACTICS' IN POLICE SHOOTOUT Police revealed late Wednesday that Farook and Malik were armed with two assault rifles and two automatic handguns in their battle to the death with the cops. Officials told the LA Times that a .223-caliber DPMS Model A15 rifle and a Smith and Wesson M&P15 rifle were both recovered from the scene. They also found a handgun made by Llama and a Smith and Wesson handgun. The Bureau of Alcohol, Tobacco and Firearms said they traced the guns and found that all of them were bought legally - the handguns by Farooks himself and the assault rifles by a third party. It came as a police source speaking to Fox News said the killer duo used 'military tactics' to confront police. They reportedly had body-mounted cameras, which would have allowed them to record the massacre. Advertisement
