She told the Daily News: 'As soon as they married, he turned on her. The real Cedric came out. He told her he would throw her out the window. She was shocked, like "What happened?" He was so kind to her while they were dating. She had no idea.'

Mrs Sykes claimed Anderson had been a pastor for 17 years and her daughter had taught at a Sunday School.

She added: 'She was a wonderful, God-fearing woman. But the bible says, "Thou shalt not kill." So I can imagine where he is now.'

Mrs Sykes said his daughter knew Anderson for about four years before they got married.

She said: 'She thought she had a wonderful husband, but she found out he was not wonderful at all.'

She told the LA Times: 'He had other motives. She left him and that's where the trouble began. She broke up with him and he came out with a different personality. She decided she needed to leave him.'

Martinez and another nine-year-old student were taken to the hospital via helicopter in critical condition. It was announced at a press conference on Monday afternoon that Martinez died of his injuries at the hospital. The other child, whose identity was not revealed, is in stable condition.

Anderson was allowed entry to the school after signing in at the front desk and telling them that he had something to drop off for his wife. They were estranged and had only been married for a few months before the separation.

Anderson has several past charges on his record, including domestic violence, weapons and drug-related charges, according to police. It is not known if he was convicted of these charges.

According to Anderson's Facebook page, the couple tied the knot in late January of this year. They had been separated for the past month to a month and a half, according to police. It is not known what sparked their separation.

Anderson had several photos of him and Smith following their wedding ceremony, including videos of them kissing while hiking in Sedona, Arizona for their honeymoon and a post calling her an angel.

The husband posted a video in February saying Smith was 'making me really happy.' In the 12-second clip, he also said, 'She knows when to ignore me' as he laughed and flashed a smile.

He added: 'That makes a happy marriage.'

According to the police and their Facebook profiles, they both had children but it is not yet known if they had the children together.

San Bernardino Police Chief Jarrod Burguan said: 'Cedric entered the classroom and — from what we understand, without saying anything — armed with a large caliber revolver, opened fire on his wife. She was killed in that exchange.'

On Monday evening, the Riverside home Anderson and Smith shared during their brief marriage was cordoned off with police tape.

The home, inside an upmarket gated community, belonged to Smith - who had previously lived in the property with her ex-husband Roderic, 53.

For Elizabeth Barajas it had been an hours-long nightmare waiting to learn the fate of the daughter she had dropped off at school a couple of hours before police reported gunfire in a classroom that left two adults and one child dead and another child wounded.

Then, in some ways, the nightmare became worse.

Barajas learned her daughter, Marissa Perez, had been sitting at her desk Monday morning when a gunman stormed into her classroom, shot her teacher to death, killed one of her classmates and wounded another before killing himself.

'I don't know what to do. I don't know what to tell her,' Barajas said as the two held each other and sobbed after the ordeal that sent police flooding onto the campus of San Bernardino's North Park School.

As Marissa and about 600 other students were shepherded to safety, Barajas and hundreds of other parents raced to the school. There they would endure an agonizing four-hour wait before learning that all but two of their children were physically if not emotionally unharmed.

'She just said she was scared. As soon as she saw the guy with the gun, she went under the table. She keeps telling me `My teacher got shot, my friend got shot,' Barajas said as she clutched her daughter's blood-stained sweatshirt.

Marissa said the shooter didn't say a word as he opened fire. One of her friends was hit, she added, as she pointed to her abdomen.

Amberly Raffle, who had left her son with his pre-kindergarten class earlier that morning, said she wasn't sure what the sirens were about until her sister-in-law ran to her house to tell her there was a problem at the school.

'Policemen were everywhere and ambulances, firetrucks, helicopters,' she said of the scene she saw. 'I got really scared then.'

It was 'every parent's worst nightmare,' said Holly Penalber as she wiped tears from her face while waiting to hear the fate of her 9-year-old son and 7-year-old daughter.

Penalber, a Riverside County sheriff's deputy, was on a training assignment when she began getting frantic texts from her husband and mother, saying something bad had happened at the school.

Then she waited hours outside a nearby high school where parents were eventually reunited with their children. She was too nervous to join Barajas and others in the library, saying there were more rumors than information there. But eventually she heard from someone who had seen her children and assured her they were safe.

'It was such a sigh of relief. But I won't feel good until I hold my kids,' she said.

One of the first parents to be reunited with a child was Raffle, who cried tears of joys as she embraced her son.

'He doesn't really know what happened,' she said. 'I think we're blessed because of that.'

Barajas is concerned about what witnessing the shooting will do to her daughter.

'They can't just tell us your kids are fine,' she said. 'Obviously my kid is not fine. She witnessed what happened to her teacher and the other students, and all they said is your kids are safe, your kids are fine.'

San Bernardino Police confirmed at a press conference that the shooter signed in at the front desk and was known to other staff who did not know he was carrying a gun when he was allowed entry.

From the front desk, he walked to the female teacher's classroom where he opened fire.

'The entire incident is limited to a single classroom. The suspect had come to visit the female victim,' Captain Ron Maas of the San Bernardino Police Department said.

'The children, we do not believe were targeted. (They were) the unfortunate recipients of injuries by being in proximity to the female at the time.'

Police do not yet know how many shots exactly were fired in total. All of the 520 other children in the school were immediately evacuated afterwards.

They were seen making their way across the playground holding hands before being put on buses to leave the scene.

DRAMATIC MOMENT POLICE ARRIVE AT SAN BERNARDINO ELEMENTARY SCHOOL – MOMENTS AFTER TEACHER WAS SHOT DEAD BY HER HUSBAND By: Ruth Styles in SAN BERNARDINO, CA. for DailyMail.com This is the dramatic moment police arrived at North Park Elementary School in San Bernardino, California – moments after a teacher was shot dead by her husband. Footage obtained exclusively by DailyMail.com also shows first responders desperately trying to save the life of one of the two students gunned down alongside her – one of whom has now died. Jonathan Martinez, eight, passed away earlier this afternoon in hospital, while his teacher, Karen Smith, 53, died at the scene. Police have now confirmed that the gunman was her husband, Cedric Anderson, who also perished as the result of a self-inflicted gunshot wound. Anderson, of Riverside, California, is thought to have murdered his special needs teacher wife as a result of a domestic dispute according to police. Authorities say Martinez was standing behind Smith when Anderson opened fire, along with another boy. The second student, who has not been named, is now in a stable condition at the nearby Loma Linda hospital, according to police. The shooting began at 10.35am local time, with Anderson signed in by staff at the front office after telling them he needed to drop something off for his estranged wife. Moments later, Anderson opened fire – murdering his wife of just months and Martinez in front of 14 other children. The shooter, who has a history of domestic violence and drug charges according to police, then killed himself. Neighbors told DailyMail.com that they did not hear the gunshots but saw police arriving less than five minutes after the shooting occurred. Jacob Pardo, 28, whose home overlooks the school, said: 'There were at least 30 cop cars and then a bunch of undercover police officers came down. 'I saw them escorting the students to the back of the school – a lot of them had been playing outside when it happened.' He added: It was just crazy. There was a helicopter going round overhead and then we saw it land and take one of the students away. Most of the students were evacuated to nearby Cajon High School where parents endured a five-hour wait before being allowed to take their children home. Helen Galegos, 60, told DailyMail.com that her grandson Mars, eight, was among the students rescued by police and said she was forced to wait five hours before being allowed to take him home. She said: 'I just got him right now. About five hours. They were saying they had to hold the kids because they wanted to check each kid didn't have a mark and if they did, they had to talk to them.' Mars, who witnessed part of the shooting, was among the children spoken to by police and, said his grandmother, knew Smith. 'To know that my grandson had to see some of this? Yeah, he's joking right now but later on, this is going to affect him,' said Gallegos. 'It's going to affect all of us – every single one of us. 'No he does not understand. He's been talking to a bunch of students, a bunch of teachers, police officers asked him a lot of questions, so he's riled up. 'He did get to see the blood. He did know who the teacher was – he would see her all the time.' Paying tribute to Smith, she added: 'I've met her quite a few times, she's a great teacher. They're all good teachers. 'The school is a good place for kids. It's just, why did it happen? There was somebody coming into the school - you would think they would be prepared so nobody got hurt.' On Monday evening, the Riverside home Anderson and Smith shared during their brief marriage was cordoned off with police tape. The home, inside an upmarket gated community, belonged to Smith - who had previously lived in the property with her ex-husband Roderic, 53. As DailyMail.com watched, a crime scene investigation team were seen arriving at the house carrying cameras and forensic equipment.
