Update: In what was probably Cruz's last meal as a free man, the high school shooter - who had repeatedly threatened to shoot up Stoneman Douglas High School in Parkland, Fla. before following through yesterday - told police that he stopped at a Subway and McDonald's after committing the mass murder, but before he was arrested, per the New York Post.

Cruz, 19, fled the school by dropping his weapon and blending in with other students before ducking into a Walmart, before heading to the Subway to purchase a drink and then entered a McDonald's at 3:01 pm and sat in the restaurant for a period of time before taking off on foot.

At 3:41 pm Cruz was taken into custody by a local police officer without incident. The information was revealed as part of a timeline of events.

Around the time he was ordered held without bond during his first court appearance after murdering 17 of his former classmates and wounding nearly two dozen others, Florida high school shooter Nikolas Cruz was linked by the Anti-Defamation League to a White Supremacist group called the "Republic of Florida" ABC reported, although the report was subsequently challenged.

On Thursday afternoon, Cruz made his first court appearance, "shackled and cowering in fear" as the Mail described it. He was wearing an orange jumpsuit and both his hands and ankles were bound.

At that point, Nikolas Cruz confessed to being the shooter at Marjory Stoneman Douglas High School, a Broward County Sheriff’s Office report said.

According to the report, he told interrogating officers that he “began shooting students that he saw in the hallways and on school grounds” on Wednesday afternoon.

The report adds that Cruz told officers he “brought additional loaded magazines to the school campus and kept them hidden in a backpack until he got on campus to begin his assault.”

Cruz told investigators that as students began to flee, he decided to discard his AR-15 rifle and a vest he was wearing so he could blend in with the crowd. Police recovered the rifle and the vest. The police report adds that Cruz purchased the rifle in February 2017, but does not say where it was purchased.

An attorney for the 19-year-old killer said her client is "sad and remorseful."

Public defender Melisa McNeill told reporters Thursday that Nikolas Cruz is fully aware of what’s going on but he’s also just a “broken human being.” McNeill spoke after a judge ordered Cruz held without bond. She had her arm around Cruz during the brief hearing. She became emotional while speaking to reporters, saying she’s fully aware of the impact the shooting has had on the community.

Earlier, the ADL said Republic of Florida leader Jordan Jereb said that Cruz was associated with his group. Jereb, who is based in Tallahassee, said Cruz was brought into the group by another member and had participated in one or more ROF training exercises in the Tallahassee area, the ADL said.

Law enforcement officials haven't confirmed the connection, and while Jereb did publicly disavow Cruz and his actions, he confirmed that Cruz did train with his militia, according to the New York Post. The leader of the group also told ABC News he has not spoken to Cruz in “some time” but said "he knew he would be getting this call." He would not comment further but emphasized that his group was not a terrorist organization.

However, a law enforcement official told the AP he knows of “no known ties” between the suspect and a white supremacist group. Lt. Grady Jordan is a spokesman for the Leon County Sheriff’s Office in Tallahassee, where the white nationalist militia known as the Republic of Florida is based. Jordan said Thursday that his office has arrested militia leader Jordan Jereb at least four times since January 2014 and has been monitoring the group’s membership.

He says his office has “very solid” information on the group and “there’s no known ties that we have that we can connect” 19-year-old Nikolas Cruz with the group.

Jereb told The Associated Press earlier Thursday that Cruz was a member and participated in paramilitary drills in Tallahassee. Jereb said he didn’t know Cruz personally and that “he acted on his own behalf of what he just did and he’s solely responsible for what he just did.”

The Tallahassee Democrat reported that Jereb is a "self-described right-wing extremist nut," who faced charges in 2016 after threatening a high-ranking staff member of Gov. Rick Scott's office, and who is "known to ride a bike through neighborhoods wearing paramilitary garb and stand at the side of the road with an R.O.F flag. He has filmed numerous run-ins with law enforcement in Tallahassee in which he consistently tells officers when he is stopped, "I'm a free man traveling the land."

As we reported earlier, Cruz, a 19-year-old orphan with a troubled past, a fascination with weapons and resistance groups, and an AR-15 rifle, was charged with 17 counts of premeditated murder Thursday morning after being questioned for hours by state and federal authorities following the deadliest school shooting in the US in five years.

Cruz's unsuspecting former classmates thought they were having another drill Wednesday afternoon when a fire alarm sounded, requiring them to file out of their classrooms. That's when Cruz, equipped with a gas mask, smoke grenades and multiple magazines of ammunition, opened fire with a semi-automatic weapon, killing 17 people and sending hundreds of students fleeing into the streets. Cruz was able to leave the scene and blend in, but was apprehended about an hour after he stopped firing.

The ROF has mostly young members in north and south Florida and calls itself a "white civil rights organization fighting for white identitarian politics” while seeking to build a “white ethnostate” in Florida.

Three former schoolmates of Cruz told ABC News that Cruz was part of the group. They claimed he marched with the group frequently and was often seen with Jereb, who also confirmed to ABC News that Cruz was, at least at one point, part of that group.

In an interview with ABC News’ George Stephanopoulos, an attorney for the family that had taken Cruz in for the past few months said Cruz was “depressed” following his mother’s death but he had been going to therapy.

The family is still “shocked,” he said, that Cruz would allegedly engage in mass violence.

“They indicated they saw nothing like this coming,” Lewis said. “They never saw any anger, no bad feelings about the school.”

A family that had taken Cruz in after the November death of his mother was aware he owned a legally purchased AR-15 within the past year from a federally licensed dealer, but they said it was locked in a safe.

“He brought it into the home and it was in a locked gun safe,” the lawyer said. “That was the condition when he came into their home that the gun was locked away.”

Cruz had a history of mental illness and violent threats that had led to him getting in trouble repeatedly at school. One student who participated in Junior ROTC with Cruz described him as a “psycho.” Cruz was a well-known weapons enthusiast, the student said, who once tried to sell knives to a classmate.

Cruz even reportedly threatened to shoot up the school...

"About a year ago I saw him upset in the morning," student Brent Black told ABC News. "And I was like, 'yo what’s wrong with you?' And he was like 'umm, don’t know.' And I was like 'what’s up with you?' He's like 'I swear to God I'll shoot up this school.' And then I was like 'watch what you’re saying around me,' and then I just left him after that. He came up to me later on the day and apologized for what he said."

But despite these threats, no action was taken other than to bar him from campus and to instruct teachers not to let him near campus with a backpack. Broward County Sheriff also said "disturbing" content was found on Cruz's social media accounts. The photos released so far depict Cruz with an arsenal of weapons - a common sign among school shooters. the Columbine shooters also took photos of them posing with weapons.

In a shocking admission, an FBI official also said Thursday that they were warned - not once, but twice - about the shooter. One of the warnings came in September, from a bail bondsman in Mississippi who alerted the feds about an alarming online message Cruz wrote saying he was 'going to be a professional school shooter'.

Ben Bennight, a Youtube commentator, said he alerted the FBI to a comment shared by Cruz on one of his YouTube videos back in September. He says the FBI was quick to respond to the concerning statement, arriving at his office the very next day to find out if he knew anything about Cruz, but the bureau was ultimately unable to ascertain his identity.

Even the president lamented the lack of action despite so many "disturbing signs"...

So many signs that the Florida shooter was mentally disturbed, even expelled from school for bad and erratic behavior. Neighbors and classmates knew he was a big problem. Must always report such instances to authorities, again and again! — Donald J. Trump (@realDonaldTrump) February 15, 2018

Police say they're "already dissecting" his social media posts.

“We have already begun to dissect his websites and things on social media that he was on, and some of the things that have come to mind are very, very disturbing,” Israel said.

A cowering Cruz was decided to be held without bail during his first court appearance on Thursday, where he was officially charged with 17 counts of premeditated murder.

The 19-year-old who killed 17 and injured more than a dozen in a shooting at Marjory Stoneman Douglas High School in Parkland, Florida on Wednesday did not speak in court today, other than to confirm his name with a polite 'yes ma'am' to the judge. Mostly, he he kept his gaze to the ground.

He wore an orange jumpsuit, and had both his hands and ankles shackled. As he took the podium to speak to the judge over livestream video from the Broward County jail, a handful of sheriff's deputies and prison officials gathered around, as the Daily Mail reported.

A female attorney representing Cruz rested a reassuring hand on his shoulder while the charges were read.

A Broward County official said Cruz has been on suicide watch since being taken into custody because he has threatened to kill himself.

He was initially taken to the hospital for "labored breathing"...police then spent most of the night questioning Cruz about his motives and the possible role of anybody else.

The shooting was the 30th mass shooting in the US this year, and both Connecticut senators Chris Murphy and Richard Blumenthal released videos of them making strident calls for gun control.

Florida Gov. Rick Scott speaks to reporters at a Thursday morning press conference about the shooter, accompanied by Broward County Sheriff Scott Israel and Parkland School Superintendent Robert Runcie.

In another admission that calls into question how, exactly, Cruz managed to legally buy an assault rifle, Broward County Mayor Beam Furr also revealed that Cruz had been getting treatment at a mental health clinic for a while, but hadn't been back to the clinic in more than a year.

"It wasn’t like there wasn’t concern for him," Furr told CNN. "We try to keep our eyes out on those kids who aren’t connected. … In this case we didn’t find a way to connect with this kid."

President Trump addressed the nation this morning after the shooting, which was the eighth largest mass shooting in US history.

Cruz had been suspended from the school from fighting his ex girlfriend's new boyfriend and was depressed and having girl problems at the time of the shooting.

Trump ordered all flags to fly at half-mast Thursday...

Meanwhile, the Mail has published a detailed list of all the alleged "warning signs" about Cruz and his intentions that were simply missed or ignored...
