On Wednesday, at least 17 people were killed during a shooting at Marjory Stoneman Douglas High School in Parkland, Florida. The suspect, 19-year-old Nikolas Cruz, was arrested at the scene, and, on Thursday morning, he was booked into Broward County Main Jail. Cruz currently faces 17 counts of premeditated murder, and is expected to make his first court appearance sometime on Thursday (though the Miami Herald notes he will be denied bond). Here, everything we know about Cruz so far.

Cruz is a former student who had been expelled from the school.
According to Sheriff Scott Israel of Broward County, Cruz is a former student of Marjory Stoneman Douglas High School. He had previously been expelled for undisclosed disciplinary reasons. One student told the Herald that Cruz had at least partially been kicked out for bringing bullets in his backpack onto the school premises. Cruz was attending another school in Broward County after his expulsion.

He had allegedly been abusive to an ex-girlfriend.
Victoria Olvera, a student at the school, told USA Today that Cruz had ultimately been expelled after a fight with his ex-girlfriend’s new boyfriend. She also said that Cruz had been abusive to his girlfriend.

He had been identified last year as a potential threat to his classmates.
“We were told last year that he wasn’t allowed on campus with a backpack on him,” Cruz’s former math teacher Jim Gard told the Herald. Gard, who was locked in his classroom during the shooting, added, “There were problems with him last year threatening students, and I guess he was asked to leave campus.” However, superintendent Robert Runcie told reporters, “We received no warnings. Potentially there could have been signs out there. But we didn’t have any warning or phone calls or threats that were made.”

Cruz was reportedly obsessed with a female student at the school.
Jim Gard also told the New York Times that several students had alerted him to the fact that Cruz was allegedly obsessed with a female student at the school “to the point of ‘stalking her.’”

Cruz posted images of guns on social media and allegedly wrote threatening comments about wanting to shoot people.
Sheriff Israel has called Cruz’s digital profile “very, very disturbing,” as it contained a number of gun and violence-related posts, according to CNN. Such posts left under the name Nikolas Cruz on YouTube pages and other websites include, “I whana shoot people with my AR-14” [sic], “I am going to kill law enforcement one day they go after the good people,” and “I wanna die Fighting killing shit ton of people.” He also posted pictures on Instagram of himself holding what appears to be a BB gun, as well as an image of a shotgun and others in which he was covering his face and holding long knives.

He purchased the rifle used in the attack legally.
The AR-15 rifle that Cruz allegedly used in the attack was purchased legally. “No laws were violated in the procurement of this weapon,” Peter J. Forcelli of the Bureau of Alcohol, Tobacco, Firearms and Explosives, told the New York Times.

Cruz had been living with the family of a student at the school since his adoptive mom passed away in November.
Cruz’s adoptive mother, Lynda Cruz, died in November from the flu and pneumonia, her cousin Kathie Blaine told CNN. His adoptive father died more than ten years ago from a heart attack. Cruz had been living with a friend’s family since his mother’s death, according to an attorney who represents the family. “They offered him a home and tried to help the kid out because he really didn’t have any other place to stay,” attorney Jim Lewis told WPTV. The family’s son is a student at Marjory Stoneman Douglas High School.

We will update this post as more information becomes available.

The four Nordic combined male athletes from Steamboat had a difficult showing in the first of three events, the individual normal hill/10-kilometer race. Of 48 competitors, Bryan Fletcher was the highest-ranked American, finishing 17th in the first competition of the 2018 Winter Olympics in PyeongChang, while his brother Taylor, Ben Loomis and Jasper Good each struggled, finishing 35th or worse.

Bryan put together an admirable run in the finals of the individual NH/10km event. He jumped a distance of 97.5 meters, which was 14.5m behind the leader — enough to put him at the 18th starting spot for the 10km race. Fletcher did well in the cross-country race, completing the course with a time of 27.03 a time that helped him move up to the 17th position overall in the competition. Although he improved his overall rank Fletcher was nearly two minutes behind a podium position.

After a rather ordinary performance in the first Nordic combined event in PyeongChang, Team USA looks to get back on track in the final two events — the individual large hill/10km race followed by the team large hill/4x5km race.

The good news for the team — specifically the Fletcher brothers — is that their track record suggests signs of improvement. In the 2014 Sochi Games, their worst event was the individual NH/10km. Both were then able to improve their ranks in the individual LH/10km event, as well as complete a finish in the top-six of the team event.

Loomis, 19, and Good, 21, are both in their first ever Olympics. Now with their first event out of the way and those Olympic jitters gone, look for the two young guns to also improve throughout the rest of the 2018 Winter Games.

The individual LH/10km event begins training runs on Feb. 17, with the competition scheduled for Feb. 20. The team event will be held Feb. 22.
