At least four people were injured in a school shooting Wednesday at Timberview High School in Arlington, Texas. The suspect is in custody and is being questioned by investigators, police said.
Here’s what we know so far:
What led up to the shooting?
At around 9:15 a.m. local time, the Arlington Police Department responded to reports of shots fired inside the school.
While it is unclear what directly led to the shooting, police say there was a confrontation beforehand.
“The incident occurred in a classroom on the second floor of the school,” Arlington police said in a statement. “Investigators believe a physical fight broke out just prior to the shooting.”
The shooting was not a random act of violence and was committed by a student who was in a fight and drew a weapon, assistant police chief Kevin Kolbye said.
After the shooting, responding officers determined that the suspect left the school, and “there was no longer an active threat inside the building,” police said.
What do we know about the victims?
The shooting left four people injured. Among the four, two were shot and three were hospitalized.
All three hospitalized are expected to survive, Kolbye said.
One of the victims is a 15-year-old boy with gunshot wounds who is listed in critical condition, according to the Arlington police statement. A 25-year-old man also had gunshot wounds and is in good condition, the release said. A teenage girl who may have been grazed by a bullet was released Wednesday night and is in good condition with an abrasion, said Arlington Police spokesman Tim Ciesco.
Officials said about 1,700 students were at the school.
“Once security sweeps of the school were complete, all remaining students at Timberview High School were safely evacuated and bussed to an off-site reunification center where they were released to their families,” Arlington police said.
What do we know about the suspect?
Timothy George Simpkins will be charged with three counts of aggravated assault with a deadly weapon, according to the police.
Simpkins, 18, turned himself in without incident Wednesday afternoon, police said, and his bond was set at $75,000. He was released from jail Thursday, a family spokesperson said, and online jail records show he is no longer listed as an inmate at the Tarrant County Jail.
A weapon was recovered in “the streets of Grand Prairie,” a city a few miles from the high school, Arlington police said.
Grand Prairie police said the weapon recovered was a .45-caliber handgun. Police believe it was the weapon used in the school shooting, according to Grand Prairie police Chief Daniel Scesney, but that has not been confirmed. He said the gun has been turned over to the ATF for ballistics testing.
Simpkins’ family is asking for forgiveness, according to a family spokesperson who spoke to CNN affiliate WFAA.
“The decision that he made taking the gun, we’re not justifying that. That was not right, but he was trying to protect himself,” family spokesperson Carol Harrison-Lafayette said.
