UPDATE: Student Killed, Suspect Arrested Following Shooting at Arlington Lamar High School

Editor's note, 3/20/23, 2:22 p.m.: This story has been updated with new information throughout.

A juvenile male suspect is being charged with capital murder after police say he shot and killed a student outside of Lamar High School in Arlington on Monday morning.

During a Monday afternoon press conference, Arlington Chief of Police Alexander Jones declined to name the suspect or the victim, but said the suspect is being held at the Tarrant County Juvenile Detention Center. Jones did confirm that the suspect and the victim were both students at Lamar High School. Another student injured during the shooting was grazed by shrapnel and is now recovering.

Jones said police are still investigating to determine the motive. The police chief also said the weapon has been recovered and that video of the incident does exist and is being scrutinized.

"I'm still numb, but I'm thankful more kids weren't hurt," Lamar Principal Andrew Hagman said during the press conference, held outside on the campus of the high school.

The Arlington Police Department tweeted at 7:41 a.m. on Monday, “This morning, we responded to Lamar High School to investigate a reported shooting that took place outside the school building. The scene is secure and the suspected shooter is in custody.”

NBC 5 reported that "Jesse Minton, with the Arlington Police Department, said one of the injured students was a juvenile male who was critically injured and was taken to an area hospital by ground ambulance. The other injured student, Minton said, was a juvenile female who suffered injuries that were not life-threatening after either being grazed by a bullet or hit by flying debris."

The report also noted "there are two full-time Arlington police officers assigned to the campus as school resource officers and that they were able to immediately aid in the response."

Details provided by Arlington police via Twitter at 9:48 a.m. state, "At around 6:55 this morning, APD responded to the Lamar HS campus after we received multiple reports of shots fired outside the school building."

The police also say that school was not in session at the time of the shooting, and they believe the shooter did not enter the building. The shooter was taken into custody by police "shortly after arriving on scene," said APD.

Arlington police announced at 10:41 a.m. that the school lockdown had been lifted. Students were then bused to the designated reunification center at Arlington ISD Athletic Center on Division Street, where parents and guardians began picking up students at noon.

Arlington ISD Superintendent Dr. Marcelo Cavazos said there will be no school tomorrow, and beginning on Wednesday, counselors will be made available to all Lamar students for as long as is necessary.
