TEXARKANA, Texas (KTAL/KMSS) – A 17-year-old is dead and two other teenagers are in police custody after a fatal shooting in Texarkana, Texas Monday that police say stemmed from a fight at Texas High School earlier in the day.

The shooting happened early Monday afternoon on Sidney Drive. Police were called to the scene around 2 p.m. and arrived to find Ulises Martinez lying in the street, already dead from a gunshot wound to the chest. The shooting forced the temporary lockdown of a nearby middle school.

Police say several other teenagers were involved in the fight. Kamorian and Kieran Meachem, along with others, were interviewed by detectives at the police department and taken into custody.

The brothers are booked in the Bi-State Jail on murder charges with a $1 million bond for both. Police are investigating to determine which brother pulled the trigger.

Texarkana Independent School District officials said in a statement released Tuesday that both students attended Texas High School and confirmed the shooting was a continuation of a verbal argument between Martinez and 18-year-old Kamorian Meachem that had been addressed by school staff earlier in the day.

“Through our internal investigation of this incident, we do not see any potential threats or danger to the school or students. However, out of an abundance of caution, our plan of action for the remainder of the week is to have increased security presence on campus and to make counseling available to our students and staff,” said Chief Communications Officer Tina Veal-Gooch.

A GoFundMe was set up by Ulises’s brother, Junior, to help the family cover funeral costs. He says they lost his sister Jessica three months prior to this and asks that everyone keep his family in their prayers.
