McKINNEY — Testimony in a Collin County courtroom Tuesday revealed a 15-year-old boy brought a gun to Wylie East High School to show it off to students in his gym class.
Prosecutors said that teen used the same gun to shoot fellow Wylie East student Nahum Martinez between the eyes. They are in court for a second day, asking a judge to try the suspect as an adult.
The 15-year-old defendant was led into the courtroom in handcuffs and shackles, wearing a blue polo shirt and khaki pants.
The parents of 15-year-old Nahum were asked to leave the courtroom. Prosecutors then showed several graphic photos of the murder victim.
The suspect, whose name is not being reported by WFAA because he is still classified as a juvenile, put his head down and started crying.
Nahum Martinez' mother also shed tears as a Collin County juvenile detention officer testified. The officer described how her son's accused killer laughed when another inmate made a comment that the boy had killed someone.
A Wylie police officer who works at Wylie East High School said the young suspect wrapped up a chrome-plated Remington .45-caliber gun in a T-shirt, put it in a backpack, and brought it to school.
The officer testified that two weeks before the murder, Nahum's girlfriend told him the suspect pulled out the same gun from behind his bed and played with it in front of her and Nahum.
A Wylie detective testified she searched the murder victim's bedroom and found a school assignment where he wrote about being being the victim of bullying. She also found a handwritten note from the suspect to Nahum: "I'm sorry for calling you names. It was just a joke."
The judge's decision whether to try the murder suspect as an adult won't be made for at least 13 days. Testimony in the hearing is scheduled to resume on July 16.
On Monday, other Wylie police officers testified the teenage suspect shot Martinez between the eyes, wrapped the body in a comforter and threw him out a second-floor window. Investigators believe the boy and another teen dragged the body to a nearby storm drain.
One officer who talked with the suspect says the boy finally confessed. Officer Stuart McCoy testified the boy said to him, "I did it. It was my fault. He [Martinez] was playing with the gun. I reached down to grab the gun, and it went off."
If Judge Cyndi Wheless certifies the 15-year-old defendant as an adult, he could face life in prison.
