PHOENIX (3TV/CBS 5) — A man faces a manslaughter charge after accidentally shooting and killing his 18-year-old friend in Maryvale on Sunday night. Police said Sergio Lopez-Ruiz, 18, and his friend, Brian Lujan, were handling Lopez-Ruiz’s gun when it went off and hit Lujan. Court paperwork obtained Tuesday revealed that Lopez-Ruiz told investigators he didn’t know how the weapon became loaded because he had removed the magazine beforehand.

Police say it happened at a home near 71st Avenue and Thomas Road around 6:30 p.m. when someone reported that their son’s friend was “shot.” When officers showed up, they found Lujan with a gunshot wound. He was taken to the hospital, where he later died. Court paperwork says Lopez-Ruiz told police he brought a loaded gun to his friend’s house, having it by his side on the couch in the bedroom. Lujan was sitting across from Lopez-Ruiz when Lopez-Ruiz removed the magazine and pointed it toward Lujan before handing it over to Lujan.

Court documents say that Lopez-Ruiz told investigators that he did not have his finger on the trigger when the gun was fired, but that both had a hand on the gun. However, he admitted that he did not pull back the slide to check if the chamber had already been loaded before handing it over.

Records also showed the gun had been stolen from Houston, Texas, investigators said. Lopez-Ruiz, however, told police that he bought it from a pawn shop and claimed he had the original bill of sale. Lopez-Ruiz was booked into jail on manslaughter charges, and his bond is set at $20,000.
