Prosecutors charged a Colorado man, accused of shooting two teenage boys stealing his car on Thursday, with murder after one of the teenagers died.

Orest Schur, 27, is charged with one count of first-degree murder and another count of attempted first-degree murder following the fatal shooting of 14-year-old Xavier Kirk and the non-fatal shooting of a 13-year-old in Aurora, Colorado, police told USA TODAY.

Residents heard a car alarm going off Wednesday night and saw two people dressed in black trying to break into a Hyundai Elantra before Schur confronted them, Aurora Police wrote on their website. The two teens later sped away in a different vehicle.

According to the press release, Schur drove his Hyundai to follow the teenagers before they crashed a short distance away in a neighborhood block. Schur then fired several shots at the boys he suspected of trying to break into his car, police said.

“A car alarm going off is what attracted the attention of some of the residents of the area. So, we received multiple 911 calls,” Officer Joe Moylan said. “He basically told us that he was involved in a shooting, that he was heading home and that’s where we met him.”

Moylan said he could not comment on what he told officers when they arrived at the scene.

An ambulance took Kirk to a local hospital where he died due to his wounds. The 13-year-old boy went to a nearby relative’s home and was taken to a hospital for treatment soon after. He is expected to survive.
