A South Salt Lake resident fatally shot a 68-year-old man on Friday night in a confrontation in his backyard, police said.

The man was identified as David Antonio Trujillo. South Salt Lake Police Department spokesman Gary Keller said no current address has been found for Trujillo but he did frequent various hotels and motels in the city.

The resident heard a noise outside and when he went to investigate, he was confronted by Trujillo, who was armed with a knife, Keller said.

The confrontation quickly escalated and the suspect was shot and later pronounced dead at the scene, in the area of 3700 South and 200 East, Keller said.

He said dispatchers received 911 calls at about 8:30 p.m., including one from the resident.

The incident is under investigation and the resident is cooperating, according to Keller. He said police have not determined a motive for Trujillo being armed with a knife and in the backyard.

The case will be turned over to the Salt Lake County district attorney's office for screening when the investigation has been completed.

The name of the resident has not been released.
