Police kill Riverton man who held a knife to his mother’s throat. It’s the sixth officer shooting in less than two weeks.

A man reportedly holding a knife to the throat of his mother was shot and killed by police in Riverton on Monday morning.

Two officers responded to a report of domestic violence at 11779 S. Stone Ridge Court at about 6:40 a.m., according to Salt Lake County Sheriff Rosie Rivera, when Jason Robert Whittle, 26, threatened his mother with a knife.

At 6:50 a.m., “They took some action. Shots were fired. And we do know that the male is deceased,” Rivera said.

Whittle’s 56-year-old mother was unharmed; no police officers were injured. The shooting took place outside the home where Whittle’s mother lives.

As per protocol, an outside agency — in this case, the Salt Lake City Police Department — is investigating the shooting. Any witnesses are asked to contact Salt Lake police.

Monday’s shooting was the sixth police shooting in 13 days. “It has been a tough couple of weeks,” Rivera said.
