SALT LAKE CITY (ABC4 News) – Salt Lake County District Attorney’s Office ruled an October 2018 officer-involved shooting legally justified.
Salt Lake County District Attorney Sim Gill walked members of the media through the findings of the investigation Thursday afternoon.
A West Jordan Police Department officer shot and killed Diamonte Reynolds Riviore on October 11, 2018, following a domestic disturbance at his girlfriend’s apartment.
The DA’s Office determined the officer believed “deadly force was necessary to defend himself and/or the other officers on the scene.”
Three officers responded to the apartment because of a 911 which reported that Riviore was holding his girlfriend at knifepoint.
When officers responded to the residence, a woman eventually opened the door carrying a baby. She told the officers that Riviore was in the “back” of the apartment.
“Each officer later indicated they almost immediately saw the Mr. Riviore was holding a knife while standing just inside the bathroom door,” read the DA’s report.
Investigators said once officers entered in the bedroom, multiple commands were shouted at Riviore to drop the knife and to show his open or empty hands.
“Mr. Rivioire, after physically threatening his girlfriend and seeking refuge in her bathroom once officers arrived, repeatedly opened the door and made stabbing motions toward the officers with a knife,” the report continued.
Two of the officers attempted to deployed Tasers, but they were unsuccessful. The officer who fired the fatal shots testified “as Mr. Riviore was starting to advance out with the knife up in his hand, that’s when I came up from my low ready and I fire two rounds at him” and “[a]t the point, I felt if, if I don’t’ engage the threat, I feared he was going to stab and kill myself or [the other two officers].”
The DA’s office said the officer’s account of what happened is supported and corroborated by body camera footage. The recordings also show Riviore’s repeated stabbing motions toward the officers with a knife were in extremely close quarters where all three officers were apparently within a few feet of the knife.
