One man died and two teenagers were injured in two separate hit-and-run accidents in Salt Lake City

Police Chief Mike Brown called the accidents “unacceptable” in a press release.

The Salt Lake City Police Department is investigating after two separate hit-and-run accidents killed a man and injured two teenagers.

“I am very concerned about what is happening on our roads,” Police Commissioner Mike Brown said in a press release, calling the accidents “unacceptable.”

Police began investigating the first crash at 1:43 a.m. Sunday, when SLC911 received information about a person lying on the ground at 700 East near 500 South, the release said. The person, a 31-year-old man, died at the scene.

The preliminary investigation shows a dark-colored truck traveling southbound on 700 East struck the man as he was using a crosswalk and then failed to stop, the press release said. Detectives are looking for a small, dark Chevy truck with frontal damage.

Police began investigating the second crash at 4:48 a.m. Sunday, when SLC911 received information about two teenagers lying on the ground at 1300 South and West Temple.

According to the Salt Lake City Fire Department, the injuries the 13- and 14-year-olds sustained are likely to have been hit by a vehicle and towed away.

Paramedics took the youth to a hospital with serious injuries that were not life-threatening. The teenagers were also at a crosswalk when they were hit and were also hit by a dark-colored truck, but police say they don’t believe the two cases are linked.

The accident involving the man on 700 East is the first traffic-related fatality in Salt Lake City this year, the press release said.
