WEST VALLEY CITY, Utah >> A 16-year-old boy shot five people in a confrontation between two groups at a carnival in a Salt Lake City suburb Sunday, killing three of them including an 8-month-old infant, police said.

Police working at WestFest at Centennial Park, about 6 miles southwest of downtown Salt Lake City, saw the two groups Sunday night.

“As they approached to break up the altercation, a 16-year-old male from one of the groups pulled out a gun and fired,” the department posted on X. One officer fired back but did not hit anyone.

The shooter struck and killed an 18-year-old man in one of the groups, police said. Besides the infant, a 41-year-old woman bystander also was killed.
