A 16-year-old boy shot five people in a confrontation between two groups at a carnival in a Salt Lake City suburb, killing three of them including an 8-month-old infant, police said.
The shooting Sunday in West Valley City happened a day after an apparently unrelated shooting killed a man at a ''No Kings'' protest and marked an unusually violent weekend in the Salt Lake City area.
Police working at WestFest at Centennial Park, about 6 miles (10 kilometers) southwest of downtown Salt Lake City, saw the two groups begin arguing Sunday night just 100 yards (91 meters) from a police mobile command post.
''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 Hassan Lugundi, 18, of West Valley City, in one of the groups. Lugundi appeared to have been an intended target, police said.
Besides the infant boy, whose identity was not released, bystander Fnu Reena, 41, of West Jordan, Utah, was killed. Both died at a hospital.
Reena was not the infant's mother, though she was in roughly the same line of fire.
Two other teens, a 17-year-old girl and a 15-year-old boy, had non-life-threatening wounds in the arm, police said.
