Sheriff's officials say a 2-month-old boy has died after he stopped breathing on a United Airlines flight that made an emergency landing in Milwaukee.

Milwaukee County sheriff's Sgt. Philip Wentzel said Thursday the infant was with his parents on a flight from Detroit to Denver Wednesday afternoon when he stopped breathing. Wentzel says a passenger trained in CPR tried to revive the child. Once on the ground at General Mitchell International Airport in Milwaukee, paramedics also tried to revive the baby, but were unsuccessful.

Wentzel says the family is from South Dakota. He says there are no signs of foul play.
