Utah Teen Arrested in Deaths of Younger Brothers

Two boys were killed with a knife

WEST POINT, Utah –  A teenager was arrested Thursday in the deaths of his two younger brothers, ages 4 and 10, at the family home in a Utah subdivision of new houses and tidy lawns, police said.

Authorities believe the boys died from knife wounds and that the 15-year-old boy acted alone in what appeared to be an unplanned attack, Davis County Sheriff Todd Richardson said.

"As result of the emerging details, the 15-year-old juvenile has officially been taken into custody," Richardson said.
