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.
The Associated Press withheld the name of the boy because of his age. He was being held at a juvenile detention center on suspicion of homicide. Formal charges have not been filed.
