LANCASTER  (AP) — A man has been arrested on suspicion of killing his brother’s friend with a bow and arrow during a dispute at his Southern California home.

Los Angeles County Sheriff’s authorities say 23-year-old Garrett Adams was taken into custody at his Lancaster home early Saturday after the victim was fatally struck in the upper torso.

Investigators believe the victim was trying to break up an argument between Adams and his girlfriend when Adams shot him. He was pronounced dead at a hospital.

Adams’ brother, who was friends with the victim, also tried to intervene in the dispute. He was not injured.

Adams was booked for investigation of murder and held on $1 million bail.
