Police say a 16-year-old who was on a weekend pass from a children's home has fatally shot a 17-year-old boy and critically wounded his own 17-year-old sister after finding them together.

Police say the shooting happened about 1 a.m. Sunday. Police Sgt. Jesse Boomer says officers responded to the home after getting a report of shots fired.

Boomer says the boy was dead and the girl was taken to a hospital, where she was in critical condition.

He says the 16-year-old was upset that his sister was having relations with the male victim.

Police say the shooter was out on a weekend pass from the Wichita Children's Home, an emergency, temporary shelter for abused and neglected teens and runaways. The suspect was arrested late Sunday.
