WEST PAM BEACH, Fla. (AP) - A West Palm Beach man is in custody after authorities say he shot his wife who is being treated with life threatening injuries in a hospital.

According to the Palm Beach County Sheriff's Office, the shooting happened Thursday morning at the couple's suburban home. The man then fled the scene, but his car was spotted near the planetarium and he was arrested without incident.

The woman is being treated at Delray Medical Center. Authorities have not yet identified the couple.

A man killed his estranged wife and four stepchildren on Monday in nearby Riviera Beach before turning the gun on himself. Two people were found dead following another apparent murder-suicide that same day in Broward County.
