Police officers responding to a 911 call made a gruesome discovery in Alabama early Sunday: the bodies of five people, all shot to death.

FOX News Radio's Chris Hoenig has the story:

Birmingham Police got a call about a possible robbery in a home during the early morning hours Sunday.

(Williams) "They responded here to the incident location.  They located five persons inside who were deceased on the scene."

...Birmingham Police Sgt. Johnny Williams.  All five victims were shot execution-style.  Police say they believe the murders were not a random act of violence and that more than one person was involved in the crime.

Neighbors say the people who lived in the house moved in just over a year ago, calling them cordial people who kept to themselves.
