Kentucky State Police say the fatal shooting of a police officer was premeditated and are asking for the public's help in finding suspects.

Authorities held a press conference Sunday to provide more details about the early Saturday morning shooting of 33-year-old Bardstown Officer Jason Ellis.

State Police spokesman Norman Chaffins told The Associated Press that Ellis was shot multiple times with a shotgun after he got out of his cruiser to pick up debris on Bluegrass Parkway in Nelson County. Ellis was in uniform and was driving home.

Chaffins said investigators determined the shooting was an ambush. He said anyone that may have seen something suspicious in the days leading up to the shooting is asked to contact Kentucky State Police.

A reward is now up to $6,000.
