CINCINNATI -- The FBI announced Monday it is offering a $50,000 reward for information in the death of Bardstown, Kentucky officer Jason Ellis.
The FBI is offering the reward for information leading to the identification, arrest and conviction of the person or group responsible for Ellis' death.
Ellis was killed in an ambush on May 25. Ellis was shot after he got out of his cruiser to pick up tree limbs strewn on a highway exit ramp.
Bardstown Police Chief Rick McCubbin has said he thinks Ellis was targeted in the slaying.
"Officer Ellis was gunned down in what appears to be a carefully planned ambush," the FBI said in a release.
In June, Kentucky State Police said divers searched a pond near where Ellis was gunned down, but no evidence was found.
Ellis is survived by his wife and two young sons.
The FBI, together with the Kentucky State Police, ask that anyone with information about this case call the FBI at 502-263-6000 or the Kentucky State Police at 270-766-5078.
