The Kentucky police department still mourning the ambush slaying of one of its officers has received a threat warning that more officers will be killed.
Bardstown Police Chief Rick McCubbin said Tuesday his department received a recent letter threatening that "there are more to come."
McCubbin says that was a reference to the ambush of Bardstown Officer Jason Ellis last month.
The chief says the threat was turned over to Kentucky State Police and the FBI.
Ellis - a K-9 officer - was hit with shotgun blasts after he got out of his cruiser to pick up tree limbs strewn on a highway exit ramp in Nelson County.
McCubbin has said he thinks Ellis was targeted in the slaying.
McCubbin says Bardstown police officers won't retreat from doing their job.
