An off-duty Jefferson County (KY) Sheriff's Deputy was shot and killed Thursday morning while working as security at a Shively car lot.

Louisville Metro Police say 26-year-old Brandon Shirley was shot inside his personal truck at Rockford Lane Auto Sales. Officers say someone walked up and shot at him, Lex18 reports.

"We can say, with a feeling of confidence, that he was targeted... and that he was ambushed," said Louisville Metro Police Department chief Erika Shields. "We will make an arrest."

Shirley had to be rushed to the University of Louisville Hospital. He later died from his injuries.

JCSO Sheriff John Aubrey told WLKY that Shirley joined the department working at the courthouse in March 2019. He graduated from the police academy that December.

No arrests have been made. Investigators say there may be possible suspects.
