Multiple people were shot Saturday along a highway near the southeastern Kentucky city of London in what was described as an active shooter situation, authorities said. A search is underway for the gunman. 

The Laurel County Sheriff’s Office reported that “numerous people were shot” and Interstate 75 was closed about nine miles north of London. 

The sheriff’s office said it was searching for a person of interest in the shooting described as 32-year-old Joseph A. Couch. He was described as a White man, about 5-foot-10 and weighing 154 pounds. A photo of Couch was also released.  

Trooper Scottie Pennington, a Kentucky State Police spokesperson, urged residents in the area to stay inside. Louisville ATF agents wrote on social media they are responding and assisting state and local police with a “critical incident” near Interstate 75.

No further details were immediately provided. The number of victims and their conditions was still unclear. 

“Kentucky, we are aware of a shooting on I-75 in Laurel County,” Kentucky Gov. Andy Beshear wrote in a social media post. “Law enforcement has shut the interstate down in both directions at exit 49. Please avoid the area. We will provide more details once they are available.”

This is a developing story and will be updated.
