Connecticut State Police are investigating an attempted robbery in Prospect that left one person dead on Friday night.

Troopers were dispatched to Route 69 Auto Sales shortly before 7 p.m. after getting a report of an attempted robbery.

Police said two men entered the store and began assaulting at least three people inside. During that time, one of the victims, who police said is a legal permit holder in Connecticut, fired at least one shot and both suspects fled on foot.

According to police, one of the suspects was struck by at least one bullet and was found dead behind the store. The second suspect is still at large.

"At this time, we're asking members of the public to stay vigilant, keep their doors and windows locked. If they see anyhting out of the ordinary, any person out of the ordinary in their neighborhoods, we ask them to contact Troop I or contact 911 to report this behavior," police said.

Members of the Central District Major Crimes Division are canvassing the area to try and find video footage.

The victims were transported to the hospital to be treated for non life-threatening injuries.
