Answering a knock at the door turned deadly for a south side man overnight, News Radio 1200 WOAI reports

.Police say a group of men were gathered at a home in the 900 block of Grosvenor, which is off Commercial Blvd. about 10:30 Sunday night when they heard somebody knocking at the door.

One of the men got up to answer it, and immediately the other men heard a shot.

They ran into the living room to find a man in his twenties dead on the floor with a gunshot wound to the neck.

Police say the victim was a visitor and did not live at the home, which has detectives wondering whether he was even the intended victim.

Nobody else in the home saw anything, and police have no motive for the shooting and have no suspects.
