A man was shot and killed in front of his south Fulton County home Monday, and police hope a person seen walking in the area around the time of the deadly shooting can help them solve the case.

The man, identified Tuesday by the Fulton County Medical Examiner’s office as 58-year-old Soloman Williams, was found outside his Gossamer Street home in Union City’s Oakley Township subdivision, police said.

Authorities released grainy surveillance video showing someone walking in the area around the time of the shooting. Fulton police want to talk to that person.

Anyone with information about the shooting is asked to call 911.
