Investigators have released photos they believe might help them find a Goose Creek murder suspect.

One photo, taken in a North Charleston Wal-Mart, shows a woman believed to be one of the last people to have seen William Kuhn, a 40-year-old convenience store clerk, before he was shot to death last month in Dogwood Park in Goose Creek. Another photo shows a dark-colored sedan believed to be her car.

Stephon Johnson, 24, has been charged with murdering Kuhn. He remains at large and is believed to moving around the Goose Creek and North Charleston areas.

Anyone with information about the woman or Johnson is asked to call Investigator Paul Tremblay at the Goose Creek Police Department at 863-5200, ext. 2463, or leave an anonymous tip at Crime Stoppers at 554-1111.
