Otisville — Family members of a 27-year-old Wayne State University student who disappeared a month ago after stepping outside of a bar in a small Michigan town are seeking clues about his whereabouts.

Ken Gruno had a credit card with him, but he left his coat behind when he went outside the Otisville Hotel Bar in Otisville, 70 miles north of Detroit, in the early hours of Dec. 27. He was visiting with high school friends at the bar.

Dianna Gruno tells The Flint Journal there's no known reason why her son left. Kelsea Etson, Gruno's wife, has also asked anyone with information to come forward.

Organized searches haven't been successful. State police Detective Sgt. David Van Singel, who is heading the investigation, says there's no indication of foul play.
