A Detroit police sergeant whose wife was shot to death in a suspected contract killing has been found hanged in a suburban park.
Police tell the Detroit Free Press that 38-year-old Sgt. David Cobb was found dead Friday night in Sterling Heights, a city 15 miles north of downtown Detroit.
Cobb's 47-year-old wife, Rose, was fatally shot Dec. 26 in a parking lot on Detroit's east side. In April, police arrested 27-year-old Vincent Smothers, who told police Cobb hired him to kill his wife.
Smothers claimed Cobb was having an affair and wanted his wife's life insurance money. He is awaiting trial for murder.
Cobb was arrested a day after Smothers. He was released after prosecutors said there wasn't enough evidence to charge him.
