William Evans, 62, and his wife Brenda Evans were found fatally stabbed inside their Lenox Street home on Detroit’s east side on Mother’s Day, May 13, 2012. The Wayne County Medical Examiner ruled both deaths homicides. The scene showed a violent struggle; the house had been ransacked but cash and jewelry were reportedly left behind. The couple’s daughter says William had recently won a lottery prize and believes a winning ticket was taken, a theory family members say explains why the pair were targeted.

Investigators examined several possible leads early on, including a suggestion the home was linked to drug activity, which the family strongly denies. No arrests or publicly identified suspects have been announced and the case has gone cold, leaving many unanswered questions about motive and opportunity.

If anyone knew the Evanses, saw suspicious activity in that neighborhood around May 13, 2012, or has information about a stolen lottery ticket, please come forward.
