For his part, Carruthers, 49, of Sandusky, is on the road to recovery at Mercy St. Vincent Medical Center in Toledo.
Police said there's a "person of interest," but refused to elaborate.
Carruthers was shot three times at about 6:12 p.m. at a self-serve car wash in the 500 block of W. Perkins Ave. He suffered at least one gunshot wound to the chest, police said.
Perkins police Chief Ken Klamar, who at the time was off duty and loading groceries into his car at a nearby store, called 911 after he heard three gunshots.
About nine minutes later an employee at Firelands Counseling and Recovery Center, in the 1900 block of Hayes Ave., called 911 after Carruthers came stumbling into the office.
