 Michael was told by Rex Balsom that the baby was really the missing son of Todd Manning.When Dr. Spencer Truman is murdered, Rex, who ran into Michael at the hospital on the night of Spencer Truman's murder, believed Michael was the one who stabbed Spencer to prevent him from revealing the paternity of Tommy to Todd Manning (Spencer had kidnapped Tommy, who was really the child of Todd Manning and Margaret Cochran on the day of his birth); Michael believed Rex had committed the murder for the same reason.However, after John had Rex and Michael held overnight in a holding cell for questioning because he believed they were hiding something and wondered what the two could possibly be keeping secret between them, they talked it out and discovered that neither of them had killed Truman.
