WATERBURY, Conn. (AP) — A reopened police investigation has concluded that actor Dylan McDermott's mother was killed in 1967 by her now-dead gangster boyfriend.

Waterbury police reopened the investigation last year into Diane McDermott's death after Dylan McDermott contacted them with questions, the Republican-American newspaper reported (http://bit.ly/KX4WBx ) Sunday and Monday as part of a two-part series.

He was 5 years old when his mother was shot in February 1967. Her death was originally ruled an accident.
