A lawyer who stabbed his neighbor to death because he thought the man had molested his 2-year-old daughter was sentenced Friday to 12 years in prison for first-degree manslaughter.

“It’s a Shakespearean tragedy brought into the real world,” Judge Richard Comerford said at the sentencing in Bridgeport, Conn. “Something was set into motion in this man’s mind — real or perceived. It was very real to him.”
