>> growing up we didn't have what you'd say a normal life. i don't know what normal would be though, so i mean i would characterize it as dysfunctional. my dad was an alcoholic. he would rant and rave from the time he got up. on a number of occasions, at least a dozen occasions, my mom would call the hammond police department. >> he was violent? >> oh, yeah. mom would have maybe a black eye, bloody nose, bloody lip. >> he told us his mother wasn't the only target of his father's violence. he was, too. but it wasn't his idea to kill him. >> i was doing some algebra homework, sitting in my room. my sister walked in, made a comment about dad was really screwing her life up, and we had to do something and all this. and i didn't really think she was serious or anything like this, you know. >> his sister, who was nine years older, and her husband, presented a plan. the murder would take place after his father went to bed. >> it was decided, well, okay, we'll go ahead, we'll get some ether, we'll knock him out,
