thought that would be what ended the pain and the problems that she caused. one morning, i woke up about 4:00 in the morning and drove to where they was living, my stepmother and my dad, and rang the doorbell. and when she answered the doorbell, i shot her at point-blank range. and then my dad -- my dad come around the corner on me, and i shot him three times. i've always regretted shooting my dad because i felt like i was close to my dad. it almost killed me, you know? my stepsister called the police on me and i surrendered to the police that morning. i felt like i was at the end of my rope and i did what i did. >> our crew first met steven parker more than a year earlier during our shooting of the original "lockup: holman." he was in ad-seg back then and considered very dangerous. >> steven parker is crazy. he's not a person that's very intelligent. >> it wouldn't take much to incite a riot or whatever. you know. you could take four officers hostage at the same time and it's going to domino. it's going to domino.
