A central New York man has been sentenced to 22 years to life in prison for a deadly stabbing he says was prompted by a pornographic video.

Randy Green said he was "not a bad person" as he was sentenced Thursday for slitting Ray Pike's throat Aug. 15 on a trail in Gloversville.

Green says he was psychologically affected by seeing the sexually explicit video, which he says depicted Pike with a young girl. Pike was a convicted sex offender who volunteered at local churches.

Defense lawyer Robert Abdella says a third man may have shown Green the video specifically to enrage him.

Fulton County District Attorney Louise Sira says police never found the tape.

Pike's daughter, Melissa Richardson, calls Green a "merciless and cowardly murderer who took it upon himself to play executioner."
