SCOTTSBLUFF, Neb. (AP) — A Nebraska man on death row for raping and killing a teenage Gering newspaper carrier is seeking a new trial for a separate conviction of raping a different paper carrier.

35-year-old Jeffrey Hessler has filed a motion for post-conviction relief, saying his defense attorney was ineffective and that he was too mentally ill to know what he was doing when he pleaded no contest in 2004 to raping a 15-year-old newspaper carrier in 2002.

Inmates typically file post-conviction relief motions after they have exhausted all other appeals.

Hessler was also convicted in 2004 of kidnapping, raping and killing 15-year-old newspaper carrier Heather Guerrero in 2003. He was sentenced to death.

A hearing on his latest motion has been set for Feb. 23.
