LIVINGSTON, Texas (AP) — Attorneys have made a rare clemency request for one of Texas’ longest-serving death row inmates, saying he should be freed before inoperable liver cancer soon takes his life.

Max Soffar, 58, has been on death row more than 33 years for a 1980 robbery at a Houston bowling alley where three people were shot and killed and a fourth was maimed. Soffar and his lawyers long have maintained that he’s innocent, although he has been tried, convicted and condemned twice, most recently in 2006.
