LIVINGSTON, Texas (AP) – Sixty-seven-year-old Lester Bower will be the oldest Texas inmate executed if his scheduled lethal injection is carried out this week in Huntsville for the slayings of four men at a North Texas ranch more than 31 years ago.

Bower insists he didn’t kill the four at a ranch hangar where he says he bought an ultralight airplane in October 1983. Grayson County prosecutors who said he stole the plane built a circumstantial case against the former chemical salesman from Arlington. Bower lied to investigators when his name showed up in the phone records of one of the victims.

Bower’s attorneys have appeals before the U.S. Supreme Court to try to block Wednesday evening’s punishment. The justices rejected another appeal in March.

State attorneys say 30 years of litigation is enough.
