Condemned inmate Lester Bower Jr. is asking the U.S. Supreme Court to keep him from becoming the oldest Texas prisoner put to death.

The 67-year-old Bower is facing lethal injection Wednesday for the October 1983 fatal shootings of four men at an airplane hangar on a ranch near Sherman, about 60 miles north of Dallas.

He'd be the eighth inmate executed this year in Texas, which carries out capital punishment more than any other state.

Bower always has maintained his innocence, although he initially lied to investigators who used telephone records to identify his involvement related to the sale of an ultralight aircraft owned by one of the victims.

Prosecutors convinced a jury to send him to death row by building a circumstantial case that he stole the aircraft.
