HUNTSVILLE, Texas - Texas has executed its first prisoner under a lethal injection procedure that uses one drug instead of three.
Yokamon Hearn was sentenced to death in the 1998 carjacking and slaying of a suburban Dallas stockbroker. The 33-year-old Hearn's execution Wednesday was the state's first using a single dose of the sedative pentobarbital.
Texas prison officials last week announced they were modifying the three-drug method they've used since 1982.
Hearn's execution came about 3½ hours after the U.S. Supreme Court refused appeals from his attorneys.
Hearn was convicted in the killing of 23-year-old Frank Meziere, who was slain after being abducted from a Dallas car wash.
Hearn showed no apparent unusual reaction to the drug as his execution began. He was pronounced dead at 6:37 p.m.
