Texas has joined Idaho in using a single drug to execute a death row inmate.
A man convicted of killing a stockbroker following a carjacking was put to death by the State of Texas Wednesday, using a strong dose of Pentobarbital.
On June 12, Richard Leavitt was executed at the Idaho State Correction Institution, also using 2.5 grams of Pentobarbital, which first shut down his respiration, knocking him unconscious and ultimately causing respiratory collapse. Cardiac arrest and death soon followed.
Texas is considered the nation's most-active capital punishment state and has turned to the single drug protocol because the state's supply of a drug used previously in a three-drug method, pancuronium bromide, is in short supply.
Yokamon Hearn, 33, became the sixth Texas prisoner executed this year and the 483rd since 1982. At least eight other Texas prisoners have scheduled execution dates in the coming months, including three in August.
