WASHINGTON (AP) — The White House says a botched execution of a death row inmate in Oklahoma fell short of the humane standards required when the death penalty is carried out.
Officials halted Clayton Lockett's execution Tuesday when he convulsed violently and tried to lift his head after a doctor declared him unconscious. He later died of an apparent heart attack.

White House spokesman Jay Carney says President Barack Obama believes evidence shows the death penalty doesn't effectively deter crime. But he says Obama believes some crimes are so heinous that the death penalty is merited. He says the crimes in Lockett's case are indisputably heinous.
But Carney says the U.S. has a fundamental standard that the death penalty must be carried out humanely. He says everyone would recognize that this case fell short.

Lethal Injection

Until 2010, most states used a three-drug combination: an anesthetic (pentobarbital or sodium thiopental), a paralytic agent (pancuronium bromide) to paralyze the muscle system, and a drug to stop the heart (potassium chloride). Recently, European pharmaceutical companies have refused to sell drugs to the U.S. for use in lethal injections, requiring states to find new, untested alternatives.
Gas Chamber

Gas chambers, like this one pictured at the former Missouri State Penitentiary in Jefferson City, Mo., were first used in the U.S. in 1924. In the procedure, an inmate is sealed inside an airtight chamber which is then filled with toxic hydrogen cyanide gas. Oxygen starvation ultimately leads to death, but the inmate does not immediately lose consciousness.
Electric Chair

The first electric chair was used in 1890. Electrodes attached to an inmate's body deliver a current of electricity. Sometimes more than one jolt is required.

Hanging

Hanging was used as the primary method of execution in the U.S. until the electric chair's invention in 1890. Death is typically caused by dislocation of the vertebrae or asphyxiation, but in cases when the rope is too long, the inmate can sometimes be decapitated. If too short, the inmate can take up to 45 minutes to die.

This Old West-style execution method dates back to the invention of firearms. In a typical scenario in the U.S., the inmate is strapped to a chair. Five anonymous marksmen stand 20 feet away, aim rifles at the convict's heart, and shoot. One rifle is loaded with blanks.
