INNOCENCE EXECUTED

One of the strongest arguments against the death penalty is the frightening chance of executing an innocent person. Columbia University law professor James Liebman said he and a team of students have proven that Texas gave a lethal injection to the wrong man.

Carlos De Luna was executed in 1989 for stabbing to death a gas station clerk in Corpus Christi six years earlier. It was a ghastly crime. The trial attracted local attention, but not from concern that a guiltless man would be punished while the killer went free.

De Luna, an eighth grade dropout, maintained that he was innocent from the moment cops put him in the back seat of a patrol car until the day he died. Today, 29 years after De Luna was arrested, Liebman and his team published a mammoth report in the Human Rights Law Review that concludes De Luna paid with his life for a crime he likely did not commit. Shoddy police work, the prosecution's failure to pursue another suspect, and a weak defense combined to send De Luna to death row, they argued.

"I would say that across the board, there was nonchalance," Liebman told The Huffington Post. "It looked like a common case, but we found that there was a very serious claim of innocence."

Police and prosecutors treated the killing of Wanda Lopez at the Sigmor Shamrock gas station on February 4, 1983, like a robbery gone bad. A recording of the chilling 911 call from Lopez, a 24-year-old single mom working the night shift, captured her screaming and begging her killer for mercy.

De Luna, then 20, was found hiding under a pickup truck a few blocks from the gory crime scene. A wad of rolled-up bills totaling $149 was in his pocket.

Eyewitness testimony formed the bedrock of the case against him. Now, that testimony is perhaps most contested aspect of his conviction.

Cops brought De Luna back to the Shamrock. A customer filling his tank before the murder told police that De Luna was the man he saw putting a knife in his pocket outside the store. Another customer who rushed to the store's entrance when he heard Lopez struggling identified De Luna as the man who emerged. A married couple saw a man running a few blocks away and later identified De Luna in police photos shown to them.

With De Luna's record of numerous arrests for burglary and public drunkenness, plus a conviction for attempted rape and auto theft, it seemed like police had found the perp. But Liebman said De Luna took the fall in a case of mistaken identity.

Among the key findings in the Columbia team's report:

"If a new trial was somehow able to be conducted today, a jury would acquit De Luna" said Richard Dieter, executive director of the Death Penalty Information Center, who read a draft of Liebman's report. "We don't have a perfect case where can agree that we have an innocent person who's been executed, but by weight of this investigation, I think we can say this is as close as a person is going to come."
