The state of Arizona executed convicted killer Jeffrey Landrigan late Tuesday after the U.S. Supreme Court cleared the way for the lethal injection.
The execution was carried out at 10:26 p.m. local time, according to a correction official.
Landrigan's attorneys filed a civil rights complaint last Thursday alleging the planned execution violated his constitutional rights to be free from cruel and unusual punishment and to due process.
On Monday, a U.S. District Court judge issued the temporary stay after concluding that the state did not provide Landrigan's side enough information to make its case sufficiently about the safety and legality of substances that would have been used to kill him.
In 1989, Landrigan escaped from an Oklahoma prison, where he was serving time for second-degree murder. He was convicted of strangling Chester Dean Dyer in Arizona a year later during an armed burglary, and a trial judge sentenced him to death.
