Convicted killer Jeffrey Landrigan was executed by injection Tuesday in Arizona after the U.S. Supreme Court lifted a restraining order that questioned the safety of a foreign-made chemical used in the execution.

Due to a resource shortage at its only American manufacturer, sodium thiopental, a sedative, was given by a British company. Landrigan’s lawyer’s petitioned the execution because federal inspectors hadn’t had time to approve the drug’s overseas manufacturers.

Landrigan was sentenced to death after the 1989 robbery and murder of Chester Dean Dyer in Phoenix. This happened while Landrigan had escaped from prison where he was doing time for second-degree murder.

Landrigan was pronounced dead at 10:26 p.m. Tuesday night at the Arizona State Prison Complex in Florence. This marks Arizona’s second execution in 10 years.

In his last words, Landrigan thanked his family and chanted  “Boomer Sooner” — a popular Oklahoma football call.
