A 59-year-old American, who had been sentenced to life imprisonment for the murder of two men in 2001, was executed today by lethal injection in Oklahoma, the correctional service of this US state announced.

Philip Hancock’s execution at the Macalister City Jail is the 24th this year and the last scheduled for 2023 in the US. All were carried out by lethal injection in a total of five US states: Texas, Florida, Alabama, Missouri and Oklahoma.

Hancock was sentenced to death in 2004 for the April 2001 murders of biker gang members Robert Jett and James Lynch.

He claimed he was in self-defense and was lured to the home of Robert Jett, who was under the influence of methamphetamine, and tried with James Lynch to lock him in a cage to torture him. According to Hancock’s version, which did not convince jurors, he managed to grab Robert Jett’s pistol and shoot the two men before fleeing.

The state board that reviews requests for pardons and paroles had recommended on Nov. 8 that Philip Hancock’s sentence be commuted to life in prison, but Republican Gov. Kevin Stitt rejected it.

The death penalty has been abolished in 23 US states, while three others – California, Oregon and Pennsylvania – have imposed moratoriums on executions.
