A convicted killer was executed yesterday 16 years after he shot four people to death in Oklahoma.
Gilbert Ray Postelle opened fire on the victims, James Alderson, 57, Terry Smith, 56, Donnie Swindle, 49, and Amy Wright, 26, at a trailer park home in 2015.
He later claimed he didn't remember the killings, which were carried out using an AK-47 rifle, because of his heavy use of crystal meth in the preceding days.
