BOISE, Idaho -

A Pennsylvania man convicted of a double killing that has been described as a murder for hire has been sentenced to life in prison.

The Idaho Statesman reports  that John C. Douglas of Reading, Pennsylvania, on Monday was sentenced for two counts of first-degree murder and one count of attempted murder in connection to the May 2014 killings of Travontae Calloway and Elliott Bailey. He was convicted in January.

Two other men, Samari Winn and Anthony Robbins, were sentenced in June to 40 years to life for aiding and abetting first-degree murder and attempted first-degree murder.

Police say Winn and Robbins hired Douglas to kill the victims after Calloway and Bailey reportedly stole 30 pounds of Robin's marijuana.
