A Lewiston man was sentenced Friday in federal court to more than 15 years in prison for using a firearm during a Minot home invasion.

Kourtney Williams, 27, appeared in U.S. District Court where Judge Jon D. Levy sentenced him to five years of supervised release after his prison term.

Williams was convicted by jury more than a year ago in federal court in Portland.

According to a news release from acting U.S. Attorney Richard W. Murphy, Williams was armed with a pistol on Aug. 2, 2014, when he and associates, one of whom had a crowbar, broke into a home on the Garfield Road in Minot. He and his co-conspirators intended to steal drugs and money from the residents. Williams used the pistol to repeatedly threaten and assault the occupants of the home, the release said.

Co-defendant Victor Lara Jr., 33, was also sentenced a week ago to 184 months behind bars and five years of supervised release. He was convicted of interstate robbery conspiracy and using a firearm during a violent crime.

Like Williams, Lara was convicted at trial.

Authorities said Lara was armed with a crowbar.

The victims suffered minor injuries.

The investigation was conducted by Maine State Police, the Lewiston and Auburn Police Departments, the U.S. Drug Enforcement Administration, and Bureau of Alcohol, Tobacco, Firearms and Explosives.
