EDMONTON — One of two men convicted in the deaths of four Alberta Mounties has been arrested.

Alberta RCMP ‘K’ Division confirms Dennis Cheeseman was arrested for possession of a controlled substance.

Sgt. Steve Vince with Strathmore RCMP says he was arrested in Whitecourt on Friday after a member of the public reported a suspicious vehicle to the local RCMP detachment.

“Whitecourt RCMP did locate the vehicle and found Mr. Cheeseman to be in possession of a controlled substance. Mr. Cheeseman was arrested for that and is still currently in custody,” Vince shortly before 8 p.m. Friday.

Cheeseman was granted statutory release in November 2013 after serving two-thirds of his seven-year, two-month, 15-day sentence for manslaughter.

When Cheeseman was released, it was on conditions that he abstain from drugs and alcohol and not associate with criminals until his entire sentence expires on April 13, 2016.

“The possession of the substance is a breach of Mr. Cheeseman’s parole and the RCMP have advised the National Parole Board of this breach,” added Vince.

Cheeseman and his brother-in-law, Shawn Hennessey, pleaded guilty to manslaughter for giving James Roszko a rifle and a ride the night before Roszko ambushed the RCMP officers on March 3, 2005, near the town of Mayerthorpe.

The Mounties — Constables Peter Schiemann, Anthony Gordon, Brock Myrol and Leo Johnston — had been guarding a hut on Roszko’s farm as part of a marijuana grow-op and automobile chop-shop investigation.

Earlier this week, Hennessey was granted more unescorted, temporary absences from prison after the Parole Board of Canada said he was doing well behind bars. He will be allowed to visit his family for up to 78 hours, once every month, for six months.
