High-Risk Sex Offender Breaches Release In Vancouver

Vancouver police are trying to locate a high-risk sex offender with ties to Calgary and B.C.'s Sunshine Coast, who breached conditions of his release while under a federal supervision order.

James Patrick Benson, 32, walked away from the halfway house he was staying at in Vancouver late Thursday night.

Police said Benson has a criminal history dating back to the early 1990s, which includes convictions for sexual assault, attempted murder, extortion and various property and weapons offences committed in the greater Calgary area.

Benson was staying at the halfway house while under a federal Long Term Supervision Order.

Vancouver police said that Benson has been the subject of past public notifications. He breached his release conditions at the end of February 2011, and was found about a week later in Port Mellon on the Sunshine Coast at a friend's house.

Police describe Benson as white, five feet eight inches tall and 200 pounds, with short brown hair and brown eyes. He has prescription glasses and has scars on his left forearm and left calf.

He also has several notable tattoos: the word "morbid" in a tribal-style font on his left forearm; the date "01-17-07" on the inside of his left wrist; the words "lost soul" on his upper chest; a flame design on this left thigh; and a tribal art design on his upper right arm.

Police said anyone who sees Benson should not approach him, and should call 911.
