SANFORD — Police here are looking for Christopher William Gonyer, 40, whose probation for stabbing the mother of his children and a Sanford Police officer with a screwdriver back in 2006 has been revoked. Gonyer allegedly fled from the office of his probation officer in Biddeford Nov. 4 and hasn’t been seen since, say Sanford Police.

“Gonyer’s probation has been revoked and he is currently wanted for arrest and is considered dangerous,” said Det. Sgt. Matthew Jones in a news release. “Gonyer has ties to Sanford and Old Orchard Beach as well as Haverhill, Massachusetts, and Sandwich, New Hampshire.”

Gonyer in 2006 pled guilty to punching his former girlfriend in the stomach and then stabbing her, her friend and a Sanford police officer with a screwdriver. He was sentenced to spend four years and nine months of an eight-year sentence in prison.

Anyone with information as to Gonyer’s whereabouts is asked to call Det. Eric Small at 324-9170, ext. 227. After regular business hours, call Sanford Police Department at 324-3644.

Sanford Police used non-lethal bean-bag rounds to subdue Gonyer on March 30, 2006 after he ran form the scene , with police in pursuit, through downtown neighborhoods.

During his sentencing in August 2006, Assistant District Attorney Justina McGettigan told the judge that Gonyer threatened to use the screwdriver to harm his former girlfriend. While a neighbor attempted to intervene before police arrived on the scene, Gonyer  carried out his threat.

“A neighbor approached him with a baseball bat to get him to release her but Gonyer said, ‘Go ahead, I’ll stab her,’” McGettigan told the court.

The assistant district attorney said Gonyer had his former girlfriend down on a porch and was dragging her when a friend also tried to intervene. McGettigan said Gonyer cut his former girlfriend with the screwdriver across the throat and continued to drag her along the porch. As the fracas continued, her friend was also stabbed with the screwdriver.

When Sanford Police Officer Mark Dyer arrived, he jumped over the porch to try and prevent any further assault and Gonyer drove a screwdriver into Dyer’s chest. The police officer was wearing a protective vest, and the screwdriver was deflected. Then Gonyer stabbed Dyer in the upper arm.
