An Edmonton man will spend at least 12 years in prison for killing his common-law wife by slashing her with a box cutter.

Irineo Odoy, 62, pleaded guilty on Monday to second-degree murder in the February 2011 death of Marietta Echavez.

A month before Echavez was killed, Odoy moved out of the couple’s home.after he became convinced she was having an affair.

The couple had a confrontation the day Echavez was killed in the basement suite of a home at 40th Avenue and Millbourne Road West. 

The court heard that Echavez slapped Odoy after he called her a name during a confrontation. He then grabbed a box cutter and slashed her 35 times, leaving her dead on the floor.

Odoy then called a friend and confessed.

“I slashed her neck, then I blacked out,” Odoy told him. “I killed her.”

The judge agreed with a joint submission by the Crown and defence lawyers that Odoy should serve 12 years of his life sentence before he can apply for parole.
