Ottawa police are still pursuing Claude Legare after his ex-girlfriend, Brenda Van Leyen, was attacked outside a Shoppers Drug Mart on Strandherd Road Friday night.

Leyen, 47, was stabbed several times at the Barrhaven location - as was a 21-year-old Shoppers employee who tried to stop the attack. Family members say she had recently left Legare. She is listed in serious condition at the hospital and said to be fighting for her life.

Charges for Legare include attempted murder and aggravated assault, among other things.

As police responded that night, one cruiser crashed into a pedestrian, sending a 43-year-old to hospital with head and leg injuries.

The force's special investigations unit is looking into the incident.

Police say Legare, 35, has a scruffy appearance, and was wearing a dark hooded sweatshirt, a dark baseball cap, light grey track pants and dark winter shoes when last seen. He is described as white, five feet seven inches and 205 pounds.

Anyone with information should contact Ottawa police at 613-236-1222 ext. 5493 or Crime Stoppers at 613-233-8477 (TIPS).
