A middle-aged woman has keyed more than 400 vehicles “one-by-one” at two Canadian dealerships over the course of four months, resulting in over $500,000 in damages.

Video surveillance released by the Royal Canadian Mounted Police (RCMP) shows the woman wearing glasses, a gloves, a beanie and a surgical mask while meandering through a dealership and scratching the exterior of each car with a tool.

The RCMP released one minute and 23 seconds of surveillance footage on YouTube. It’s starts with a clip dated April 7, 2023, at around 9:20 p.m. and shows the unidentified woman keying at least four Ram pickup trucks.

At one point, she even appears to look up at the security camera before continuing on her damaging rampage.

In video then cuts to another clip from around 8:24 p.m. the same night, where the same woman appears to be in a different coat that’s long, black and hooded, resembling a cloak.

She was recorded in what appears to be the front of the dealership, messing with the front doors before keying the blue pickup truck parked out front.

The video then cuts to surveillance from Jan. 15, 2023, showing the woman holding an umbrella as she walks down a line of rain-soaked cars, slashing a scratch in the hoods with a tool.

The police report said the “mass car keying incidents” took place at two dealerships in British Columbia — a Journey Chrysler Jeep Dodge and Ram dealership and a Journey Approved Dealership in Port Coquitlam.

The two dealerships are located just under one mile from each other.

Police received three separate reports of the keying, RCMP said. “It is clear in the videos that the suspect was deliberately scratching the vehicles one-by-one,” corporal Alex Hodgins of the Coquitlam RCMP added in the report.

She added that the investigation is ongoing, and the police have yet to identify the woman in the surveillance video.

The RCMP described the suspect as a Caucasian female aged between 40 and 50, with shoulder-length blonde hair and a heavy build.

The police said the woman is believed to be driving a 2008-2013 Ford Escape.
