FARMINGTON — A 13-year-old Canadian girl involved in a police chase Monday night was in stable condition at Maine Medical Center in Portland on Wednesday, Stephen McCausland, spokesman for the Maine Department of Public Safety, said.

The girl from Pembroke, Ontario, was a passenger in a stolen car that failed to stop at the U.S. border. She has not been charged, McCausland said.

The driver, Zachary Wittke, 16, of Eganville, Ontario, denied charges of eluding an officer, passing a roadblock and aggravated criminal mischief in Juvenile Court in Farmington on Tuesday. He is on probation in Canada and has warrants for his arrest there, Assistant District Attorney Joshua Robbins told the court.

He is being held at Mountain View Youth Development Center in Charleston.

The two teens led police on a “wild chase” down Route 27 in Kingfield with speeds reaching 100 miles per hour, McCausland said.

Wittke is accused of ramming a Border Patrol vehicle, prompting a Border Patrol agent to shoot at the fleeing car, police said. The stolen car from Canada was ditched in Kingfield. Wittke is accused of stealing a truck in that town and leading police on another chase.

The truck ran over two spike mats and kept going on flat tires before police used a cruiser to slow it down. The truck hit a guardrail and the two teens jumped over it, went down a rocky embankment and landed in the Carrabassett River in Kingfield, McCausland said.

Both were injured. Wittke was treated and released from a hospital, and the girl was eventually taken to Maine Medical Center.

The crime spree started over the weekend in a stolen vehicle from Ontario, chased by Canadian police and later found abandoned in Sherbrook, Quebec, McCausland said.
