It is being called one of the most brazen of crime sprees, a case so unusual that justice officials have been unable to find any similar scenarios across Canada.

Two chronic Winnipeg car thieves -- a 16-year-old girl and her 18-year-old boyfriend -- spent an entire month wreaking havoc across the Prairies by stealing vehicles, gas, property and leaving a trail of costly damage in their wake.

In the process, they documented nearly every one of their crimes by taking pictures and videos that show them taunting police, drinking and driving, boasting to their friends and celebrating their accomplishments by dancing and making out on the top of stolen vehicles.

"In all my years ... there has never been anything like this," veteran Crown attorney Elizabeth Laite told a Winnipeg courtroom Tuesday.

"This resembles a fantasy story. You would think Hollywood would come up with something like this," added her colleague, Stephanie Hermiston. "It is an exceptional case, extraordinary circumstances."

The female accused -- who can't be named under the Youth Criminal Justice Act -- has pleaded guilty to 21 separate crimes during the August to September 2009 rampage.

These include thefts, possession of stolen property, mischief and breaches of court orders. Her adult co-accused is expected to deal with his charges next month. He faces a lengthy prison term.

The Crown plans to show some of the photos and videos in court when the sentencing resumes. They are seeking the maximum youth sentence of two years behind bars for the girl, who has a long history of property offences and was on probation at the time. She is a Level 4 auto thief, the highest risk category assigned by police, and has been turned in to police by frustrated parents who are unable to control her.

Manitoba Provincial Court Judge Rocky Pollack adjourned the hearing until Aug. 19 for completion of a pre-sentence report probing the girl's personal background, prospects for rehabilitation and suggestions for controlling her in the community.

The two accused -- dubbed Bonnie and Clyde by some justice officials -- were sentenced last June for a variety of car thefts and property crimes. She got 18 months probation, while the young man got two years of custody less time already served. Both were ordered by the courts to stay away from each other.

In August, the man was released on a day pass from jail to go shopping with his mother. While browsing through the aisles, he suddenly took off, stole his mother's car and picked up his girlfriend.

The pair then embarked on 30 days of chaos across rural Manitoba, Saskatchewan and Alberta, court was told.

"They were flouting court orders, and thumbing their noses at society," said Hermiston.

They burned a Hummer they stole outside Winnipeg, nearly mowed down a vehicle owner who tried to interrupt a theft in eastern Saskatchewan, and scrawled lyrics to a crude rap song in the interior of another car they left behind to be found by police.

The pair would typically steal a vehicle, drive it for a few hours or days, cause extensive damage and then "trade" it for another one.

In one case, a rural Manitoba resident woke up to go to work and found his car missing, with a damaged one sitting exactly in its place.
