It is a sordid homicide that dragged three teen girls and their John from the Backpage escort service to the front pages of this newspaper.

Now the teenagers have pleaded guilty to their roles in the stabbing death of Hayder Qasim-Rushdi, whom they planned to carjack after he struck a deal with them that had one girl riding naked in his passenger seat.

The girls, who cannot be identified under the Youth Criminal Justice Act, pleaded guilty Friday as court heard Hayder, 32, was stabbed in the neck, the back of his head and under his arm.

The first girl, 17 and from Hamilton, pleaded guilty to manslaughter. An 18-year-old (she was 17 at the time of the homicide) who is from the Toronto area and who wore a white wig during the homicide, pleaded guilty to robbery. A 17-year-old who is also from the Toronto area and wore an orange wig, pleaded guilty to robbery. They were all initially charged with second-degree murder.

An agreed statement of facts says that on April 27 this year the girls were staying in a room at a Super 8 Motel in Mississauga. Just after 8 p.m., the Hamilton girl and the orange wig girl went to a Husky Gas Bar and bought a blue-handled knife for $19.20.

A "third party" was supposed to pay for their motel room but didn't and, a few hours after buying the knife, the teens were evicted with the help of Peel Regional Police.

The girls had been working as escorts and the Hamilton teen advertised her availability on the Backpage escort service website.

Hayder, who lived with his mom in Mississauga and drove her white Jaguar, had been in touch with Backpage previously. Court heard he had offered to drive escorts around, provided they paid for gas and sat naked in the passenger seat.

The Hamilton girl already had Hayder's cell number. The girls devised a plan to get a ride to Hamilton with Hayder so the Hamilton girl could pick up clothes. Then they would steal his car.

Hayder picked the teens up at the Super 8 at 1:10 a.m. on April 28.

In keeping with the "arrangement," the Hamilton girl sat naked in the passenger seat. The other girls were clothed and in the back seat.

The Hamilton girl directed Hayder to a field at Ridge Road and First Road East on the Stoney Creek Mountain. Court heard she then held a knife to his neck and announced the carjacking.

Court heard everyone got out of the car (the Hamilton teen had put clothes back on) and the girls played "keep away" with the keys. Hayder intercepted them and got back into the driver's seat.

"Exactly what happened next and the precise order is unclear," says the agreed statement. The girls told police Hayder punched the orange wig girl in the mouth and put her in a headlock. The white wig girl passed the knife to the Hamilton girl who stabbed Hayder in the neck.

All the girls fled the scene, throwing Hayder's phone into the field. They called a taxi and got into the back seat.

Meanwhile, Hayder honked his horn trying to get help. A woman driving by did not stop because she was "nervous" at the site of him, covered in blood. She saw him drive toward a gas station and she later came forward to police as a witness.

Hayder drove to the Pioneer Gas Bar on Upper Centennial Parkway and got inside before coughing up blood and collapsing at 2:35 a.m. When a paramedic asked who had hurt him, he said "girls" and "three." When asked about the weapon, he said "knife."

The blue-handled knife was found in the driver's seat of the Jaguar.

The trio went to the home of the Hamilton girl's grandmother on Hamilton Mountain. The police later found the knife receipt there and an orange wig.

Court heard that Hamilton police seized surveillance videos from the Super 8, the Husky Gas Station, a house by the field, the Pioneer station and the taxi. Fingerprints from all three girls were found inside the Jaguar.
