A family is mourning the loss of their teenage daughter after she was struck and killed by a car driven by her older sister.

The accident occurred on Attwell Drive, close to Toronto’s Pearson airport, on Saturday evening.

Police said the teen, 17-year-old Fartun Abdulle, was walking along the industrial road shortly before 7 p.m. when a car driven by her 18-year-old sister mounted a curb and struck the girl.

Police said Abdulle was dragged for a short distance until the car came to a stop. Investigators said she was trapped underneath the car for 15 minutes.

Individuals attending a nearby church saw the accident unfold.

“She was screaming ‘my sister, my sister, it was an accident. I hit her, I didn’t mean to,’” witness Melinda Jefferey told CTV Toronto. “She kept asking if she’s still alive.”

Lagos Csiki was walking along Attwell Drive when the accident occurred.

“The lady goes under the car and I touched her hand and prayed,” he said.

Abdulle was rushed to hospital where she was later pronounced dead.

Police said they do not expect any charges to be laid following the accident.

Officers also said alcohol and speed are not considered factors in the investigation.

Const. Clint Stibbe said police have downloaded the data from the “crash module” inside the car, which will give them a better idea of what happened mechanically moments before the crash.

Officers are continuing to investigate the case and would like to speak to anyone who may have witnessed the incident.

Anyone with any information about this case is asked to Toronto Police Traffic Services at 416-808-1900 or Crime Stoppers at 1-800-222-TIPS.
