Coroner investigates death of woman who may have been distracted by cellphone

MONTREAL - A coroner is investigating the death of a young woman who died because she may have been distracted by her cellphone while in the Montreal subway.

Coroner Catherine Rudel-Tessier will try to determine the circumstances surrounding the death of the 20-year-old woman, which occurred last Friday.

Audrey-Anne Dumont died after apparently becoming trapped between two Montreal subway cars; she was dragged along for two stops before other commuters noticed blood on the tracks.

They alerted authorities, who then shut down part of the metro line during the morning rush hour.

Video footage from the subway reportedly shows the young woman, wearing earphones and staring into her smartphone, as she stepped into a gap between the subway cars.

The possibility that she may have committed suicide will also be considered. Initially, authorities had suggested the death might have been a voluntary act.

No one witnessed the incident.

The Montreal transit commission has sent authorities copies of the video which was captured by surveillance cameras.
