A 15-year-old girl was found semiconscious early Sunday morning in a park in Brossard, on the South Shore.

Longueuil police said it is unclear if the girl was attacked or if there was some sort of accident or illness at play. The prevailing theory, however, is that she was the victim of some sort of crime, though police could not provide more details.

She was hospitalized. Her health status is currently unclear.

A passerby spotted the girl lying in Sorbonne Park, near a residential area and a school.

Investigators were dispatched to the scene.
