CITY police are investigating the death of a 20-year-old woman who was struck by a car while crossing Fermor Avenue at Autumnwood Drive on her bicycle on Friday night.

The collision occurred around 9:50 p.m. Witnesses said the car was heading west on Fermor and proceeding through the intersection on a green light when the collision happened.

The victim was not wearing a helmet, witnesses said.

Her mangled bike lay near the boulevard, not far from a silver Oldsmobile Alero with a portion of its front windshield smashed.

Alain Touchette, 18, was at the intersection, facing south on Autumnwood waiting for the light to change, when a terrible scene unfolded before his eyes.

"I saw a girl flying high through the air, followed by her bike," he said.

An off-duty paramedic also waiting at the intersection raced from his vehicle to help the victim, as did two other people who later told witnesses they were lifeguards, Touchette said.

Emergency crews quickly arrived at the scene and took over the lifesaving effort.

"The worst thing was watching the paramedic over top of her, giving her CPR," said Marc Bellavance, 17, a passenger in Touchette's car.

"I didn't hear a word from her... it was gut-wrenching."

The woman died after being transfered to the St. Boniface Hospital.

Police traffic collision analysts were expected to be at the intersection for several hours, and westbound traffic on Fermor was re-routed through Windsor Park.

The stretch of Fermor is marked as a 70-km/h zone.
