The young woman was found by a witness around 10 p.m. Tuesday on a dark, quiet stretch of the bike path that runs through Paul Pratt Park in Old Longueuil.
She had been savagely beaten. She died in hospital from her injuries a short while later.
Now Longueuil police are patrolling the area when the sun goes down, and confirm lighting has been improved in the area.
Trees that may have obscured bike path lighting have had their branches cut back, or have been cut down completely.
Police are still looking for suspects and ask anyone with information to go to a police station or call 911.
