As the police presence dwindles at the murder scene behind CEGEP de l'Outaouais near Gatineau Park, local residents are once again worried about their safety in the area.

Police said they have no suspects in the murder of 18-year-old Valerie Leblanc, found behind the school on Tuesday.

They're encouraging residents to travel in groups and let people know where they're planning to go.

"When we are in a group I feel safe, because if someone popped out we are all together to help each other," said one walker in the park.

"I told myself there is a very small minority of creeps in the world," said Louie Auriat. "They are distributed all over the world."

The RCMP is responsible for policing Gatineau Park and said they are increasing patrols this weekend.

Still, the many paths and shaded areas of the 363 square-kilometre park can make it difficult for police to find suspects.

There have been multiple reports of naked men in the park over the last few years, according to the Ottawa Citizen.

In June, two women responding to an ad for a photo shoot were told there was a naked man masturbating in the bushes who later started to follow one of the women.

Police also assigned undercover officers to walk the park's trails a few years ago after multiple reports of a male flasher.
