GATINEAU, Que. - Police in western Quebec looking into the slaying of an 18-year-old girl have launched a separate probe to determine who tampered with her body.

Passersby found Valerie Leblanc beaten and burned on Tuesday in Gatineau Park, near a college just across the river from Ottawa.

Police have not yet made any arrests.

Authorities have also launched a separate probe that may result in charges of obstructing justice and causing an indignity to a body.

"We have four suspects in this investigation," Gatineau police spokesman Jean-Paul Lemay said Thursday.

"They aren't related to the murder investigation and aren't responsible for the death of Valerie Leblanc."

All four were released.

Lemay said Leblanc was a student at the college in Gatineau, but little else about her indicates why she was killed.

"Valerie Leblanc is someone without any history with the Gatineau police," Lemay said.

"We know that she'd broken up with boyfriend, also a student, and he too isn't known to police."

Police met with the minor and say he's not implicated in the case.

An autopsy will be performed in Montreal to determine the cause of death.
