Police have suspended their search for new evidence in the disappearance of Julie Surprenant.
The 16-year-old girl was last seen near her home in Terrebonne in 1999.
Provincial police divers spent two days searching a section of the Mille-Îles river.
They reportedly found a shoe and a medallion from the shallow search area, though it's not clear whether either article can be linked to the girl's disappearance.
The search was launched after police received new information about the case in January.
A nurse claimed that in 2006, a dying man confessed to her that he killed Surprenant and dumped her body in the river.
