The RCMP say a crew member who died aboard a supply ship that was en route to Montreal from Nunavut was a homicide victim.

Police say 30-year-old François Hébert of Quebec City was found dead in his cabin aboard the Umiavut on Sunday after he didn't report for work.

When the cargo ship anchored offshore at Blanc Sablon, Que., the Sûreté du Québec, Quebec's provincial police force, secured the vessel for the RCMP and Hébert's body was flown to St. John's for an autopsy.

Investigators say it's been determined the homicide occurred while the vessel was travelling in waters off the coast of Labrador.

The Mounties did not release Hébert's cause of death.

No arrests have been made and the vessel has resumed its trip to Montreal.
