Alberta RCMP link deaths of four young women in 1970s to serial killer 

Alberta RCMP have linked the deaths of four young women, five decades ago, to a now deceased serial sexual offender and killer.

Investigators with the Alberta RCMP Historical Unit will hold a news conference Friday where officers are expected to detail their investigation and provide more information on the victims. 

RCMP believe the same killer may have been responsible for other unsolved homicides. 

RCMP said the historical homicides, all dating to the 1970s, have been linked to the same killer. 

In a statement, police said they hope that releasing details of the investigation to the public will help them potentially solve other cold cases.

Following a technical briefing where investigators will provide more details on the case, RCMP will hold a news conference Friday at Alberta RCMP headquarters in Edmonton. The news conference is expected to begin at 11:30 a.m. MT.

CBC News will be reporting details on the investigation as they become available.
