WINNIPEG -- Police in Winnipeg say they're shutting down a national tipline that was set up to gather information on a drifter accused of killing three women.
The phone line was set up last summer to assist investigators in the case of Shawn Cameron Lamb.
Lamb is accused of second-degree murder in the deaths of three aboriginal women.
The line was set up in part to determine whether he might be connected to any unsolved cases across Canada.
In October, police said dozens of people had called the tipline with details that in some instances prompted investigators to interview previous callers.
Anyone who may still have information is being asked to call Crime Stoppers or the Winnipeg police homicide unit, which continues to investigate.
Lamb is accused of killing Tanya Nepinak, Carolyn Sinclair and Lorna Blacksmith.
Blacksmith, 18, was found dead in January 2012. Sinclair, 25, died last March. Both bodies were found wrapped in plastic near garbage bins.
Nepinak's body has never been found. It's believed the 31-year-old was dumped in a garbage bin that was emptied in the Brady landfill just south of the city. Police searched a section of the landfill, but found no sign of her.
Lamb's arrest in June prompted renewed calls from aboriginal leaders for a national inquiry on missing and murdered aboriginal women. The federal government has rejected the idea.
