PRINCE GEORGE, B.C. - The search for the remains of a missing 25-year-old Alberta woman is over.

But the question remains -- What, if anything, did the Mounties find at the two sites in northern B.C.?

Corporal Annie Linteau says it's too early to say whether investigators found any human remains or other items of interest at either site.

Police wrapped up work yesterday at a two-hectare property near Prince George and at an unauthorized community dump about a kilometre away.

They began searching the first property last week for the remains of Nicole Hoar, from Red Deer, Alberta.

She disappeared June 21, 2002, while hitchhiking along Highway 16 west of Prince George on her way to visit her sister in Smithers, B.C.

The RCMP say Hoar's case is part of a broader investigation into the fate of 18 women who have been killed or disappeared in the region during the past several decades.

Nearly all of the women have been aboriginal, although Hoar was not.

Linteau says the renewed focus on the case has prompted about 100 tips from the public.

Last week, police obtained a warrant to search a property once owned by convicted murderer Leland Vincent Switzer, who shot his brother to death two days after Hoar disappeared.

Switzer's former defence lawyer says an investigator interviewed Switzer about Hoar in 2004.
