The search for Amber Kirwan's killer led police to a home in Heathbell, Nova Scotia late Tuesday afternoon, and investigators expect to be there for a while.

Pictou County RCMP executed a search warrant at a home on the Hardwood Hill Road just after 4:00 PM.

More than a dozen officers, including the Major Crime Unit, are working at the scene, and investigators expect to be there well into Wednesday.

Police were also stopping vehicles along the road, checking for identification before allowing cars to drive through.

The house is about three kilometres from where Kirwan's body was discovered last weekend.

The search of the home was the latest in a flurry of developments in the case in the last couple of days.

On Monday, police also seized a car.

"There has been a 2002 grey Chev Impala that has been seized as the result of a warrant, and that vehicle was seized at approximately 4:15 p.m.," said Cst. Bill Rudolph from the New Glasgow RCMP told CTV News.

"The vehicle is now being examined for evidentiary purposes."

Police aren't saying who owns the car, or where it was seized.

Investigators took down the barricades blocking public access to Heathbell Road earlier today.

Kirwan's remains were found on a logging trail, just off the road on Saturday afternoon.

Local residents say the whole ordeal has been a nightmare.

"You know, it's been overwhelming living here," says resident Jackie Sutherland. "There's been some sleepless nights since all this has been happening."

An intense search for the missing teen began last month after she disappeared from a New Glasgow pool hall.

Her friends say she left Dooly's around 1:30 a.m. on October 9 with the intention of meeting her boyfriend at Big Al's, a nearby convenience store.

Kirwan is seen leaving Dooly's and walking up the street towards Big Al's, but Mason Campbell says she never showed up, and Kirwan doesn't appear on surveillance tapes from the parking lot at Big Al's.

Police, RCMP divers and ground search and rescue teams conducted extensive searches throughout parts of Pictou County, including the Heathbell area, last month.

Local residents also took part in the search effort and volunteered their time passing out posters and putting them in store fronts, businesses, and on telephone poles.

Numerous vigils and fundraisers have also been held for Kirwan and her family, as community members try to cope with the devastating loss.

"It's not the outcome we had hoped for," said resident Michele Ferguson on Monday. "It's a very sad day. It's been hard on the whole community."

As for Kirwan's death, an autopsy has been performed, but police say they won't be releasing the cause of death.

"We will not be making any further comment in relation to the autopsy," said Rudolph.
