RCMP are still on the scene at a mobile home in Heathbell tonight, in connection to the Amber Kirwan murder investigation.

"It is a property which includes the residence, and the residence is being searched in the circumstance," says RCMP spokesman Const. Bill Rudolph.

More than a dozen officers, including the major crime unit, executed a search warrant at the home on Hardwood Hill Road, which intersects with Heathbell Road, around 4 p.m. yesterday afternoon.

A forensic unit was also on the scene today, scouring the area with metal detectors.

The home is roughly three kilometers from where police discovered Kirwan's body on Saturday.

Police haven't confirmed who owns the home, but neighbours say Alice Meier, the stepsister of Christopher Alexander Falconer, lives there.

Falconer was one of two men convicted of second-degree murder in the killing of cab driver Bob LeBlanc on Heathbell Road in 1998.

Police confirmed to CTV News that Falconer was picked up on Brother Street in New Glasgow, not far from where a car was seized Monday afternoon on Vale Road.

Witnesses say Falconer was walking down the street when he was approached by police and patted down Wednesday afternoon. They say he was then taken away in a police vehicle.

"It was pretty quiet, he went willingly," says area resident Stephanie Fanning. "They took him and they put him in his cuffs and they put him in the car."

At this time we do not know why Falconer was picked up, but RCMP say there have been no arrests made in connection with the Amber Kirwan murder investigation.

"At this time police do not have anyone in custody," Rudolph tells CTV News.

Police also say they aren't sure how long they will be on the scene in Heathbell, but they expect their investigation at the home will continue tomorrow.

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 her boyfriend 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.

They returned to Heathbell on the weekend to execute a search warrant on a farm property in the area when they discovered her remains on a logging trail, just off Heathbell Road on Saturday afternoon.
