Ont. home search continues in case of missing N.S. woman

Police in Grimsby, Ont. continued their search Tuesday of the house where a Halifax woman was living when she disappeared nearly two years ago.

Shana Carter's mother Elizabeth said she was surprised when police called to tell her they were conducting an extensive search of her daughter's home. Carter, originally from Halifax, hasn't been seen since she left the house in Grimsby back in December 2010.

"A bit of a shock, very confusing. You know, we're not sure what exactly is going on," said Carter's mother. "We're just hoping it will bring some kind of answer."

At the time, 25-year-old Carter was living in Grimsby with her boyfriend and infant son.

Carter's mother, who lives in Dartmouth, said although her daughter led a somewhat troubled life, she had turned things around and would never disappear without her son, or without contacting family and friends.

"I figure if she was out there she would have called somebody by now, somebody would have heard from her," she said. "We've had no contact, no word, no activity on her phone or bank account or anything since that day."

She said after all this time, the family just wants to know what happened.

"It is very difficult, it doesn't get any easier as the days go by… I'm just grateful the detectives are still actively searching after all this time."

Det. Don Massotti of the Niagara Regional Police Service wouldn't say what prompted them to execute a search warrant at Carter's home, but said they believe she was the victim of foul play.

Massotti said police conducted a ground search and a search of ponds around Grimsby recently but wouldn't comment on whether anything was found related to Carter's disappearance.

Police are asking anyone with information in this case to contact the Niagara Regional Police Major Crime Unit at 905-688-4111.
