NEW GLASGOW, N.S. - A candlelight vigil was held Wednesday night for a young Nova Scotia woman who's been missing for four days.

About 100 people gathered at Glasgow Square in downtown New Glasgow as efforts continued to find 19-year-old Amber Kirwan.

The New Glasgow woman was last seen leaving a local pool hall early Sunday morning.

Searches have been conducted in New Glasgow, Trenton and the Hillside area, just outside Trenton.

Sniffer dogs were used to search abandoned buildings in New Glasgow and rescue boats have been combing the East River.

Police say they're conducting interviews with potential witnesses and are still receiving tips from the public.
