The search for Dorothy Tucker in the St. Stephen area has entered its fifth day and now includes RCMP divers.

They are searching the waters off of the wharf in Bayside for any evidence that may assist in locating Tucker, said RCMP Staff Sgt. Jeff Johnston.

Ground and aerial searches in southwestern New Brunswick are also ongoing, said Johnston.

"We have a ground team searching and combing through the wooded areas," with the help of major crime investigators and the RCMP police dog, he said.

The RCMP helicopter will continue to be used in the search, Johnston said in a statement issued Sunday afternoon. An unmanned aerial vehicle equipped with cameras was also used earlier this week.

Tucker, 53, of Oak Haven, was reported missing on Nov. 10, but the last known contact with her was on Nov. 9 shortly before 10 p.m.

Investigators suspect foul play in her disappearance, based on undisclosed evidence found at her home, and continue to urge anyone with information to come forward, said Johnston.

"Police have spoken to many people, but again, we're asking for anyone who may have any information related to the disappearance to contact us or Crime Stoppers," he said.

The search for Tucker initially focused in and around her home on McGeachy Lane. A shed on the property was taped off, at least three vehicles were towed, including two cars and a white pickup truck, and officers carted away a series of cardboard boxes.

Extensive searches have also been conducted in the Waweig area, said Johnston.

But officers have now expanded their efforts throughout St. Stephen, which is about 10 kilometres west of Oak Haven, he said.

Tucker is a care worker and a foster mother, who lives with her adult son, according to area residents.

Neighbours say they're shocked by her disappearance.

Tucker is described as five-feet-five-inches tall, with a medium build, shoulder-length auburn hair, blue eyes and glasses.

She may have been wearing a navy blue sweater, dark coloured jeans with rips on the front and tan boots.
