A search for an elderly Brockville, Ont., woman missing since last weekend was called off Friday evening after ground and canine units spent the day combing a wildlife area north of the eastern Ontario town.

The search for Valerie Xavier, 80, was called off at about 5:30 p.m. ET. Police said at the time they would hold a meeting to decide whether the search would resume on Saturday.

Ontario Provincial Police Sgt. Kristine Rae confirmed Friday morning a ground search had resumed, but could not say whether dive teams or air units had been deployed.

Provincial and local police had searched into the night on Thursday in the Mac Johnson Wildlife area for Xavier, who was last seen Sunday at a family gathering. However, heavy rain made it difficult for dogs to pick up the scent, and a search helicopter had to be grounded until conditions improved.

On Monday, police arrested a 16-year-old Brockville boy who was caught driving her car.

Police have released little information, saying only that the missing woman and the suspect know each other. Neighbours said the woman had recently opened up her apartment to a teenager who needed a place to stay.

"[The boy] has been charged with theft over $5,000, possession of property obtained by crime as well as theft of credit card," said Rae.

"He was taken to court, appeared for bail hearing and is presently released on conditions."

The boy cannot be identified under the Youth Criminal Justice Act.

Police are asking for the public's help in locating Xavier. Anyone with information is asked to contact the Brockville Police Service at 613-342-0127.
