Police in Maine are searching for a mother of three who was not been seen in three weeks, and her family has increased a reward for her safe return.

Kerry Rear, 40, of Kittery, Maine, was last seen on the evening of January 22 at a convenience store in Sanford, where, according to the Journal Tribune. police said Rear appeared “disoriented and wet and in her stockinged feet.”

Sanford Police Det. Sgt. Matthew Jones said the clerk told police, “[Rear] was extremely disoriented and believed she was in a bank.”

Sgt. Jones said Rear had two conversations with L’il Mat store employees and at the adjacent McDonald’s before leaving on foot. Then, within minutes of leaving, she went back to the store and asked clerks the same questions as she had earlier — inquiring about making a bank deposit.

She was reported missing on Jan. 28, by her father, who lives in Florida, after she had not been in contact or reachable for several days.

Police told local news station WGME earlier this month that a tracking dog followed her trail to Dover, New Hampshire, where they believe she got into a car and made several stops in New Hampshire.

At the press conference Tuesday, Rear’s father said she was a “wonderful girl.” He acknowledged that she is a troubled woman, but that she always calls her parents. Her family had previously offered a $5,000 reward for information leading to her whereabouts, and this week added an additional $10,000 reward “to the person who provides direct information which leads to the safe return of their daughter, alive.”

Rear was last seen wearing brown sweat pants and a black puffy jacket with a hood with pink lining.  She is five feet six inches tall and weighs about 135 pounds.

Anyone with information is asked to call Sanford Police Det. Eric Small at 324-9170, ext. 22.
