Tee's sister, Bethany Tee, said it "is very unlike" the 35-year-old "to not be in contact with her family" in a Saturday Facebook post.

"We are desperate to find her, we love her very much," she wrote. 

In another Facebook post, Bethany Tee clarified that her sister "did not leave in her car," which "was not running well and it was left where she lives."

"So she left on foot or was picked up by someone. The most helpful thing at this time is to contact people that know her that may have any information, which we have been doing, to give any leads. No information is too small," she wrote.

Authorities and Tee's family are asking anyone with information about her whereabouts or last points of contact to call the State Police Troop C Headquarters at 508-829-8326 or the Brookfield Police at 508-867-5570. Anyone with security cameras in the area of Main Street in Brookfield is also asked to contact police.
