The surveillance footage shows Brittany Tee, of Brookfield, in some kind of convenient store on Friday, Jan. 6, the Worcester County District Attorney's Office reports.
Tee was last seen leaving a house on Main Street in Brookfield around 8:30 p.m. on Tuesday, Jan. 10, and her family reported her missing to Brookfield Police the following Friday.
Worcester County District Attorney Joseph Early Jr. had said the family did not immediately report her disappearance because there was some confusion about her exact location.
A ground search for the 35-year-old will continue in Brookfield on Saturday, Early said in a recent update. Massachusetts State Police's Marine and Dive units will conduct the search along with Environmental Police and Worcester Police.
"Whenever you get additional agencies it's a force multiplied," Early said. "In the meantime, investigators are continuing to review all the video that's been submitted...and all the tips that have been coming in."
Tee is described as 5-foot-6, weighing 120 pounds, with brown hair and blue eyes. She was last seen wearing a black winter coat, a hoodie, jeans and work boots, authorities report.
Since her original disappearance, investigators have expanded their search to three miles outside the immediate area from which Tee was reported missing, MassLive reports.
A custom Tip Line has also been established for people to call with any information regarding Tee's disappearance. People can reach the Tip line at 508-453-7589.
Anyone else with information about her whereabouts is asked to contact Massachusetts State Police Troop C Headquarters at 508-829-8326 or the Brookfield Police at 508-867-5570.
Residents are also still encouraged to send in any digital assets they may have to help search parties narrow their investigation.
