York Regional Police say they have identified the man in a newly-released surveillance video from the night 25-year-old Taneesha Brown was last seen.

The footage, which is taken from cameras at the Bur Oak Secondary School, shows a person believed to be Brown walking at about 10:48 p.m. on Tuesday, Jan. 12, 2016.

In the video, a man enters the frame, walking towards Brown. Brown pauses and turns to face him, and then the two can be seen speaking with each other. After a short conversation, they turn and walk away in opposite directions.

Brown is seen heading south, towards 16th avenue.

As a result of the video, police say they are now conducting operations on the ponds west of the secondary school. A press release says officers plan to use a remotely operated vehicle to check areas of open water in the partially frozen pond.

Police say the man is not a suspect, but is considered a "witness who had a brief conversation with her before she walked away."

Investigators hope to talk to the man about his conversation with Brown that could help them locate the missing woman.

Brown was last seen by family members at about 10:30 p.m. on January 12, in the area of McCowan Road and Castlemore Avenue. Her family said she told them she was "going outside for some fresh air," but never returned home.

Brown is described as black, 5-foot-5 and weighing approximately 122 pounds. She has black, shoulder length hair with pink highlights.

Officers say she was last seen wearing a traditional Muslim outfit with a white, knee-length dashiki, white pants and a white hijab. She was carrying a black purse.

Anyone with more information is asked to contact police at 1-866-876-5423, ext. 7541, or Crime Stoppers anonymously at 1-800-222-8477 (TIPS).
