Police released video of a person who they want to talk to as they continue the search for missing 8-year-old Relisha Rudd.
Police only want to speak to the man, saying he may have information relevant to the case. And police won't say where the video was taken, saying that the location could hurt their investigation into Relisha's disappearance.
Relisha's mother told News4's Shomari Stone she does not recognize the man in the video.
The video appears to have been taken in a Metro station. In it, a man dressed in a dark hoodie with dark pants and a black bomber-like jacket, strolls off an escalator and walks to the left.
The only Metro station ever mentioned in this case was the Southern Avenue station, where Tatum was last seen March 20 after the slaying of his wife, sources said.
Anyone who can identify the person or knows where he is should call police at (202) 727-9099 or text the Department's tip line at 50411.
The last confirmed sighting of Relisha was March 1, when she was in the company of a 51-year-old janitor at the homeless shelter where she and her family lived.
That janitor, Kahlil Tatum, was found dead in a D.C. park Monday. Police believe he committed suicide.
