The Metropolitan Police Department has come up dry once again in its search for 8-year-old Relisha Rudd, who was last seen March 1.

On Friday, MPD released a video asking for the public’s help in identifying a man in the footage in connection with the missing girl’s case. Officials announced today that they interviewed the man, he cooperated with the investigation, but the department “still has not learned any new information as to the whereabouts of Relisha Rudd.” Police did not reveal the man’s potential connection to the case and have blocked the video.

Police released the video after they completed an exhaustive search of Kenilworth Park and Aquatic Gardens last week. Police Chief Cathy Lanier said there was strong evidence suggesting that Relisha’s body could be in the park. Police did not find her body there, nor did they uncover any clues as to where the missing girl could be. Lanier said at the time that “it is heart-wrenchingly frustrating that we don’t have answers to where she is.”

Relisha was last seen with Kahlil Tatum, who worked as a janitor at the homeless shelter where Relisha lives with her mother. On March 2, police say, Tatum purchased large trash bags and was spotted at Kenilworth Park soon after. On March 20, the dead body of Tatum’s wife was found in a hotel room in Oxon Hill during the search for Relisha. When searching the park for Relisha, police recovered the body of Tatum, who died of an apparent self-inflicted gun wound.
