Police in Washington, D.C., are working to identify a man as part of their investigation into the disappearance of 8-year-old Relisha Rudd.

According to MyFoxDC.com, police have released video of a man walking off an escalator at what seems to be a Metro station.

Police are asking for the public’s help in identifying the man, although it is still unclear how he may be connected to the case of the missing girl.

The video shows an African-American man wearing a dark hoodie, leather jacket, gloves and dark boots.

There is no timestamp on the video, according to the station, and police will not reveal where and when it was recorded for fear of compromising the investigation.

Kahlil Tatum, the man suspected of abducting Relisha Rudd, was last captured on camera on March 19 and 20 outside the Red Roof Inn in Oxon Hill, Md., where detectives say he killed his wife.

Tatum was then driven by a friend to the Southern Avenue Metro station.

It is not known whether the unidentified man in the video is the friend who drove Tatum to the Metro station.

The news of the video comes after Tatum was found dead last week at a park police had been searching in the hunt to find Relisha. Police reportedly said the cause of Tatum’s death was suicide.

Tatum was a janitor at the city homeless shelter where Relisha had been living with her family. The girl was last seen with Tatum on March 1. Her mother had given permission for Relisha to be with Tatum.

Police started searching for Relisha on March 19 following repeated absences from school. The next day, Tatum's wife was found dead from a gunshot wound to the head in the Red Roof Inn motel room. Prince George's County Police had issued a warrant for Tatum's arrest in connection with the death of his wife.

The day after Relisha was last seen, police say Tatum bought a container of heavy-duty trash bags, and was in Kenilworth Park for a period of time. After that, Tatum was going to work and was seen in D.C. through March 20, but Relisha was not seen.

Tatum was found dead in a building in the middle of the search area in Kenilworth Park and Aquatic Gardens.

Last weekend, police and fire department dive teams searched for evidence regarding Relisha, but nothing was found.

D.C. Police Chief Cathy Lanier called the search for Relisha in the park a recovery mission, but said authorities continue to follow new leads as they come in. Lanier said although the information is sometimes discouraging, authorities try to remain hopeful that Relisha could still be found alive.

If someone knows the man in the video, they are asked to call D.C. police at 202-727-9099. You can also send a text to the tip line at 50411.

The FBI is offering a reward of up to $25,000 for information leading to the location and return of Relisha Rudd. If you see her, call 911 immediately. You may also call the FBI at (800) CALL-FBI.
