D.C. Police need the public's help in finding a 43-year-old man who was last seen on July 13 and a 34-year-old woman who was last seen on July 16.

Keith Johnson, 43, was last spotted in the 1800 block of Tobias Drive in Southeast, police said.

Police later found Johnson's car on the 3700 block of D Street in Southeast. D.C. Police Chief Peter Newsham said the car was found with a "significant amount" of blood inside. He said officers were able to recover Johnson's wallet from the vehicle and have not seen any activity in his bank statements.

?We are fearful that he may have been injured,? Newsham said during a news conference Thursday afternoon.

This has led police to believe Johnson is critically missing.

Officers have searched the area of Anacostia Park and will continue to search other areas nearby, Newsham said.

Johnson is described as a black man with a medium brown complexion, brown eyes and mixed gray hair. He is 6'1" and weighs about 210 pounds, police said.

Johnson was last seen wearing a purple shirt, jean shorts, gray and white sneakers with a black hat.
