Davante Richardson, 28, went missing from a rural area near Greybull, Wyoming in July 2020.

He'd been living with his mother in south Washington, D.C., about a mile from the nation's capital.

In late July, Davante embarked on a cross-country road trip from the urban streets of D.C., to the remote expanse of Wyoming's high desert.

He hasn't been seen since, and his disappearance remains unsolved.

Anyone with information that may be relevant to this investigation may contact the Big Horn County Sheriff's Office at 307-568-2324, or Investigator Israel James with D.C. Metro Police at 202-727-9099.
