Christian Michael Muse was 19 and living in Fort Washington, Maryland, when he was last seen on July 15, 2012. That evening he left his home in the 6200 block of Dimrill Court after telling his father he would be back soon, but he never returned. A few days later his last known location was reported as the Glass Manor area of Oxon Hill, Maryland.

Known as Twin, Christian had several distinctive tattoos: the initials CM under his left eye, a bird on his neck, and the word Twin on one hand. He was wearing khaki pants and a short-sleeved shirt with black and white specks when he disappeared. His family believes he would not have left on his own accord, and some have suggested possible foul play, but the case remains unsolved.

If anyone in the Fort Washington or Oxon Hill area remembers Christian or has information about where he went after July 15, 2012, please come forward.
