Mercin Doenis Lucas Martinez was 14 when she was last seen in Canton, Mississippi, on October 22, 2016. She is described as Asian or Pacific Islander, with black hair, brown eyes, standing 4 feet 9 inches and about 125 pounds. The case was entered into NamUS on November 29, 2017, and the Madison County Sheriff’s Office is handling the investigation.

Early in the inquiry she was classified as an endangered runaway; investigators believed she may have left of her own accord and might still be in the Canton area. It has been suggested she could be using the name Mersin or the surname Martinez. Very few details about the circumstances of her disappearance or what she was wearing that day have been released.

Anyone who knew Mercin, saw someone matching her description in the Canton area after October 22, 2016, or has information about the names Mersin or Martinez in connection with a young woman is asked to come forward.
