Investigators classified her case as an endangered runaway, and state that she may be in the local area. She has been known to frequent the East St. Louis, Illinois area.

Years after her disappearance, her mother found a notebook of Shemika’s. In one of the notes to a school friend, Shemika mentioned a boyfriend she thought may have gotten her pregnant.
