Police have released a sketch of a man who may be involved in the disappearance of a 25-year-old Michigan mom.
Jessica Heeringa was last seen Friday at the gas station where she worked.
Police are looking for this man, who was driving a silver minivan seen near the station that night.
A witness says he saw the suspect approach Heeringa and try to flirt with her.
Shortly after another witness called 911, saying the station seemed to be abandoned.
