Shannon Nicole McClure was 23 and a mother when she was last seen in Sheridan, Wyoming, on June 15, 2013. Her husband and father-in-law reportedly dropped her off at a Walmart about 3 a.m.; she was said to be going to visit a sister who was actually out of town and unaware of any plans. Shannon left behind a young son and three stepdaughters and has not been heard from since.

Her disappearance is described as highly suspicious locally, and some community members have suggested people close to her, including members of her husband’s family, might know more; there has been no public confirmation of those suggestions. The family has raised concerns about the investigation and about a lack of cooperation from certain individuals close to Shannon. The Campbell County Sheriff’s Office continues to investigate.

If anyone knew Shannon’s whereabouts in June 2013 or has information about her movements that night, please come forward to investigators.
