Summary based on the NamUs case record (MP11955) and 13 other sources
In the late fall of 2002, Sierra Thomas, a 19-year-old mother known to her loved ones as 'Sweetie,' was focused on building a future for herself and her two young daughters, then aged two and four. She was a resident of Atlantic City, New Jersey, where she balanced motherhood with a job at Caesar's, a local resort hotel. Sierra had recently taken a significant step toward her personal goals by enrolling in an adult education program to complete her high school diploma. Friends and family describe her as a dedicated mother who was deeply committed to her children, making her sudden disappearance all the more perplexing and painful for those who knew her. They cannot imagine any reason why she would willingly walk away from her life and, most importantly, her daughters.

The last day Sierra was seen was November 21, 2002. That day, her sister gave her a ride to the 800 block of North Maryland Avenue in the Back Maryland neighborhood of Atlantic City. The purpose of the visit was for Sierra to see the father of one of her daughters. She told her sister she would call when she was ready to be picked up. After waiting in the car for about an hour, her sister went to a nearby store to pay some bills, but the call from Sierra never came. She has not been seen or heard from since that day. At the time she vanished, she was wearing a black Guess jacket, a dark blue or black shirt, light blue sweatpants, and a multi-colored scarf, and she was carrying only $33 in cash.

Accounts from that day indicate that Sierra’s boyfriend at the time was the last person known to have seen her. He reported seeing her with another male friend shortly before he met with her himself. Following that encounter, all contact with Sierra ceased. Her failure to return to her children, her job, or her classes was completely out of character. Law enforcement has stated that foul play is suspected in her disappearance. Despite the passage of years, the case remains unsolved, leaving her family without answers about what happened to the young mother. The investigation into Sierra Thomas's disappearance continues, a lingering story of a young life interrupted and a family left waiting.
