Summary based on the NamUs case record (MP22727) and 10 other sources
On a day in the late winter of 1999, a 46-year-old woman named Betty Sissac from Chicago, Illinois, went missing and has not been seen or heard from since. On March 27, 1999, Betty was reportedly with her friend's boyfriend. Another account states she was with her own boyfriend, Donald Williams, at the time she vanished. That day, she had dropped her child off at a friend's home. Betty never came back to get her child, which was out of character for the devoted mother. The last time anyone saw her, she was wearing a black leather jacket, black pants, and white Eagle brand sneakers.

Betty is a Black female with black hair and brown eyes. At the time of her disappearance, she was 5'6' and weighed around 130-143 pounds. A notable and distinctive physical characteristic is that she is missing a thumb or a finger on her left hand, which had been surgically removed. Her case was taken by the Chicago Police Department, and her information was entered into national databases for missing persons. The Cook County Sheriff's Office also lists her as a missing person.

Years have turned into decades, yet there have been no solid leads to explain what happened to Betty Sissac. The details surrounding her disappearance remain sparse, leaving her family with unanswered questions and a void that cannot be filled. The investigation into her disappearance remains open, a cold case that serves as a painful reminder of the day she vanished. The circumstances of her case are a somber overview of a life interrupted, a mother who never returned, and a mystery that has endured for over two decades.
