A Michigan woman is facing serious criminal charges after authorities say she held her sister-in-law captive in a basement for years, depriving her of basic necessities and leaving her severely malnourished.

Tasha Beamon, 48, has been charged with unlawful imprisonment and first-degree vulnerable adult abuse, according to reports from Michigan Live and local broadcasters. Prosecutors allege Beamon was acting as the victim’s caretaker at the time of the alleged abuse.

The case came to light on March 15, when the 58-year-old woman managed to escape and seek help. According to authorities, she broke a window at a nearby home in Saginaw, prompting the homeowner to call 911. When officers arrived, the woman told them she had been held against her will in a basement for approximately two years.

Police say the victim described being rarely given food and having little to no access to water. She was immediately taken to a hospital, where she was treated for severe malnourishment.

According to court documents cited by WJRT, investigators who searched the home found disturbing conditions consistent with her account. In the basement, officers reportedly discovered a mattress on the floor, a bucket filled with urine, and a locked door.

Authorities classified the woman as a vulnerable adult, a designation that applies to individuals who may be unable to care for themselves due to physical or mental limitations.

Following the discovery, investigators questioned Beamon and quickly moved forward with charges. Details about a possible motive have not been publicly disclosed, and it remains unclear whether Beamon has entered a plea or retained legal representation.

Beamon is currently being held at the Saginaw County Jail on a $100,000 bond as the case proceeds.

The investigation remains ongoing.
