Her final hospitalization was involuntary, the siblings allege. They claim Miller contacted a mental health center and initiated the admission against his wife’s wishes.
According to her siblings, Mica was diagnosed with bipolar disorder while she was engaged to Miller, who reportedly took an active role in overseeing her care. They claim she was hospitalized multiple times during the relationship, including shortly before the couple married in 2017.
In a handwritten affidavit accompanying her divorce filing reviewed by Fox News Digital, Mica alleged that she had been abused "emotionally, sexually, spiritually, financially, and physically."
The family further said that while Mica was hospitalized, Miller took possession of her vehicle, phone and laptop. Her siblings said the computer contained intimate photographs of her. Mica later reported the alleged incident to police, according to the Netflix series.
Miller reportedly declined to participate in the documentary. Fox News Digital has reached out to his attorneys for comment.
The documentary relies on interviews with Mica’s relatives, friends, former Solid Rock Church members and divorce attorney, the streaming platform said.
Mica, 30, was found dead at Lumber River State Park in North Carolina April 27, 2024, two days after serving Miller with divorce papers.
The Robeson County Sheriff’s Office concluded that she died from a self-inflicted gunshot wound and closed its investigation. Miller has denied involvement in her death and has not been charged in her death.
He is, however, facing an unrelated federal prosecution over his alleged conduct toward Mica before her death.
A federal grand jury indicted Miller in December 2025 on charges of cyberstalking and making false statements to investigators, according to a South Carolina legislation, Bill 702, known as "Mica’s Law."
The legislation would recognize coercive control, including sustained psychological, emotional and financial manipulation, within the state’s domestic violence laws. The bill was referred to the state Senate Judiciary Committee but did not advance during the 2026 legislative session.
