Some observers of her post-arrest behavior have speculated that her assumption of different identities may have been the result of delusions or dissociation which arose from real trauma that she suffered as a child.
When she was discharged in October 1986, she was transferred to the Lena Pope Home for Troubled Girls, a residential treatment center in Fort Worth.
She said she was a teenager with an abusive background, lived in homeless shelters and foster homes, and enrolled in local high schools.
Throneberry also claimed that her Satanist father had raped her and killed her mother, and also accused her foster parents and other families that had taken her in of sexual abuse for which police could not find any evidence.
[citation needed] In 1997, when she was claiming to be 17-year-old "Brianna Stewart" (she was actually 28 at the time) in Portland, Oregon, and Vancouver, Washington, Throneberry falsely accused a 47-year-old security guard named Charles Blankenship of rape.
[9][11] Beginning in 1998, between the ages of 27 and 31, Throneberry posed as an initially 16-year-old Evergreen High School student named "Brianna Stewart", living in various strangers' homes around Vancouver.
Sympathetic benefactors gave her money and shelter, but she eventually betrayed their trust by making false claims of abuse.
Throneberry graduated from Evergreen High School as "Brianna Stewart" with the class of 2000 and enrolled at Clark College.
[10] In 2016, Throneberry resurfaced under the alias "Brianna Kenzie" and accused a local man of sexually assaulting her while she was working as a hotel employee.
