12/12/2025 UPDATE: Heather Dibert--Fawn Mountain's abusive former partner--was sentenced to nearly 15-40 years in prison on 12/12/2025. This sentencing was not related to Fawn's case, but rather, to a murder-for-hire scheme targeting another, estranged partner and several members of that partner's family. The judge who presided over the sentencing described Heather Dibert as "one of the most manipulative people I've ever seen in a courtroom."
