Conditional Release
Geyser had been granted conditional release from the Winnebago Mental Health Institute earlier in 2025 after a judge determined she no longer posed a threat to herself or others, concluding that she had made significant progress in her mental health treatment.
Geyser was committed to a psychiatric institution for up to 40 years after being found not guilty by reason of mental disease or defect for the 2014 attempted murder of her classmate, Payton Leutner. She had been living in the group home as part of her supervised release plan.

Legal and Rehabilitation Concerns
Geyser, 23, will now likely face a court hearing regarding her violated release conditions. Legal scholars suggest that violating a release plan and removing a monitoring device will typically result in the court revoking release and potentially ordering a return to a more secure mental health facility where her freedom would be more limited. The victim’s family, through a spokesperson, confirmed they were safe and working with law enforcement during the search, expressing gratitude for the efforts to apprehend Geyser.
