All suspects are presumed innocent until proven guilty in a court of law.
(Fremont County, WY) – 47-year-old Riverton man Jon Treadway pled both “not guilty” and “not guilty by reason of mental illness or deficiency” to all charges faced at his Tuesday, November 23rd arraignment hearing, overseen by the Honorable Judge Marvin Tyler.
Treadway was initially charged for two separate incidents, which resulted in three interference with a peace officer misdemeanor charges, one fleeing or attempting to elude police officers misdemeanor charge, one interference with a peace officer felony charge, and one escape from official detention felony charge.
During the hearing, Treadway informed Judge Tyler that he was currently taking medications that may affect his cognitive ability, and also referenced having suffered “a lot of head injuries” in the past.
After taking this into consideration along with Treadway’s “not guilty by reason of mental illness or deficiency” plea, Judge Tyler declared proceedings would be suspended in both cases until an order of evaluation can be conducted.
Further proceedings will continue or halt based on the results of the evaluation, which will be released in the forthcoming weeks.
Treadway was initially charged for the August 31st incident after he reportedly failed to yield for a traffic stop and fled law enforcement, ultimately having to be stopped with traffic spikes. When Treadway was transported to an area hospital, he reportedly became violent to the point that a taser was deployed.
Treadway was charged for the second incident on September 16th, when it was reported that he fled the Fremont County Justice Center after being informed that he was being arrested for a warrant. The pursuit resulted in a foot chase, CS gas (2-chlorobenzylidene malononitrile) being administered when Treadway wouldn’t come out of hiding, and a second foot chase that resulted the use of a taser and an officer sustaining a shoulder fracture.
