WAUSAU — Prosecutors have reached a plea deal with a paramedic and firefighter who resigned in 2017 from the Wausau Fire Department amid sexual assault allegations, according to court records.

An investigation against Clifford “CJ” Heiser began after a 29-year-old patient came forward accusing him of sexually assaulting her in the back of an ambulance. He was arrested Sept. 25, 2017 by Wausau police after they received DNA results that showed Heiser’s saliva on the woman’s breast.

Heiser was transporting woman to a local hospital when the alleged assault took place. The Wausau Fire Department placed Heiser on administrative leave when the investigation began. He resigned shortly afterward.

Heiser, a four-year veteran of the Wausau Fire Department, is facing charges of third degree sexual assault, fourth degree sexual assault and misconduct in office. A jury trial was set to begin Tuesday, Sept. 17 but those dates have now been taken off Circuit Judge Greg Huber’s calendar.

A plea hearing is set for this morning. Wausau Pilot and Review will update this story after Heiser’s court appearance.

Heiser remains free on bond.
