John Tiffin, 30, was booked into the Tulsa County Jail early Wednesday on a first-degree murder charge after his mother, Karen Curthoys, died, according to NewsOn6.
An arrest affidavit places the incident in October, when Tiffin was borrowing Curthoys' car and she wanted it returned, News On 6 reports. Authorities said she confronted him about the vehicle.
Investigators allege Tiffin struck Curthoys with the car in a driveway, pinning her between two vehicles. She was taken to a hospital and died several days later, as reported by NewsOn6.
Her obituary gives October 12, 2026, as the date of her death. The booking came Wednesday, November 11.
Tiffin remained in custody at the Tulsa County Jail, and bail was set at more than $500,000, NewsOn6 reported.
What happens after booking?
For people who do not obtain release under the pre-set bail schedule, a Tulsa County District Court local rule calls for a first appearance within 48 hours of arrest, the court’s rule says. The court says criminal cases can include arraignments, pretrial hearings, preliminary examinations and trials. The available account does not establish which proceedings, if any, are next in Tiffin’s case, according to Tulsa County District Court.
