42-year-old Brent Cox and 40-year-old Tammy Schreiner were arrested in Fresno, along with Brent’s wife, Jillian Cox, in February 2021.

The sentences were handed down by Judge David Gottlieb after they both pled guilty to several felony sexual assault counts.

Judge Gottlieb overruled the jury’s requested term of 38 years in state prison for Brent Cox.

Cox began sexually assaulting the minor beginning around May of 2020 with the knowledge of her mother, who was also Brent’s live-in girlfriend.

Brent Cox was also married to Jillian Cox who also lived in the house on E Princeton Ave. near Blackstone and Shields in Fresno.

Jillian Cox pled guilty and was sentenced on January 6th to serve one year in county jail and 4 years felony probation.

The Fresno County District Attorney’s Office says the three adults were in a long-term three-way sexual relationship and conspired to groom Schreiner’s daughter to be Brent Cox’s “third wife”.
