FRESNO, Calif. (KSEE/KGPE) – A Fresno mother and her boyfriend have been sentenced for their roles in sexually abusing the woman’s 12-year-old daughter over the course of several months.

On Wednesday, a judge sentenced 40-year-old Tammy Schreiner to four years and four months in prison for helping her boyfriend, 42-year-old Brent Cox, sexually abuse her 12-year-old daughter.

“I just wanted to apologize for my part in these actions, apologize to my daughter, her family. I accept full responsibility for my part in this, everything I did,” Schreiner said in court before her sentencing. “I just hope that one day my daughter can forgive and trust me again.”

Cox was sentenced to 16 years and four months in prison for his involvement in the crime.

He apologized to the court before he was sentenced.

“I understand what I have done,” said Cox. “I deeply regret what I have done. I apologize to everybody I hurt. The victim, the families and for my inappropriate behavior. I have a really deep hurt and regret in my life I won’t be able to fix and I hope one day to move on and get past this.”

The family of the victim doesn’t believe the apologies were sincere. 

“When Mrs. Schreiner walked into the courtroom, she pulled her mask down and smiled at Brent Cox,” said Deputy District Attorney Andrew Janz. “So I think they got a good deal and so they were happy about that and throwing in an apology at this late hour doesn’t make a difference.”

Officials with the Fresno County Sheriff’s Office said Schreiner, Cox, and his wife, Jill Cox, were involved in an open relationship with each other.

While all three of them were living in the same home, investigators said Schreiner and Jill began helping Brent groom the young girl, so he could sexually abuse her.

Officials with the Fresno County District Attorney’s Office said the three adults conspired together to groom Schreiner’s daughter to be Cox’s ‘third wife.’

Investigators said Cox had abused the young girl from June 2020 through January 2021.

The victim was granted a restraining order against Cox, and he will have to pay restitution.

Jill pled guilty and was sentenced on January 6th, 2022, to serve one year in country jail and four years of felony probation.
