A volunteer Bible class teacher at a Del City church has been charged with dozens of sex crimes after a 16-year-old girl told a Del City High School teacher that she felt like the man "brainwashed" her into having a sexual relationship.

The girl told police she was only 14 years old when she began a sexual relationship with Donnie Ray Schultz, 45, a man she befriended while attending his Bible class at Calvary Christian Church in Del City. She said the sexual relationship began in July 2014 and continued until November 2015. 

The girl reported numerous places where she and the suspect allegedly had sex, including the church, his home, her home, homes where he did repair work as a self-employed handyman, and even a storage unit in Oklahoma City. She told police that the suspect took pictures and video of some of their encounters.

FBI agents serving a search warrant allegedly found illicit images of the girl and suspect on his home computer and cell phone. 

Schultz was arrested on multiple felony sex crime complaints, including 19 counts of second degree rape, 31 counts of forcible oral sodomy, and one count each of manufacturing child pornography, possession of child pornography, and engaging in a pattern of criminal offenses in two or more counties. In addition to the state charges he faces, he may also face additional federal child pornography charges.

An official with the church said they were stunned by the allegations against Schultz. The church says he is a volunteer, not a paid staff member, and that the class he teaches is intended for adults. 

Church officials said that Schultz has been a member of the congregation for nearly 20 years, and he came to them at the recommendation of his previous church. It is important to understand that the church had to give him permission to attend, because at the time he came to the Del City church, he was a registered sex offender.

Schultz was convicted of second degree rape in  Cleveland County in 1995, and under the state's sex offender registration requirements at the time, he was required to register as a sex offender until 2013. 

When the federal government passed the Adam Walsh Act of 2006, states were required to assign one of three risk levels to everyone convicted of sex crimes. Level 1 sex offenders have to register for 15 years, Level 2 offenders for 25 years, and Level 3 offenders for life. Shortly thereafter, second degree rape (statutory rape) became a Level 3 sex offense in Oklahoma, requiring lifetime sex offender registration. 

Investigators believe there may be more minors involved in the case against Schultz, and say he could face additional state and federal charges as the investigation progresses.
