LEWISVILLE, Texas - A former Denton church pastor and Lewisville ISD volunteer has been arrested and is facing charges relating to child pornography, according to jail records.

Jim Mustain Arrested

What we know:

Jim Dale Mustain, 64, was booked into the Denton County Jail on May 14.

Lewisville police said a warrant was issued for his arrest on April 23 for four counts of possession of lewd visual material depicting children. Then, on April 30, an additional warrant was issued for possession of child pornography.

Phone Sex Operator’s Anonymous Report

Dig deeper:

According to the arrest affidavit, an anonymous caller contacted the police and said she used to be a phone sex operator, and Mustain was one of her clients. 

The caller said the company created Skype accounts for the operators to talk to their clients. Mustain provided his real name and phone number on the Skype account. 

The caller said Mustain sent pictures of little girls fully clothed and expressed his fantasies of what he wanted to do to the girls.

The detective saw the photos provided by the anonymous caller, confirming they were all children, male and female, around 7 years old and younger, either clothed or in bathing suits.

The anonymous caller said she decided to contact the police after Mustain sent her a photo of what appeared to be a nude 6-year-old girl. She conducted an internet search for him and found a nonprofit website that suggested he had interaction with children in schools, and that concerned her.

Lewisville police obtained warrants to confiscate and search Mustain's electronic devices. During the search, they found "multiple offensive images" on Mustain's laptop, the affidavit states.

Prior Family Reports

Dig deeper:

According to the affidavit, detectives also learned that a family member reported Mustain two years ago.

The family member told police Mustain had images of children, mostly young girls, roughly between the ages of 6–10 years old, in underwear or wearing outfits such as swimsuits and dance leotards, on his iPad. 

The affidavit states that investigators believe Mustain would find images online, even from social media pages, of people he personally knows or takes them when he is at school. Mustain would later use those images to masturbate with them. 

At that time, there appeared to be no evidence of a crime, and the report was closed. 

Former Community Pastor

What we know:

The Preston Trail Community Church confirmed Mustain is a former employee. He served on the church’s staff as a community pastor from 2019 through 2023.

"Immediately upon learning of the allegations, we retained a third-party law firm to conduct a thorough, independent investigation. We are grateful to report that the investigation found no evidence of any illegal activity by him while employed at Preston Trail," said Senior Pastors Jim Johnson and Paul Basden in a message to the congregation on the church's website.

Church executives said there is no indication at this point that any children connected to the church were involved or harmed. Mustain's role did not include direct responsibilities to children or student ministries, they said.

Lewisville ISD Volunteer

What we know:

Lewisville ISD confirmed Mustain was involved in programs on Lewisville ISD campuses for several years. 

Most recently, he interacted with small student groups at Durham Middle School and Creekside Elementary School.

He is no longer allowed on any campuses, and the district has reached out to the families of students who may have had contact with him.

While the district said there’s no indication any Lewisville ISD students were involved, anyone with questions or information is urged to contact the Lewisville Police Department.
