SHERMAN, Texas (KXII) - Law enforcement officials in Grayson County say a Denison pastor arrested for child pornography is being investigated for additional child sex crimes.
David Pettigrew, the pastor at Denison Church of the Nazarene and a substitute teacher at Sherman ISD, was arrested last week by the U.S. Department of Homeland Security (HSI) for the transportation of child pornography.
District Attorney Brett Smith says during the course of the investigation by HSI and the Grayson County Sheriff’s Office, they now have credible information Pettigrew may have acted in a sexually inappropriate manner with minors in the community. He says the behavior could range from sexual assault to inappropriate visual recordings.
“He also was a board member of a foster parent association as well as being a father of adopted children himself,” Smith said.
Pettigrew served as a crossing guard and cafeteria monitor at Sherman ISD from February 2016 to June 2017, and a substitute teacher at Neblett Elementary from January 2018 to February 2020.
“Mr. Pettigrew held positions of trust in our community,” Smith said.
His bio on the church’s website says he’s been the pastor there for 14 years.
We reached out to the church for comment, and did not hear back.
Sherman ISD said they are cooperating with the investigation, and in 2016 a fingerprint background check cleared Pettigrew to be hired as a public school employee. His last day at the district was February 25 of this year.
The Grayson County District Attorney’s Office and Grayson County Sheriff’s Office are asking for anyone whose child may have come into close contact with Pettigrew to talk to their child. Anyone who believes their child may have been a victim is asked to contact law enforcement.
