FBI agents were investigating Joseph Sampson, another man accused of possessing child pornography, when they found messages between him and Richison from January 2024. Sampson allegedly asked Richison what the youngest child he'd been with was. To which he replied, a "buddy's foster son" who was 10 years old. Richison also said, "There's a guy in Henryetta that has a 3-4 [year old]," according to court documents. Richison was also reported to the National Center for Missing and Exploited Children tipline after a man, who was allegedly intimate with Richison, confessed to his partner that Richison had child sexual abuse material in his possession. On Dec. 4, 2024, Richison was arrested and FBI agents executed a search warrant at his home. Agents reported finding around 100 pictures and videos of children being sexually abused. The FBI said the children's ages varied but included some as young as infants. The investigation also found that Richison received at least one of the images while being employed as a teacher at Holdenville Public Schools. He had recently talked with a friend about becoming a foster parent, court documents said."It was a shock because nobody knew," Davenport told 2 News. "Even the district attorney didn't know they were coming to arrest him.""Student safety is the number one priority for our school district like it is for every school district," he said. "We try to ensure parents in our community that their children are safeguarded, and we want the very best for our students and our children and to have the best resources and staff to provide educational training for them."Davenport emphasized that the district is "fully cooperating" with the FBI and U.S. Marshals.2 News reached out to the law firm representing Richison for comment.
