The Collin County Sheriff’s Office reported last week that Sean Day, 31, of Farmersville, and a custodian employed at Caddo Mills ISD, had been arrested on charges of possession of child pornography with “intent to promote.” Collin County detained him after a cyber tip, and Caddo Mills ISD fired him from his job. Day worked in a district warehouse and had no role in supervising students at Caddo Mills.
