He was arrested and charged with 32 counts of enhance possession of child pornography and booked into a Polk County Jail, where he was being held on a $32,000 bond, the sheriff’s office said.

Christian Pillot-Osorio, 29, of Lakeland, had images on his phone showing children as young as 5 months old being sexually abused, detectives said. He allegedly told deputies had been watching child pornography since he was 16 years old adding that he used platforms like Snapchat to distribute child pornography. He is being held at the jail without bond.

Deputies also arrested Billy “Jordan” Rose, 23, of Winter Haven after finding images on his phone showing children as young as 2 years old being sexually battered, authorities said. They said Rose told detectives he used the Kik Messenger app to download child porn. He is being held in the Polk County Jail on $585,000 bond ($15,000 per charge). He faces 38 counts of child pornography.

Judd said more charges are expected once deputies exercise search warrants for the suspect’s various devices.
