LAKELAND, Fla. – The Polk County Sheriff’s Office arrested 12 people, including two Disney employees, during an undercover child pornography investigation, authorities said.

The September operation, dubbed Operation Guardians of Innocence, focused on ending the promotion, possession and distribution of child pornography.

“We fiercely track down and arrest those who manufacture, collect, trade or distribute child pornography," Polk County Sheriff Grady Judd said in a news release. “Research has shown that the overwhelming majority of child pornographers, given the opportunity, have or would commit sexual acts upon a child.”

Judd said Miguel Ruiz, a 15-year Disney employee who lives in Davenport, downloaded and viewed files containing child pornography depicting children between the ages of 4 and 9 years old.

Judd said detectives seized computer equipment from the home, and during an initial preview of the equipment, located files depicting child pornography. Ruiz, 41, admitted to detectives that it was illegal to view the files, but attempted to delete any traces of the files, deputies said.

Judd said Ruiz also made sex dolls that resembled children.

"He has relations with this doll. All kinds of relations: verbal relations, sexual relations, perverted relations," Judd said while holding a photo. "He actually put this (doll) together for us. The guy is a nut."

Ruiz was taken into custody without incident and charged with three counts of possession of child pornography and promotion of child pornography.
