Police have arrested a 34-year-old St. George man after confiscating photographs allegedly showing him raping an infant.

St. George police Lt. James Van Fleet said that Sergio Diaz-Palomino was held in Washington County Jail on Wednesday, where he had been booked on two first-degree felony counts of sodomy of a child and two second-degree felony counts of sexual exploitation of a minor.

Diaz-Palomino was arrested at his St. George home Tuesday afternoon after police were called to a Walgreens drug store, where a technician developing a roll of film had reported discovering the images.

"Walgreens reported that a couple of the photos had appeared to be pornographic, showing a [male] infant and an adult male. When our officers viewed them, they found them to be explicit to the point where Mr. Palomino appeared to be committing sodomy on an infant," Van Fleet said.

Palomino had used a different name on the photo processing paperwork, but was identified by store staff as having turned in the film to be processed. Police were able to locate him at his home near 100 East and 250 North and arrest him quickly, Van Fleet said.

During questioning, Palomino allegedly identified the person who had taken the pictures of him and the baby boy as being a woman he knew as the child's mother.

"We are trying to locate that person right now," Van Fleet said, but he declined to release the name. "We want to determine the welfare of that infant."

Van Fleet said Diaz-Palomino, who was being held on $42,000 bail, does not appear to have any past criminal record involving sex crimes against children.
