FLORENCE, Ariz. — The Pinal County Sheriff's Office said it arrested 42-year-old Todd Brown, a sex offender who was found with thousands of files on his computer showing children being sexually abused and exploited, officials say.

PCSO said Brown admitted to detectives he downloaded and viewed the sexually abusive images, some which included infants and toddlers. 

Detectives said he also distributed images.

Brown has a history of failing to register as a sex offender after he was convicted in Washington state for the rape of a child, PCSO said.

He now faces 10 counts of sexual exploitation of a minor and a sex offender violation.
