State and county Internet crimes officers say Zacarias is a part-time clown at children's birthday parties. They say he used his home desktop and laptop computers to exchange hundreds of child porn images.
Zacarias is charged with multiple counts of promoting and possessing a sexual performance of a child. He's scheduled for arraignment Wednesday.
Police say his computers are being examined and more charges might be filed.
Zacarias has been jailed. Jail guards say they can't forward telephone messages to him, and he doesn't have a listed home phone number.
