Santiago was arrested yesterday by US agents and Puerto Rico police. Puerto Rico police allege that the boys were sexually assaulted at Santiago's home in Ponce. Authorities say two of the boys were 14 and one was 12 years.
He faces federal charges of transporting minors with the intent to engage in criminal sexual conduct. It was not known if Santiago had a lawyer. The phone at the pastor's church went unanswered yesterday.
If convicted, he faces a maximum sentence of life in prison.
