SAN DIEGO -- A man accused of working with baby sitters who brought him children so he could molest them has been captured in Brazil.

The U.S. State Department says that Jared Yaffe was caught Monday by Brazilian federal police and brought back to the United States on Tuesday.

He was processed in Atlanta and was expected to arrive in California later Tuesday.

Yaffe is wanted in San Diego on 17 counts of child sexual assault and kidnapping.

The 30-year-old faces 100 years to life if convicted of all counts.

Authorities say Yaffe ran a child pornography ring by contracting with baby sitters to bring him children he eventually molested.

Yaffe was profiled on the TV show "America's Most Wanted" last month.

Police began investigating Yaffe after receiving a tip about the baby sitter's activities.

Officials said they believe the crimes occurred last year in Santee and El Cajon.

A search of Yaffe's home computer and cell phone turned up numerous photographs of children involved in sex acts, a prosecutor has said.

On Oct. 27, he boarded a flight from North Carolina to Frankfurt, Germany, according to the complaint.

Yaffe quit his job and completed an exit interview on Oct. 24, according to court documents.

Co-workers told authorities that Yaffe left because he had gotten into some trouble and would be in the state of Georgia, staying with his parents, according to the complaint.

Checks on Yaffe showed that he flew to Frankfurt. He later made his way to Romania. Federal authorities said they don't know why or how long he was there.

Yaffe departed for Brazil in late March.

The baby sitter, 24-year-old Aaron Zendejas, has pleaded not guilty to five felony charges, including kidnapping for oral copulation and lewd acts upon a child involving a 3-year-old boy.

If convicted, Zendejas could be sent to prison for 42 years to life.
