Valley registered sex offender arrested again for sexually assaulting 6-year-old

FRESNO, Calif. (KFSN) -- It was at a Porterville home where neighbors watched as 69-year-old Geronimo Sierra was arrested for the second time in one week.

"I was outside my house when I saw a bunch of cops outside," said a neighbor.

He didn't want to speak on camera but says the community was alerted to Sierra's registered sex offender status because of Megan's Law site -- prompting a serious discussion with his children.

"If they're playing outside I tell them to go to the left not to the right because that's where the house is," he said.

Porterville police say Sierra has a crime spree spanning almost 30 years.

"Dating back to the early 90's with convictions of attempted rape as well as indecent exposure," said Detective Sgt. Rick Carillo.

March 22nd, Sierra was arrested after exposing himself to a 10-year-old girl from within his home.

"She was in a vehicle waiting on her father who was in the area doing some work," Carillo said.

Carrillo says after bailing out, Sierra was arrested seven days later in connection with the sexual assault of a 6-year-old boy in 2002.

"It was on channel 30 they saw the indecent exposure arrest and a family reached out to me directly," Carillo said.

The allegations were first reported in 2016, but it wasn't until recent evidence was uncovered police arrested Sierra on seven felony charges.

Court documents show that same year Sierra was arrested for the attempted rape of a 17-year-old girl.

"It shows a history, it shows a trend of his acts, and there is still more investigating to be conducted," Carillo said.

As the investigation builds, police are calling on any other potential victims to come forward.

"When they have the courage to come forward we're here 24/7 to help in any way that we can," Carillo said.
