Brother-in-law of Nicole Montalvo arrested on charges of child porn

OSCEOLA COUNTY, Fla. - The Osceola County Sheriff's Office says the brother-in-law of Nicole Montalvo was arrested on eight counts of possession of child pornography.

Deputies say Nicholas Rivera as taken into custody in Newman, Georgia by The United States Marshals Service on Friday.

Officials say he is in the process of being extradited back to Osceola County.

Detectives say evidence for Nicholas Rivera's arrest originated from information obtained while investigating Montalvo's disappearance and death.

"We once spoke with him, and we were able to obtain his cellphone, and that’s how we got the information for the current charges of the child pornography,” said Osceola County Sheriff Russ Gibson.

Rivera's brother, Christopher Otero-Rivera, and father, Angel Luis Rivera, were both arrested and charged in the murder of Montalvo.

Investigators say Nicholas Rivera is considered a person of interest in Montalvo's murder.

Last week, Osceola County deputies also arrested Wanda Rivera, Nicholas Rivera's mother, on charges of providing false statements to investigators and tampering with evidence in connection with Montalvo's death.

The case has received massive attention from the St. Cloud community.

Hundreds of people attended a vigil for Montalvo last week.

“You hurt one of us, you hurt all of us,” Sheriff Gibson said.

Gibson calls the case one of the most gruesome he has seen in his career.

Because of that, he says he will personally ask prosecutors for the death penalty for those charged with murder.

“This is not something you can rush, this is something you need to take time with, to make sure we build such a solid case - such a solid case - that these people will not see the light of day to have another opportunity to hurt another one of our citizens,” Gibson said.
