"I absolutely do believe that there's gonna be some other folks brought into this investigation," said Osceola County Sheriff Russ Gibson. "It's just a matter of time before they're identified."

Detectives said Nicholas Rivera was arrested after information was obtained during the ongoing investigation into Montalvo's death.

Gibson said Rivera was also living on the property at the time of the murder.

The U.S. Marshals Service and the Coweta County Sheriff’s Office in Georgia assisted Osceola County deputies with this arrest.

Officials are still trying to determine Montalvo's cause of death. Her estranged husband, Christopher Otero-Rivera, is set to make an appearance in court Tuesday.

Anyone with any information on this case is asked to call the Osceola County Sheriff’s Office at 407-348-2222.
