The human remains found on the St. Cloud property where Osceola deputies have been investigating have been confirmed as missing mom Nicole Montalvo, according to the Osceola County Sheriff’s Office.

Osceola deputies and investigators are also searching on a second potential scene on Henry J Avenue in St. Cloud, Gibson said.

Osceola Sheriff’s deputies have been digging in the woods beyond the house on the 5-acre property on Hixon Avenue, and also began to drain a pond behind the house Saturday but stopped as daylight faded. They commenced pumping again today.

“No matter how minute a role you may have played in this heinous murder, we are closing in on all of you. (To) every one of you, there is no rock you can hide under, no pond we can’t drain to find the evidence we need to substantiate a guilty verdict in this case,” Gibson said.

Montalvo was last seen at the home on Hixon Avenue on Monday night as she dropped off her son to his father and grandparents.

Authorities began searching the property on Thursday and within a day found possible human remains in the backyard.

Christopher Otero-Rivera, Montalvo’s estranged husband, and his father, Angel Rivera, were arrested Friday night on unrelated charges, and are considered persons of interest in Montalvo’s disappearance, according to the Osceola Sheriff’s Office
