OSCEOLA COUNTY, Fla. — The father-in-law and the estranged husband of a woman who was found dead near St. Cloud days after she was reported missing face murder charges, the Osceola County Sheriff's Office said.
Sheriff Russ Gibson confirmed Sunday that Nicole Montalvo's remains were found Friday on the property near where her estranged husband, Christopher Otero-Rivera, and her father-in-law, Angel Luis Rivera, live.
Gibson said Otero-Rivera and Rivera were charged with premeditated murder. Both were previously named persons of interest in the case and arrested on unrelated charges Friday.

Deputies had searched the property on Hixon Avenue since Montalvo was reported missing Wednesday.
Montalvo's family said she had not been seen since she dropped her son off with her estranged husband on Monday and failed to pick him up from school Tuesday.
Gibson said Sunday afternoon that the search for Montalvo had come to an unfortunate end.
"Our investigation is now switching gears from a missing persons case to a murder investigation," Gibson said.
The Sheriff's Office also continued searching a second property Monday on Henry J Avenue, which is several blocks away from Hixon Avenue. Deputies said both properties belong to the Rivera family.

A judge denied Otero-Rivera bail during a Monday afternoon hearing. He is also charged with violating a no-contact order and his probation.
According to the public defender, he sent a text or phone call to Montalvo. He was not allowed to contact her in any way after pleading guilty to beating her and holding a knife to her neck with the help of another woman.
Rivera, Montalvo's father-in-law, has not appeared before a judge because he is in a hospital, suffering from chest pains and shortness of breath. He was initially charged with violating conditions of a registered felon.
Records said investigators discovered a Powerade bottle filled with 75 rounds of ammunition in a dresser in Rivera's bedroom.
Friends and relatives held a candlelight vigil for Montalvo at 7 p.m. at Lakefront Park in St. Cloud.
