ST. CLOUD, Fla. — The Osceola County Sheriff's Office is looking for a woman last seen in St. Cloud, and her disappearance is being called suspicious.

  • Authorities searching for missing Osceola mom Nicole Montalvo
  • Deputies found her 1999 Honda abandoned on Big Sky Boulevard
  • They're searching property on Hixon Avenue in relation to Montalvo

Nicole Montalvo was last seen Monday evening. Deputies say she was dropping off her 8-year-old son with his father and grandparents on Hixon Avenue in St. Cloud.

Deputies said Montalvo was supposed to pick up her son Tuesday from Harmony School, but she never showed up.

On Thursday evening, investigators began searching a five-acre property on Hixon Avenue they say is related to Montalvo. They also said they found her gold 1999 Honda, which was abandoned, on Big Sky Boulevard off Neptune Road. 

Her estranged husband, Christopher Otero-Rivera, is under probation and house arrest, according to deputies. They say he is not a suspect or person of interest at this time, but he's not cooperating with them, either.

Deputies also said Otero-Rivera has also had domestic violence issues with Montalvo in the past.

Montalvo was last seen wearing blue jeans and a gray shirt. Deputies said her cell phone has been turned off. 

If you know anything about Montalvo, you're asked to call the Osceola County Sheriff's Office immediately at 407-348-2222.
