Carlo and Melanie Montiel Infantino — Orange County Family Death Investigation

Case overview and investigative status

Deputies responded to a wellness check at a home in the 1200 block of Courtney Chase Circle in Orange County, Florida, on September 30, 2026. The Orange County Sheriff’s Office reported that twins Carlo Montiel Infantino and Melanie Montiel, both 17, were found deceased, and their father, Ivan Montiel Roa, was also found deceased. Detectives believe the father killed the teenagers and died by suicide. This is the sheriff’s preliminary investigative assessment, not a court verdict.

Victims and family

Carlo and Melanie were 17-year-old twins. FOX 35, citing the sheriff’s October 2 statement, reported that both were found with multiple stab wounds. No additional private family or school information is reproduced without an independent public-interest basis.

People involved and legal distinctions

The sheriff’s account identifies Ivan Montiel Roa as the person detectives believe killed the twins before taking his own life. Because he is deceased, no prosecution of him is anticipated. There are no defendants, defense lawyers, trial witnesses or sentencing proceedings to list in this case file.
