Carlo and Melanie Montiel Infantino, 17, died with their father in a suspected murder-suicide in Orange County

 ORANGE COUNTY, Fla. — Carlo and Melanie Montiel Infantino, 17-year-old twin siblings and students at Cypress Creek High School in Orlando, died alongside their father in a suspected murder-suicide at a residence on Courtney Chase Circle. The Orange County Sheriff’s Office said deputies responded Wednesday, September 30, 2026, to the Courtney Chase Apartment Homes for a well-being check. Inside, deputies found the siblings dead in the living room. The welfare check brought deputies to the residence.

Investigators said their father, 63-year-old Ivan Montiel Roa, was found dead in the master bathroom. Based on preliminary findings, authorities believe Roa killed Carlo and Melanie before taking his own life. The sheriff’s office has preliminarily characterized the incident as a murder-suicide, but the investigation remains active. Authorities have not announced a confirmed motive or provided additional details establishing why the deaths occurred. The preliminary account does not establish every detail.

The loss has also reached the Cypress Creek High School community, where both siblings were students. Orange County Public Schools confirmed that school administrators had been notified about the deaths of two students and made grief counselors available to students and staff. The school response reflects the immediate need for support following the deaths of two teenagers who were part of the campus community. Counselors can help students and employees process the loss.

Florida State Representative Rita Harris, who lives near the area, also expressed shock over the deaths and emphasized the importance of support for students, families, and others affected. Her comments underscore the broader impact of a tragedy involving two young people, particularly within a community where classmates and school employees may now be processing grief while trying to return to ordinary routines. The broader community is confronting an unexpected loss.

A report cited by the South Florida Sun Sentinel said Roa, who was originally from Venezuela, had experienced significant personal and financial difficulties in the months before the deaths. Those reported circumstances included the death of his wife in June and the dissolution of his construction business on September 25. However, investigators have not established that either event was connected to the deaths, and no confirmed motive has been publicly announced. That distinction remains important while authorities continue their investigation. No connection between those events and the deaths has been confirmed.

For Carlo and Melanie’s classmates, teachers, friends, and loved ones, the circumstances surrounding their deaths do not define the entirety of who they were. They were twin siblings, teenagers, and members of a school community whose lives extended beyond the apartment where they died. Public information about their personal interests, accomplishments, and family life remains limited, making it important to avoid adding details that have not been confirmed. No connection between those events and the deaths has been confirmed.

As the Orange County Sheriff’s Office continues examining the deaths, additional information may emerge about the sequence of events and the circumstances leading to the tragedy. For now, the focus remains on the two young lives lost, the family members and friends left behind, and the Cypress Creek High School community facing their absence. Grief counselors and other support resources are available to affected students and staff as those closest to Carlo and Melanie begin navigating an extraordinarily difficult period of loss. Authorities may release information as the investigation develops.
