A Florida father stabbed his 17-year-old twins inside their Orlando apartment before taking his own life, Orange County deputies say after a neighbor’s wellness check.
Orange County Sheriff’s Office detectives announced Friday that Ivan Montiel Roa, 63, killed his children, Carlo and Melanie Montiel Infantino, both 17, then died by suicide inside the family’s home at Courtney Chase Apartment Homes. Officials reported the teens’ bodies were found in the living room with multiple stab wounds; Montiel Roa was found dead in the master bedroom.
A concerned neighbor had not seen the family for about a week and called 911 for a wellness check. Deputies discovered the three bodies on Wednesday. Police did not say when they believe the killings occurred or how the father died.
The case leaves two teenagers dead at the hands of their own parent and no living defendant to face a courtroom. That pattern of family violence has appeared in other recent cases, including a Michigan father who killed his wife and six children before setting the home on fire.
Detectives stated their working conclusion in plain terms.
Orange County Sheriff’s Office investigators said in a news release:
"At this time, detectives believe Ivan murdered Carlo and Melanie and then committed suicide,"
The discovery did not start with a scream or a fight reported in real time. It started with absence. A neighbor noticed the family had gone unseen for roughly a week and asked police to check on them. That call brought deputies into the apartment and onto a scene of three dead residents.
Carlo and Melanie were found lying in the living room. Their father was found in the master bedroom. The teens had been stabbed multiple times. Authorities have not released a motive, a precise time of death, or the method the father used on himself.
Similar parent-against-child killings have drawn police attention abroad as well, including an Australian father who strangled his two young children in a Bali bungalow before hanging himself, according to police there.
Public records and local reporting fill in a short, grim lead-up. Montiel Roa’s wife, the twins’ mother, died in June. Her obituary said the family was from Venezuela. The mother’s full name was not released in the initial police account.
Montiel Roa listed himself as a realtor on Facebook. The Orlando Sentinel reported that a construction business tied to him was dissolved on Sept. 25. None of those facts amount to a proven motive. They do show a household that had already absorbed a major death and a business shutdown in the months before the bodies were found.
In December 2025, Montiel Roa posted on Facebook a line that tracked a famous film monologue: “Introduce a little anarchy, alter the established order and everything turns into chaos. I am an agent of chaos.” Reporting also described him reposting conspiracy material and “new world order” claims. Police have not tied that post to the killings, and no separate mental-health or criminal history was detailed in the Friday release.
Spousal and family murder cases often turn on private pressure that only becomes public after the fact, as in the trial of a former American Idol contestant charged with killing his wife while prosecutors highlighted a mass of messages to a mistress.
Florida Rep. Rita Harris, who lives near the apartment complex, issued a short public response focused on the loss and on the officers who walked into the apartment.
Harris said:
"There are no words that can make sense of a loss like this,"
She added:
"I am also thinking of the first responders and law enforcement officers who carry the weight of what they encounter in service to our community."
That second point matters. Deputies and medics are the ones who enter the quiet apartment after a wellness call and find children stabbed in the living room. They carry the images home. The public gets a news release. They get the room.
Early public stories about violent deaths sometimes race ahead of the evidence, a problem seen when a murder arrest in the Tasia Fortune case undercut sweeping outside claims about what had happened in Mississippi.
Large pieces of the file remain closed to the public. Authorities have not announced when they believe the stabbings and the father’s death took place. They have not described how Montiel Roa died. They have not named a motive. No case number or medical examiner ruling was included in the Friday announcement summarized in initial coverage.
What is established is narrow and hard: two 17-year-olds dead by stabbing in their own living room; their 63-year-old father dead in the bedroom; detectives’ belief that he killed them and then himself; a neighbor who finally called because the family had vanished from daily view for about a week.
Wellness checks are ordinary tools. Most end with a conversation at the door. This one ended with three bodies and a murder-suicide finding. Parents are supposed to be the shield. Here the parent was the threat, and the twins had no chance to grow past 17.
When a father turns a family apartment into a crime scene, the victims are the children who never get another ordinary day, and a community that has to trust police to sort the truth from the silence left behind.
