A Florida father fatally stabbed his teenage twins before taking his own life in a gut-wrenching double murder-suicide, according to police. Ivan Montiel Roa, 63, carried out the deadly attack against his children, Carlo and Melanie Montiel Infantino, both 17, inside their Orlando apartment, the Orange County Sheriff’s Office announced Friday in a news release.Officials said they discovered the grim scene – the two teens’ bloodied bodies with multiple stab wounds lying in the living room, and Montiel Roa inside the master bedroom –  on Wednesday after a concerned neighbor called 911 for a wellness check because they hadn’t seen the family in about a week.  “At this time, detectives believe Ivan murdered Carlo and Melanie and then committed suicide,” authorities said.Police did not reveal when they believed the horrific killings occurred or how the father killed himself.“There are no words that can make sense of a loss like this,” said Florida Rep.Rita Harris, who lives near the Courtney Chase Apartment Homes, where the family lived.“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.”According to public records, Montiel Roa’s wife and Carlo and Melanie’s mother died in June.

The family was from Venezuela, according to her obituary.  Montiel Roa was a realtor, according to his Facebook.He also had a construction business that was dissolved on Sept.
