Police have identified the 82-year-old man who opened fire on a family at their Florida home – killing a father and his 11-year-old daughter – before dying during a gunfight with authorities. 

Guy Alexander Hansman, 55, and his daughter, Harper Hansman, were fatally gunned down by their neighbor – identified by investigators as Ronald Delserro – at their Port Lucie home on Monday. 

The Port St. Lucie Police Department shared that the killing spawned from a March 4 altercation where Delseroo’s bull mastiff attacked a woman living inside the victims’ home. 

Officers said that a judge had determined on Monday that the dog was dangerous, and said Delserro went to confront his neighbors. 

It was also revealed that Harper dialed 911 to alert cops that her parents had been attacked before being shot herself.

Police arrived to the scene on the block of 2500 block of Southeast Morningside Boulevard on Monday and exchanged fire with Delserro. He was armed with two pistols, WPTV reports. 

Delserro was found dead inside the home by a SWAT team. It is unclear how he died.  

‘I believe this to be an intentional act of violence against these neighbors,’ Port St. Lucie Assistant Police Chief Richard DelToro said on Monday. ‘It’s tragic. You can’t rationalize irrational behavior.’ 

Friends and loved ones shared photos of the two victims in tributes posted on Facebook, with neighbors initially posting photos of Harper.

Investigators were still processing the scene on Tuesday. Port St. Lucie Animal Control arrived at around noon on Tuesday to retrieve the dog.

Authorities rushed to a home in the 2500 block of of SE Morningside Boulevard in Port St. Lucie shortly at around 12.30pm when Harper called 911 and said someone was shooting at her parents.

‘If you heard this 911 call it would make the hairs on your neck stand up. A little girl calls 911 and says there’s someone shooting in our house, I think our parents are dead. I think our family is dead,’ said St Lucie County Sheriff Ken Mascara. 

He said officers found the adult male victim already dead in the garage, and added the 11-year-old girl was critically wounded and later died at a hospital.

At least two other victims managed to escape the house and were transported to the hospital. Their conditions are unknown. 

A contractor said that he saw the gunman’s wife just after the gunfire happened. 

‘She said, I hope he didn’t do something stupid,’ Ray Layfield said.

The shooting appeared to stem from a dispute over the dog, Port St. Lucie Police Department Assistant Chief Richard Del Toro said.

‘The dog was declared dangerous today in court, and he owned the dog and he went over there to confront his neighbors and this is what happened,’ Del Toro said, according to Treasure Coast Newspapers.

Authorities said a Port St. Lucie police officer also suffered a gunshot wound to his arm in the shooting. He is expected to recover.

‘Our officers encountered the suspect inside the victim’s home,’ Del Toro said. ‘Our officers and a deputy, actually, who was working at the school across the street responded to the scene immediately and exchanged gunfire with the suspect.’

According to police, the gunman barricaded himself inside the victims’ house for two hours before a SWAT team entered the residence and found him dead in a second-floor bedroom, reported CBS12. 

‘It’s shocking and tragic. It’s not characteristic for this neighborhood or the city, but we are going to do everything we can to find all the reasons why,’ Del Toro said.
