He was able to shoot one cop in the arm and the chest, but a chest armor saved the policeman. Later, a SWAT Team was called to subdue the elderly gunman. When the SWAT team enters the second-floor bedroom of the Hansman home, they found him dead. No one knows how he died.

 After the deadly shootout that took Hansman's life, no more information was released.

The dispute was caused by a dog

The root cause of the problem was the dog of Delserro, who bit Mrs. Hansman when fending off attacks on her dog,Rucca. Records state that Delserro's dog that is a Mastiff, Roxy, was deemed a menace by the city's animal control office.

When this happened, it began a dispute between the neighbors that drew bad blood especially after his dog's overly ferocious nature that caused it to bite Mrs. Hansman.

It is said that the gunman's dog Roxy was not leashed and lunged at the smaller poodle, Rucca of the Hansmans. She sat on Roxy, who bit her instead.

Mrs. Hansman and Rucca were given medical aid due to Roxy's attack. Later, the dog was supposed to be quarantined, but it was taken when she reported the dog unleashed.

The hearing was done, and Roxy was deemed a dangerous animal on July 1. Delserro's dog was put to sleep on Wednesday just two days before he killed the dad and daughter.

Assistant Police Chief Richard Del Toro said Monday that the violence was intentional against the Hansmans. When he was interviewed by local station WPTV.  He added that all this violence was not fathomable.

One neighbor, Charles Dagata called the girl's death senseless over a dog, cited WPEC.
