Amanda Wallace-Hubbard, the daughter oftransgender killer Robert Dorgan, has provided new details regarding her father's rampage motives in a phone interview withWPRIon Tuesday. According to her, Dorgan's hockey arena attack was driven by a vendetta against his family, especially herself and her sons.

'I just want to make sure people understand this was one person's vendetta against their family,' She said. 'We were targeted. This was very specific. It wasn't random.'

Dorgan, who identified as Roberta, reportedly fired — using a Glock 10mm and a SIG Sauer P226 — at his ex-wife, Rhonda Dorgan, who died at the scene, and one of their sons, Aidan Dorgan, who died in hospital.

Others involved in the fatality include Dorgan's ex-wife's parents, Linda and Gerald Dorgan, who have the same last name as him, and Thomas Geruso, a family friend, as reported by Pawtucket Chief of Police Tina Goncalves.

However, while these were exposed toDorgan's attack, they are yet alive and remain in critical condition at Rhode Island Hospital as of Tuesday afternoon. Colin Dorgan, another of Dorgan's sons with his ex-wife, was also in the arena at the time of the attack but managed to flee the rink unharmed.

Dorgan, who Wallace-Hubbard described as 'very sick,' underwent a gender reassignment surgery in 2020, which resulted in a bitter divorce battle with his ex-wife in the same year.

According to reports, this feud was the most likely reason for Dorgan's vendetta attack on his ex-wife and their kids, as court documents reveal Rhonda Dorgan's reason for filing a divorce was 'gender reassignment surgery, narcissistic and personality disorder traits,' after which she allegedly claimed her divorce filing was due to 'irreconcilable differences.'

Dorgan's former co-workers corroborated Wallace-Hubbard's earlier comment on her father's mental health by citing a bad temper and occasions of screaming matches with others.

According to one co-worker, Dorgan wasn't always proud of his gender transition as he expressed mixed sentiments, which sometimes involved feelings of embarrassment.
