Dugan, who identified as transgender, shot three of his children, his ex-wife, and one of their friends before killing himself, with his ex-wife and one of their sons being killed.

Dugan left behind an extensive social media history, including a post made the day before the shooting in which he responded to a post from actor Kevin Sorbo, who had referred to trans Delaware US Rep. Sarah McBride as a man, “keep bashing us,” Dorgan wrote, “but do not wonder why we Go BERSERK.”

A woman who claimed the shooter had been her father told reporters that he had "mental health issues." Dorgan had frequently posted jabs at his ex-wife on social media over the years of his transition.

Van Rootselaar then turned the gun on himself.

On Reddit, Van Rootselaar said that he was on the SSRI Sertraline, took the antipsychotic drug Risperidone on "rare" occasions for sleep," and smoked "a decent bit of weed."

As a minor, Westman changed his name from Robert to Robin, with the form stating that Westman "identifies as a female and wants her name to reflect that identification." In his manifesto, Westman expressed regret: "I am tired of being trans, I wish I never brain-washed myself."

Yet another section stated, "I finally found the answer—that changing one's gender is possible."
