>Chris Harper-Mercer - according to the Los Angeles Times, unnamed law enforcement sources described him as a "hate-filled" man with antireligious and white supremacist leanings, and with long-term mental-health issues.
On the day of the shooting, Harper-Mercer gave a survivor numerous writings showing he had studied mass killings, including the 2014 killing spree at Isla Vista, California. These expressed his sexual frustration as a virgin, animosity toward black men, and a lack of fulfillment in his isolated life.
>Nikolas Cruz - Police said that he held "extremist" views; social media accounts that were thought to be linked to him contained anti-black and anti-Muslim slurs, YouTube comments linked to him include "I wanna die Fighting [sic] killing shit ton [sic] of people", threats against police officers and "antifa," and intent to mimic the University of Texas tower shooting. Items recovered by police at the scene included gun magazines with swastikas carved in them. One student reported that Cruz had drawn a swastika and the words "I hate niggers" on his backpack. CNN reported that Cruz was in a private Instagram group chat where he expressed racist, homophobic, antisemitic, and anti-immigrant (xenophobic) views. He said he wanted to kill gay people and Mexicans, and talked about keeping black people in chains. He said he hated black people "simply because they were black," and Jewish people because he believed "they wanted to destroy the world." He also referred to white women who engaged in interracial relationships as traitors, he wore a MAGA hat, which he included in his instagram profile and was seen on video in his boxers and socks shooting a bb gun at buckets and bottles in his backyard while wearing the same hat and five of the victims killed were Jewish.
