Suspect consumed 'conspiratorial' content online, investigation finds
Information provided to law enforcement shows that Robert Card appears to have "interacted with conspiratorial content" online.
Topics he engaged with included, but were not limited to, concerns about a financial crisis/stock market, LGBTQ+ issues, gun rights and commentary about Democratic public officials, including President Joe Biden.
It remains unknown whether any of his social media usage played any role in the suspect's decision to go on his rampage Wednesday night.
Law enforcement has not determined the motive, but they are looking into several aspects of the suspect's life, including his writings and history of mental health problems.
