The FBI said Den Hollander was the primary subject in the attack and confirmed he had been pronounced dead but provided no other details. In writings posted online, Den Hollander derided the judge as having traded on her Hispanic heritage to get ahead. Den Hollander was best known previously for unsuccessful lawsuits challenging the constitutionality of ladies night promotions at bars and nightclubs. Den Hollander filed for bankruptcy in 2011, citing more than $120,000 in credit card debt, as well as rent and other expenses. In the filing, Den Hollander estimated he made about $300 a month from his work, with the bulk of his income coming from a $724 monthly Social Security payment.
