Daniel Hyden, a 44-year-old substance abuse counselor and author, has been charged with multiple felonies, including aggravated vehicular homicide and second-degree manslaughter, after allegedly driving intoxicated into a crowded park during July Fourth celebrations in Lower Manhattan, killing three people and injuring several others. Hyden's gray Ford F-150 struck 11 individuals, pinning four under the truck, three of whom died. Authorities reported that Hyden exhibited signs of intoxication and had a suspended license due to previous offenses. Hyden's ex-girlfriend and others revealed his long-standing struggle with alcoholism, which had impacted his personal and professional life. Despite his efforts to overcome his addiction and help others, Hyden has a history of violent behavior and previous run-ins with the law. The incident has deeply affected the victims' families and the local community, prompting strong emotional reactions during Hyden's arraignment.
