Overview

  • Julia Hyman, a 27-year-old Cornell School of Hotel Administration graduate and Rudin Management associate, was among four people slain on the 33rd floor of 345 Park Ave.
  • The other victims included Blackstone executive Wesley LePatner, NYPD officer Didarul Islam and security guard Aland Etienne, and an NFL employee was wounded but survived.
  • Shooter Shane Tamura, 27, a former high school football player and Las Vegas casino security guard, left a note blaming chronic traumatic encephalopathy on the NFL for concealing concussion dangers.
