Summary judgment in wrongful death, negligent security case involving the shooting of a 16-year-old.
Premises & Retail Liability
April 22, 2022
The plaintiff’s decedent was shot and killed while allegedly on his way home from school. We were able to prove that the young man was a trespasser on the common area of the property where he was shot, even though his aunt was a tenant in the apartment complex. The decedent’s family claimed he was on his way to see her. Our investigation revealed that he was connected to local gangs and that, at the time of his shooting, he was wearing a ski mask (in Florida) and carrying a hand gun.
