Deputies say they have arrested the teen responsible for shooting and killing 16-year-old Peter "PJ" Hyman last weekend at the Citrus Park mall. Samuel Oquendo, 15, was arrested Thursday night and charged with second-degree murder, minor in possession of a firearm and carrying a concealed firearm. 10 Tampa Bay is identifying the minor because, according to the state attorney's office, he will be charged as an adult. Detectives said two groups of boys met at the mall parking garage for a planned "slapboxing" event. After finishing "slapboxing," the boys reportedly shook hands and parted ways. But it didn't end there. Just after 7 p.m. Saturday, boys from both groups came back outside of the Citrus Park Town Center Mall and a fight broke out, the agency said. That's when Hyman was shot. He died a short time later at the hospital. Detectives said they gathered enough evidence to arrest Oquendo for his alleged involvement in the deadly shooting.
