Peter "PJ" Hyman, Jr., 16, was killed in a shooting outside the mall just after 7 p.m. He later died at St. Joseph’s Hospital.

Detectives said an altercation occurred between two groups of juvenile males following a planned "slapboxing" event in the parking garage. Detectives learned that following the group's mutual involvement in "slapboxing," the juveniles shook hands and parted ways.

However, a short time later, individuals from both groups reunited outside of the Citrus Park Town Center Mall, and a fight broke out.

After an extensive and detailed investigation, detectives arrested Samuel Oquendo, 15, for his involvement in the fatal shooting.

Oquendo was arrested on Thursday night and is facing multiple charges, including murder in the second degree, minor in possession of a frearm, and carrying a concealed firearm.

“I’m proud of our detectives for their work and determination in finding the person responsible for this tragic act. Their dedication is bringing the individual responsible for this senseless act to justice," said Sheriff Chad Chronister. "There is no excuse for a teenager to have access to a weapon. It is our responsibility as parents to hold them accountable before it’s too late. Parents, please have those important conversations with your children. Make them understand the consequences of their actions, especially when it comes to firearms."

Spectrum Bay News 9 is including the suspect’s name in this report as he is being charged as an adult.

“This 15-year-old defendant will be facing adult charges because he made an adult decision with a firearm,” said State Attorney Suzy Lopez. “It breaks our hearts to see another young person lost to gun violence. We will stand with the victim’s family to ensure the person responsible for his death is held accountable.”
