JACKSONVILLE, Fla. – A Jacksonville man was killed and two teens were wounded Friday in what officials are calling a gang-related shooting that unfolded as fans left a Raines High School football game.

The Jacksonville Sheriff's Office said Joerod Jamel Adams, 19, was found dead at the scene and two teenagers, a 16-year-old girl who attends Lee High School and a 17-year-old boy who attends Raines High School, were wounded but are expected to survive.

Homicide detectives said the two teenage boys have known ties to criminal street gang members and attended the game together. Police said the two teenage boys were direct targets in the shooting and the teenage girl appeared to have been hit by a stray bullet and was not with the other victims.

The triple shooting happened about 10 p.m., about 15 minutes after the game between the Vikings and the Lee High School Generals ended at the school off Moncrief Road West in Northwest Jacksonville.

School District Police Director Micheal Edwards said the shots were fired near a sidewalk, close to where officers had checked everyone entering the gates into the stadium with a metal detector. He said because there were more than 50 police officers at the game, there was an immediate response.

The surviving teenage boy was found with a bullet wound to the upper body and the 16-year-old victim was shot in her lower body. Their conditions are listed as stable.

"The bullets was going this way. Everybody was running," said Leroy Mobley, a Vietnam veteran who heard multiple gunshots as he was leaving the game.

Dr. Diana Greene, superintendent of Duval County Public Schools, told reporters what happened was "unacceptable."

"This is a community issue," Greene said. "I need parents, students to stand up. If you see something, say something."

Greene said she and school district officials would be meeting Saturday to determine what changes need to be made to ensure the safety of all students.
