APOPKA, Fla. — An 11-year-old boy charged with attempted second-degree murder in connection with the shooting of two 13-year-olds Monday night after a Pop Warner football practice remains in custody after a detention hearing Wednesday.

Another hearing is scheduled later this month.

Apopka Police Chief Michael McKinley said at a news conference Tuesday that the shooting took place at the Northwest Recreation Complex.

The firearm — which has been recovered — was pulled from an unlocked box in a parent's car, McKinley said. The 11-year-old was booked into the Juvenile Assessment Center following his arrest, he said.

The names of the 11-year-old charged and the two victims have not been released. 

"We shouldn't have 11-year-olds that have access to guns and think that they can resolve a dispute with a firearm," McKinley said, adding that, "it's a sad day when an 11-year-old can gain access to a firearm."

"As a society, we need to reflect on this. We see this way too often in our society now," he said. "Juveniles, young juveniles — and they're getting younger every day —  that have access to guns. But the more disturbing part is that they believe that that gun, that firearm, is a resolution to their problems.

"And it's not a resolution to anybody's problems. It just creates more problems for everybody involved ... they're ruining their lives when they're making these bad decisions to use a firearm to end a dispute."

In a press release, authorities said they received the report of a shooting at 8:20 p.m., and officers arrived four minutes later.

Investigators believe that the three juveniles were at a Pop Warner football practice when they got into a physical altercation, McKinley said. One of the juveniles allegedly grabbed a gun from his parent's car and shot the two others with a single shot, he said.

One was hit in the elbow and the other in the torso, police said.

Both were taken to the hospital, where one was released Monday night, while the other remains hospitalized after undergoing surgery, McKinley said. That youth is listed as stable, he said.

Surveillance video of the incident is available and will be released later, McKinley said.

More charges could be coming against adults, McKinley said, noting that it is a crime to allow children to have access to a firearm in an unsecured box.

"To all the parents out there, you have a firearm in your car, a firearm in your house, you have a responsibility to make sure that firearm is secure and ... not accessible to your children, because it only takes one bad decision in a split second to ruin their lives," he said.

McKinley said Monday's shooting was an isolated incident, and pointed out that the Northwest Recreation Complex is visited by thousands of people a day, and he could not remember another violent incident like this.

In a letter to parents posted on Facebook, the Apopka Pop Warner Board announced that practice Tuesday is canceled and that a meeting would be held with parents Wednesday.

"We are deeply saddened by this event, and our thoughts and prayers are with the families affected," the letter said. "We want to assure you that we are taking all necessary measures to ensure the safety and well-being of our participants. We are working closely with law enforcement officials to investigate the incident."

Counseling services will be made available to students who need them, the letter said.
