TITUSVILLE, Fla. - Titusville Police are calling the bystander who shot a gunman who opened fire at a park full of kids on Saturday a "hero." On Monday, police said they aren't releasing the names of those involved and said the citizen who returned fire on the suspect won't be facing charges. 
 
 "He's a hero," Titusville Police Sgt. Bill Amos said. "This park was filled with families and children and, at that time, it was an active shooter situation for him and he was trained enough to deal with it and he did." 
 
 Police said the incident started Saturday around 5:30 p.m. when the accused gunman got into a fight with someone else at the Peace in the City rally at Issac Campbell Park. Amos said the fight started because of a dispute over a basketball game. 
 
 The gunman opened fire at the park filled with families, Amos said. The shooting was caught on camera by DJ Dwight Harvey who streamed the event on Facebook. In the video, children are seen running from bounce houses, screaming, losing their shoes as they ran. 
 
 Amos said that by confronting the gunman the bystander saved lives, adding that the citizen had his concealed weapons permit. 
 
 "(The suspect) was confronted by a concerned citizen who saw him running away with the firearm and confronted him and (the suspect) pointed the firearm at him so that concerned citizen took action into his own hands and shot the perpetrator," Amos said. "It's a miracle. That's all you can say." 
 
 The shooting happened at the Peace in the City rally, hosted by the family of Tony Butler, 38, who was found murdered in a burning car in Mims back on July 9. 
 
 On Monday, Butler's aunt Brenda Mayo explained how painful it was for their family to have a shooting at an event she said was intended to bring peace to Titusville. 
 
 "We have to pull together to try to get peace back in the city, we have to do our best to pull together and it's scary because the younger generations all they want to do is to own guns, it's scary," Mayo said. 
 
 Like police, she said she is grateful for the bystander who stopped the shooter. Mayo said she knows him but for privacy reasons, would not name him. 
 
 "I thank God he was there, I hate he had to do that because I know it's bothering him as well," Mayo said. 
 
 Titusville Police said Monday that the suspect is in critical condition. They expect to release reports of the shooting and 911 calls later this week.

 Titusville Police are investigating a shooting Saturday at a crowded park that was stopped when an armed bystander shot the suspect, a department spokeswoman said. 
 
 A man involved in a fight with another person at Isaac Campbell Park left the scene and returned several minutes later, around 5:20 p.m., with a gun and opened fire on the crowd, police spokeswoman Amy Matthews said. 
 
 A bystander, who was licensed to carry a firearm, shot the suspect and waited for authorities to arrive, Matthews said. No other injuries were reported, she said. 
 
 The gunman, whose firearm was recovered from the scene, was airlifted to a hospital with life-threatening injuries, Matthews said. 
 
 “We are extremely grateful that nobody else was injured in this incident,” Deputy Chief Todd Hutchinson said in a news release. “This suspect opened fire at a crowded public park, this could have been so much worse”. 
 
 Titusville police are still investigating the incident, Matthews said. 
 
 Detectives consulted the state attorney’s office and no charges are expected to be filed against the bystander “as his actions were within the law based on the preliminary investigation,” Matthews said. 
 
 Anyone with information about the incident is asked to call the Titusville Police Department at (321) 264-7800 or CRIMELINE at 1-800-423-TIPS.

– It started with an argument during a basketball game—a game that took place at a crowded park that was hosting a rally to condemn violence. Police in Titusville, Fla., say a man left Saturday's Peace in the City gathering at Isaac Campbell Park, got a gun, then returned and opened fire, reports ClickOrlando. As kids and adults scattered for cover, police say a bystander with a license to carry a concealed weapon confronted the gunman and shot him. No one else was injured. "He's a hero," says Titusville Police Sgt. Bill Amos. "This park was filled with families and children and, at that time, it was an active shooter situation for him and he was trained enough to deal with it and he did." The man who initially opened fire is in critical condition, and no charges are expected to be filed against the unidentified bystander who shot him, reports the Orlando Sentinel. "It's a miracle, that's all you can say," says Amos. The rally was organized in honor of 38-year-old Tony Butler, who was murdered last month. Butler's aunt says it's distressing to have seen violence erupt at their rally, but she's grateful for the bystander. "I thank God he was there," she says. "I hate he had to do that because I know it's bothering him as well."
