Officials refuted previous reports that August was beaten, saying "there is absolutely no evidence that supports that theory"
Authorities in Alabama said that no criminal charges will be filed in the case of a teen football player who sustained serious injuries at his high school over the summer, which they determined to be the result of a "freak unfortunate accident."
August Borden was airlifted to the hospital after the incident at school on Aug. 19, which left him with a serious concussion, orbital fractures underneath each eye and a fracture in his skull behind his sinus cavity, his parents previously told PEOPLE -- adding that their son had "no recollection" about what happened.
In a previous statement provided to PEOPLE, Robert Bissell, director of federal programs for Tuscumbia City Schools, claimed that the incident occurred while players were walking from the weight room to the locker room after a workout. Afterwards, school employees immediately called 911 and coaches began CPR.
In a press conference earlier this week, Madison County District Attorney Robert Broussard said that "we've learned that this is, more or less, typical high school banter and some limited physical contact involved, with no malice, no anger involved among any of the students, and a freak unfortunate accident that resulted in the injured student's injuries."
"This case is closed as far as the criminal justice system goes," Broussard added. "We uncovered no evidence that would support any kind of criminal charges in this matter."
Broussard's office did not immediately respond to PEOPLE's request for additional comment.
At Wednesday's press conference, Madison County Chief Deputy District Attorney Tim Gann provided more details about what happened that day.
According to authorities' findings, August and another football player, whose relationship to each other was described as cordial, were leaving a workout facility while laughing and talking.
As they were walking, the other football player, who was not identified by name, went behind August and gave him a "bear hug." According to a witness, August coughed and made a weird sound, and then the other player let go of him, "thinking that something wasn't right," according to Gann.
Then, for an unknown reason, Borden passed out, Gann said, noting that witnesses said that while he was going down, his foot slipped off a 6-inch tall landing on a set of stairs, sending him tumbling towards his left side.
"At this point, he is completely unconscious, he cannot protect himself," Gann told reporters. "He is falling full force with no hands or no anything to protect himself...His upper body goes forward extremely hard, and the first thing that hits is the side of his face and the front of his face....He goes into a seizure and his having those symptoms consistent with a severe concussion."
That was when first responders arrived to stabilize August, who was later airlifted to the hospital, Gann continued.
He went on to refute previous reports that August suffered a beat-down by other students, saying, "There is absolutely no evidence that supports that theory."
Broussard said that multiple students, faculty and other individuals were interviewed as part of the investigation, describing them as being forthcoming and transparent. Asked about their conversations with Borden himself, officials said they had last spoken to the teen the previous week and that he still had no memory of the actual incident.
Speaking with AL.com, August's father, Jason Borden, said that he questioned the official findings about what happened to his son.
"When you look at the photos and all the evidence that we have, to come out and say that there was absolutely no foul play involved and it's just a total freak accident, it doesn't line up to me at all. It doesn't," he said. "It's very shocking."
In a statement provided to PEOPLE, lawyers representing the family said that "they continue to seek truth, accountability, and transparency in the pursuit of justice for their son."
"The family's goal has always been -- and will continue to be -- to find answers. They are committed to ensuring that August's story is met with honesty and integrity at every stage of the process," wrote attorneys Kristin K. Stamps and Shane Sears.
"They remain profoundly grateful for those who continue to support August's recovery and stand beside them through this ongoing journey," they added. "Please continue to keep August in your prayers as he works through a long and challenging road ahead."
Kristen Van Devender, August's mom, previously told PEOPLE that she was about to leave to pick her son up from practice when a football mom contacted her, telling her she needed to get her son.
Kristen raced to the school and found an officer waiting for her as well as firetrucks and an ambulance. "It was chaos," she said. "A living nightmare."
Her husband Drew, August's stepfather, was called to the scene to help calm her down and said that he was told that August "had a fall" and to "just get here now."
Despite what the family claims they were told by the school, they previously alleged doctors said that their son's injuries were not consistent with "a fall."
Asked about those comments during the press conference, Chief Deputy District Attorney Gann said that while Borden's injuries were "consistent with an assault" in terms of their severity and location, their investigation showed "that was not the case."
Gann went on to say that although the family was "disappointed" their office was not pursuing any charges, he felt like they were "receptive to the information they were given."

Although the D.A.'s probe into what happened to Borden has come to an end, Tuscumbia City Schools Superintendent Russ Tate announced that the district's internal investigation remains ongoing, according to a statement obtained by PEOPLE.
"As explained during our September Board meeting, we are working with our recently hired outside legal counsel to complete an internal investigation into this matter," Tate said. "With the law enforcement portion of this investigation completed, our attorney can continue with his investigation without risk of inadvertently interfering with law enforcement's investigation."
"While this has been a difficult time for our school community, we remain committed to seeing this process through to its conclusion," Tate continued. "We will continue to support all of our schools and students, and we thank our community for its continued support as well."
Their investigation will likely take weeks to complete, after which their findings will be turned over to the board.
