The recording started from the moment Dempsey's cruiser slowed near the park and captured everything that followed. It showed Dempsey approaching two teenagers who were standing in an open area of grass doing nothing that required any police response. It showed his first words to Austin.
It showed Chloe telling him Austin was her boyfriend and Dempsey asking whether she was being forced to say that. It showed Austin calmly asking what the problem was, and Dempsey telling him to shut up. It showed Austin reaching into his pocket with an ordinary movement and Dempsey lunging at him and driving him into the ground.
The footage captured Dempsey shouting that Austin was reaching for a weapon. It captured Chloe screaming. It captured Austin saying he was 17 and had done nothing wrong while his face was against the grass.
And it captured the phone, clearly visible in Austin's hand for a fraction of a second before Dempsey made contact. That established beyond any meaningful argument that what Austin had been reaching for was exactly what both Austin and Chloe had said it was.
The captain suspended Dempsey without pay that morning and referred the matter to Internal Affairs. He also contacted the city's legal department and told them to prepare for a lawsuit because one was coming, and the evidence was not on the department's side in any meaningful way.
Austin's family attorney had already filed formal complaints with the department, the state attorney general's office, and the city's civilian oversight board by the time the captain made that call. The complaints were specific and detailed and were attached to a demand letter outlining the lawsuit the family intended to file and the damages they were seeking.
Chloe's family filed its own complaint and its own demand letter the same day through a separate attorney.
When the two families' attorneys reviewed the body-camera footage and the drug test results together, the case they were looking at had become significantly stronger than either had anticipated when first taking the matter on. The racial profiling was documented. The force used against a minor was documented. The claim that Austin had been reaching for a weapon was directly contradicted by the footage.
The drug test also established that the officer who had made those decisions had been impaired while on duty, which raised broader questions about the department's oversight and its responsibility for allowing him to remain on patrol in that condition.
Internal Affairs pulled Dempsey's personnel file and found three prior complaints. The first had been filed two years earlier by a Black man who reported that Dempsey had stopped him without cause and had been aggressive and dismissive throughout the interaction.
The second had come from a Black family who reported that Dempsey had questioned their teenage son outside a convenience store for nearly 20 minutes without any clear basis. The third had come from a supervisor within the department who noted in a written report that Dempsey's behavior during a specific shift had seemed inconsistent with his normal conduct, a description that carried new weight in light of the drug test results.
All three complaints had been reviewed. None had resulted in suspension or serious disciplinary action. On paper, each one had been treated as an isolated concern. Viewed together after Riverside Park, they looked very different. One complaint involved an allegedly baseless stop and aggressive treatment of a Black man. Another involved prolonged questioning of a Black teenager without a clear basis. The third came from inside the department itself and described behavior that now appeared potentially consistent with an undisclosed substance problem. The pattern had been documented and minimized, and Dempsey had continued working until the evening he tackled a 17-year-old boy for reaching into his pocket in a public park.
The criminal referral was made to the District Attorney's Office two weeks after the incident. Prosecutors reviewed the body-camera footage, the drug test results, and the prior complaint history before deciding to pursue charges.
Dempsey was charged with assault involving a minor, false arrest, being on duty under the influence of a controlled substance, filing a false incident report in which he described Austin as having reached for a weapon, and misconduct in public office. The charges were announced publicly, and the body-camera footage was released to the media the same day.
The footage spread nationally within hours. The clip that circulated most widely was 44 seconds long and showed the moment Austin said he was calling his father, his hand moving toward his pocket, Dempsey's lunge, the tackle, and Austin hitting the grass.
Forty-four seconds captured almost everything anyone needed to understand what had happened in Riverside Park that evening. It was short enough to circulate everywhere and long enough to show the entire critical sequence without relying on anyone's summary. Austin announced that he was calling his father. His hand moved toward his pocket. The phone became visible. Dempsey lunged. Austin went down. Chloe screamed that it was a phone. Dempsey continued claiming a weapon. For the public, the power of the clip came from how little interpretation it required.
Chloe gave a brief interview in which she said she had told Dempsey at least four times that Austin was her boyfriend and that he had not listened to a single word she said. She said watching Austin be tackled and handcuffed for reaching for his phone was something she was still processing weeks later.
She said the apology the other officers had given them that night was appreciated, but it did not change what had happened.
Austin did not give an interview. His father spoke on his behalf and said his son had been on a date and had been assaulted by a police officer for it. He said the family intended to pursue every available legal remedy until there was accountability that matched the severity of what had been done to a 17-year-old boy on a Saturday evening in a public park.
The civil lawsuit was filed the following week, naming Dempsey personally, the department, and the city on theories that included institutional liability. The combined damages sought across both families' lawsuits totaled $1 million, and the filings included every piece of evidence the investigation had produced.
Russell Dempsey's criminal trial took place five months after the incident and lasted five days. The prosecution built its case on three pillars the defense spent the entire trial trying and failing to dismantle: the body-camera footage, the drug test results, and the prior complaint history.
