Glen Ellyn Police have issued a warrant for Alyah R. Collins, 23, who is accused of pushing a pool manager into the water during a July 5 “flash mob” takeover at Sunset Pool that forced law enforcement to evacuate the park district. 

According to incident reports released through a public records request, police are charging Collins with aggravated battery for pushing Christine Giunta-Mayer into the pool.   

The reports provide detailed accounts of the chaotic scene, in which an estimated 400 individuals forced their way into the pool without paying.

“Officers were told some people in the group were consuming alcohol, smoking cannabis, and some entered the pool without paying,” an incident report states. 

The scene further escalated when Giunta-Mayer was pushed into the pool, a moment that was captured in a widely circulated Instagram video and later confirmed via Twitch footage.  

According to an incident report, “A shorter black male with shoulder length dreads wearing no shirt walked up behind the subject wearing the pink shorts. The shorter subject had a yellow bracelet on his right wrist. Using his right hand, the shorter male forcefully pushed the subject in the pink shorts in the back. The push caused the subject wearing the pink shorts to bump into [redacted].” 

“The contact caused [redacted] to fall into the pool,” the report reads. “There was a very large crowd at the pool, and there was a huge reaction from the crowd when [redacted] was pushed into the pool. It was very clear the intent of the pushing suspect was ultimately to have  [redacted] fall into the pool.” 

The report says that Giunta-Mayer, who also coaches the Glenbard West Hilltoppers Boys’ Volleyball team, suffered hip pain from the fall but was not seriously injured and refused paramedic help on the scene. 

Investigators tracked down the key individuals involved in the incident through social media. 

A Glen Ellyn police officer noted they obtained footage from a public Instagram account @duffyclipzz, which showed the event unfold in real time. 

The police report says that two men, Dion Debrue and Collins, entered the pool without paying and later engaged in disruptive behavior. 

The report highlights the incriminating moment in a livestream video titled “Rooftop pool party join up right now!!!”

“At the 02:05:57 mark in the video, while [redacted] was speaking with several subjects, Collins pushed a subject into [redacted] which caused her to fall into the pool,” the incident report reads.

“At the 02:07:03 mark in the video, Collins admitted to an unidentified subject that he pushed [redacted] into the pool. The subjects then laughed.” 

The incident report also highlighted the community’s reaction on social media. 

"I observed a comment from user @duffelbagboyeli that stated 'bro dat lady has a family at home yall go get wats comin ta yall #ynthesedaysaintgotnorespect,'" the incident report reads.

As of press time, Collins has not been located. The police issued the warrant on July 9, with Collins ordered to be held without release. 

Police made one arrest during the incident. Jahad K. Henderson, 19, has been charged with illegal use of fireworks, obstructing an officer, making an improper U-turn and driving with expired registration.

The report details what led up to Henderson's arrest.  

“At approximately 1745 hrs, Officer C. Gibson #159 was attempting to direct traffic at the north exit of the Sunset Pool lot," an incident report reads. “While doing so, a silver Toyota RAV4 was proceeding in his direction. The vehicle was occupied by a Black male driver and a Black male rear passenger. As the vehicle pulled directly in front of Officer Gibson, the rear passenger was observed lighting a firework from inside the vehicle and throwing it out of the Toyota RAV4’s rear left window. The firework was thrown into a crowd of people, and the vehicle proceeded eastbound on Fairview. The firework was observed ignited/smoking, and then a few seconds later, it exploded.”

The report noted the firework exploded near pedestrians and officers.

“The firework that exploded was a ‘Consumer 1.4G’ Mortar style firework that sent large sparks towards Officer Gibson and numerous bystanders, which endangered the safety of multiple people,” the incident report reads. “That firework was within approximately 10-12 feet of numerous people, which caused numerous people to be alarmed/disturbed and react as if they were in rear of being hurt (taking cover, cover their faces, and turning their bodies). The entire incident, firework explosion, Toyota Rav4, driver of the vehicle, and rear passenger of the vehicle were captured on Officer Gibson's body worn camera, as well as other officers in car LPR cameras. As the vehicle fled the area, Officers provided the license plate information for the vehicle.” 

The passenger who allegedly threw the firework was later identified as Marlo Moore, 18, who was riding in the backseat of the Toyota Rav4 alongside Henderson. 

Police detained Moore and let him go but later issued a warrant after viewing footage allegedly showing him throw the lit mortar from the vehicle. 

“At the time of the traffic stop, Marlo was in the backseat of the Toyota and had illegal fireworks in his backpack,” the incident report reads. “Marlo was observed on BWC throwing the mortar shell firework from the Toyota, which was confirmed after he had been released from the traffic stop scene. Due to all the evidence, Marlo's compliance citation was dismissed and a warrant for Reckless Conduct and Possession, Sale, or Use of Fireworks will be issued for his arrest.”

The flash mob itself was initially organized on Facebook as a “31st Beach” event, a reference to a South Side Chicago beach party, but was redirected to Glen Ellyn’s pool.

Witnesses described a scene of widespread disorder.

"They were drinking and smoking weed and swearing a lot," a Glen Ellyn teen present at the pool at the time told DuPage Policy Journal. "Someone threw a lit cigar into the pool."

The chaos overwhelmed pool staff, prompting the Glen Ellyn Park District to close the facility early. Police from neighboring jurisdictions assisted in evacuating the crowd.

Glen Ellyn Park District Executive Director Dave Thommes later issued a statement about the incident. 

“The safety of our guests and staff is always our top priority,” Thommes previously said in an email to the DuPage Policy Journal. “We are working closely with the Glen Ellyn Police Department and other local agencies to evaluate all aspects of our response and operations—from admissions policies to staff training—to identify further measures that can help prevent and manage similar situations in the future.”  

In response to the incident, the park district now requires physical pool passes for all visitors to prevent unauthorized entry.
