New bodycam footage has revealed more crucial missteps made by officers after the horrific moment when a Chicago police officer was shot by her own partner in the line of duty.
Officer Krystal Rivera, 36, was shot by her partner Officer Carlos Baker while they were chasing a suspect through an apartment building in the Chatham neighborhood around 9.50pm on June 5, 2025.
New bodycam footage, obtained by the Chicago Sun-Times, showed officers delaying taking Rivera to the hospital as they tried to figure out who had the keys to the vehicle.
A large team of frantic officers yelled at others to get out of the doorway as three cops carried Rivera out of the building by her arms and legs, the footage showed.
'Get out of the doorway! Get out of the doorway!' one female cop could be heard yelling.
'Come on, come on,' a male officer yelled as they carried her down the sidewalk.
Others went deeper into the building, assuming the three would get Rivera to the hospital, but they would be quickly called back to the doorway as they needed the keys.
Nearly a minute after they carried Rivera outside, officers came back in search of the keys.
'Whose got keys? Whose got keys? I need keys to get out of here!' the officer, whose bodycam footage is being shown, yelled.
As the woman officer who ran back into the building to get the keys realizes they're the wrong ones, the cops are set into another frenzy to find the right ones.
'They're trying to move the officer out!' a man screamed.
The keys were then passed through an assembly line of officers before the man whose bodycam is being shown runs them to the street to hand them to a colleague.
This came after Baker took cover in the stairwell for more than 90 seconds after shooting Rivera, the Chicago Sun-Times reported.
Baker accidentally shot Rivera after he appeared to trip over his feet during the pursuit. The bullet hit Rivera, who was standing behind him, the outlet reported.
Baker told investigators that he carried Rivera down to the first floor before giving his keys to another officer and going back upstairs.
'I told them to take her to the hospital,' he told investigators, The Sun-Times reported.
Officers then went back to searching for the suspect and there was confusion over who shot Rivera.
Around 10.30pm, bosses had learned Baker was the one who shot Rivera. It is unclear how they learned this.
Baker had many complaints against him, which Rivera's family argued should have taken him off the force prior to the incident where their daughter died.
Rivera's family has sued the city over the incident. They accuse him of leaving her 'to die' due to their romantic relationship ending after she found out he was living with another woman, The Sun-Times reported.
Previously released bodycam footage showed he and Rivera getting out of a vehicle and running toward a man outside of an apartment building, demanding he 'freeze' and raise his hands. But the man instead ducked into the building and bounded up the stairs, with Baker and Rivera pursuing close behind.
As Baker made his way up the stairs, with Rivera on his tail, the suspect - who was later identified as Adrian Rucker - ducked into an apartment. Baker then kicked down the door as the suspect proceeded to flip over the couch.
At that point, another man - later identified as Jaylin Arnold - could be seen exiting a room with a long gun in hand. Baker appeared to quickly react, turning and firing one shot - and Rivera fell to the ground.
Meanwhile, Baker ran up the stairs, where he caught his breath before asking: 'Krystal, are you okay?' When he did not receive an answer, Baker could be heard calling for an ambulance and asserting: 'I can't get my partner!' He also asked another resident of the building to call 911.
But about two minutes later, Baker could be seen going to check on his partner before additional units arrived on the scene to transport her to a local hospital.
Colleagues brought Rivera, a mother-of-one, to University of Chicago Medical Center in a squad car that crashed and caught fire because of a malfunction, according to Police Superintendent Larry Snelling. She was then transported in another squad car, and was pronounced dead at the hospital.
An ensuing autopsy found that the fatal shot pierced Rivera's skin and traveled through both her lungs, wedging itself in her ribs, The Chicago Tribune reports.
The Daily Mail has contacted the Rivera family lawyer, Antonio Romanucci, and the police for comment.
