Mourners, including police officials from across the state, started to arrive before noon at Living Word Christian Center in Forest Park for the funeral of Chicago police Officer Krystal Rivera, the first such ceremony in 2025 for a CPD officer killed in the line of duty.
By 11:30 a.m., hundreds of Chicago patrol officers lined the driveway of the Forest Park shopping center where the center is located. They walked single-file around a large parking lot as piano music merged from inside the church. An American flag fluttered from a crane parked at the mouth of the driveway.
Illinois Gov. JB Pritzker and Chicago Mayor Brandon Johnson were in attendance along with department leaders.
Rivera, 36, a CPD officer for four years, was assigned to a tactical team in the Gresham District (6th) when she was mistakenly killed by her partner which chasing a suspect. She is survived by her adolescent daughter.
On June 5, Rivera and her team attempted to detain a weapons suspect in the 8200 block of South Drexel. That person ran into a nearby apartment, and Rivera and her team gave chase, police previously said. The officers were met inside by two other people, one of whom allegedly pointed a gun at Rivera.
Rivera’s partner, apparently standing behind her, fired a single shot, striking her in the back. With no time to wait for an ambulance, other officers placed Rivera in a CPD squad car to take her to University of Chicago Medical Center. During the drive, though, the police vehicle somehow caught fire and Rivera was transferred to another squad car. She was pronounced dead soon after arriving at the hospital.
The Cook County medical examiner’s office said she was shot once in the back. Her death was ruled a homicide, though her autopsy report hasn’t been finalized. A CPD incident report stated Rivera was shot in her left flank, presumably near an opening in her bulletproof vest.
In the chaos following the gunfire, the three people in the apartment were able to, briefly, evade police. Two were soon taken into custody, and one man, Adrian Rucker, was charged two days later. Rucker, 25, had six warrants at the time of his arrest, according to prosecutors. He was charged with armed violence, use of a firearm without a firearm owner’s identification card, possession of a fake ID and drug possession. He was ordered held pending trial.
Last weekend, authorities announced charges against the man who, police say, was the subject of the initial street stop that sparked the shooting. Jaylin Arnold, 27, was charged with armed violence, being a felon in possession of a firearm and possession of a controlled substance. Like Rucker, he was ordered held pending trial.
Less than a year ago, another officer in the Gresham District, Enrique Martinez, was fatally shot while on-duty less than a half-mile from where Rivera was shot.
