Pastor Daniel Cruz remembers the last time Chicago Police Officer Krystal Rivera attended service at his Faithworld Church. She can be seen in a short church recording of a worship service.

“She was sharing how she wants her daughter to also just really get to know the faith,” Cruz said.

The Northwest Side church had been her church home for nearly 20 years.

“We were completely shocked. I don’t think I’ve wept as much in recent months as I did after I heard the news… that she had passed away,” Cruz said.

Officer Rivera died Thursday night after police officials said she was unintentionally shot and killed by another officer as they encountered an armed person during a foot pursuit in the 8200 block of South Drexel Avenue in the city’s Chatham neighborhood.

Saturday afternoon, while at an unrelated event, Chicago Police Superintendent Larry Snelling held a moment of silence for the slain officer while asking for prayers for the other officer involved.

“That officer is in a very, very tough place, unimaginable what that officer has to be feeling right now,” Snelling said.

Several people, including the person who allegedly aimed a rifle at officers, remain in police custody.

Rivera, a four-year veteran of the force, was assigned to a 6th District tactical team. She was also single parent to a young daughter whose birthday party is this weekend.

Those who knew Officer Rivera said she had sweet spirit and a servant’s heart.

“When we were talking to Krystal two weeks ago, she was telling us that one of her greatest joys was doing what she’s doing right now, that was her greatest joy,” Cruz said.

According to the Chicago Police Memorial Foundation, seven other Chicago police officers have been killed in the line of duty since 2018.

While many in the city mourn the loss of another Chicago police officer, Pastor Cruz wants Officer Rivera to not only be remembered as one of Chicago’s finest, but also as a loving mother, daughter and sister who dedicated her life to others.

“I try not to focus on how she died, but how she lived, and she just was a precious soul,” Cruz said.
