Chicago police said the suspect, Adrian Rucker, had six outstanding warrants at the time of his arrest.
CHICAGO (WLS) -- A suspect is now facing charges in connection with the unintentional shooting death of a Chicago police officer.
CPD said 25-year-old Adrian Rucker pointed a rifle at police on Thursday night, when Officer Krystal Rivera was killed.
As the suspect appeared in court Sunday, a faith community wrapped support around the family of the fallen officer.
Multiple charges against the Freeport, Illinois man came down early Sunday, including armed violence and having an invalid FOID card.
CPD said the shooting happened around 10 p.m. Thursday.
Rivera was part of a team of officers that tried to stop someone who was believed to be armed near 82nd and Drexel.
Investigators say that person ran into an apartment, and officers chased him. Police say Rucker then confronted the officers with a rifle inside the building before leaving the scene.
Prosecutors in court Sunday said as the officers pursued Rucker, Officer Rivera was accidentally shot when a fellow officer's weapons discharged.
Rivera's mother was in court Sunday for the appearance and did not comment publicly.
Prosecutors told the judge Rucker is a convicted felon who had several warrants for his arrest. The judge ordered Rucker to remain in custody, denying him pretrial release.

"All of Chicago felt the pain of her death, and we need to make sure the a message is sent every time this happens that when someone is responsible that we will not tolerate that," 15th Ward Ald. Ray Lopez said.
Prayers for the family of Officer Rivera were given Sunday at Faithworld Church.
"Wrap your loving arms around her family and especially her precious daughter be her covering and be her comfort," Pastor Daniel Cruz said.
There were also prayers for the fellow officer whose weapon unintentionally hit Rivera while they were in pursuit of a suspect.
"Father, we pray you would give her strength beyond comprehension, that you let her know that she is loved," Cruz said.
At Sunday's service, they remembered Rivera being faithful, involved and inspiring to young women.
"I was just shocked," Pastor Jennifer Cruz said. "I'm still shocked. It's like we just can't believe it she was just here and now she is gone."
Friend and fellow church member Rich Santiago lost his son during COVID. His son was a Cook County Sheriff's deputy. They all played volleyball together.
"She was so genuine to who she was as a person... I was devastated, because it brought back emotions for my son," Santiago said. "I'm going to miss her."
CPD Supt. Larry Snelling led a moment of silence for Rivera at a South Side event on Saturday.
He urged the public not to rush to judgment, as the investigation is ongoing.
Snelling says any information gained from a review of what occurred will help inform future training of officers.
Police said Rucker had six outstanding warrants at the time of his arrest.
Rucker is due back in court June 12.
As for the family of Officer Rivera, they will proceed with plans for Rivera's memorial services, possibly for the end of the week.
