A man from Chicago with a felony background, facing charges linked to an attack at a train station on August 10 that resulted in the death of a 9-year-old boy, was released from jail on Monday as he awaits trial.

Michael Korosa, 52, has been charged with felony involuntary manslaughter after Elijah Flores died during an attempted robbery gone wrong. 

Flores was under the care of Jonah Soria, 22, at the time of his death. Soria was dating Flores’ mother.

Subsequently, Soria reportedly picked up Flores and boarded another train, where the boy became unresponsive. A concerned bystander dialed 911, leading to Flores being urgently transported to the hospital, where he unfortunately passed away.

Korosa was apprehended on August 30 and also charged with one count of felony aggravated battery involving a transit employee in connection to the incident. Nevertheless, he was released from custody on Monday as his trial is pending.

The Chicago Sun-Times reports that Korosa has a prior felony conviction, having served a two-year prison sentence for using a box cutter on a Walgreens security guard in 2020.

Separate from the incident involving Flores, Korosa was detained three days post the alleged train attack for possession of a controlled substance and drug paraphernalia, according to jail records.

Soria has not been charged regarding Flores’ death but was arrested on an outstanding warrant due to failure to appear in court related to a retail theft and battery case in a different county.

It is unclear if Korosa has an attorney representing him. Fox News Digital reached out to the public defender’s office and the Chicago Police Department.

On Monday, President Donald Trump warned that he would intervene to lower crime in Chicago. 

“At least 54 people were shot in Chicago over the weekend, 8 people were killed. The last two weekends were similar. Chicago is the worst and most dangerous city in the World, by far,” he said on Truth Social. “Pritzker needs help badly, he just doesn’t know it yet. I will solve the crime problem fast, just like I did in DC. Chicago will be safe again, and soon. MAKE AMERICA GREAT AGAIN!”
