Charges filed after a detainee was allegedly found with a gun at the Cook County Jail

COOK COUNTY, Ill. — Multiple investigations are underway Friday after a detainee who was arrested for allegedly punching a police officer was allegedly found with a gun at the Cook County Jail.

On Wednesday, 18-year-old Kemari Johnson revealed to his probation officer that he had been in possession of a gun for as long as a week.

Records show a probation officer met with Johnson to put an ankle monitor on him, but during the meeting he heard Johnson mumbling, after which the suspect asked, “Can I give you something back?”

Johnson then allegedly reached into his pocket and pulled out a magazine, documents state. He then allegedly reached into his pants, pulled out a gun and placed it on the table.

Johnson has since been charged with possessing a firearm in a prison, raising questions about where the gun came from and how long he kept it in prison.

Johnson was taken to the facility after his arrest on Nov. 11 during a domestic incident in which police say he pushed through a doorway in an attempt to attack his uncle before allegedly attacking an officer and throwing him to the ground.

Johnson was charged with aggravated battery in connection with this case.
