Cloud over Chicago Police Superintendent Eddie Johnson's final days

CHICAGO (WLS) -- With CPD Supt. Eddie Johnson's plan to remain on the city payroll until year's end, it also means he will face ongoing investigations by internal affairs and the inspector general as he closes out his career.

Those tandem investigations are from last month's embarrassing - and not fully explained - incident, in which Johnson was found slumped over the wheel of his car after midnight. He was either asleep or passed out.

After the incident at a South Side intersection, Johnson blamed medication issues. It later came out that he had actually been drinking and dining with friends - facts made public by Mayor Lori Lightfoot after she had a conversation with the superintendent.

At Thursday's retirement announcement-turned-career tribute, the mayor asked that questions about the Johnson investigation be set aside - as the superintendent's family was present. She was asked anyway.

"Reality is the investigation is going to take a normal course," Mayor Lightfoot said. "The investigation, I'm sure because it's the inspector general, will be very thorough, but it's inappropriate for us to talk about anything related to the investigation, because he's going to be a witness, I'm going to be a witness."

Lightfoot said the investigation will continue even though Johnson is retiring. It isn't known what - if anything - could be done to Johnson though, if there were to be a finding of some wrongdoing after he left the city payroll.

Even as Johnson winds down, ABC7's I-Team was told Thursday that former Los Angeles Police Chief Charlie Beck will be brought in to work with him as an interim and co-superintendent. As the I-Team first reported on Wednesday, Beck will be in Chicago on Saturday and is expected to be named to the interim post.

"I do know Charlie Beck, he's been a friend and a mentor," Supt. Johnson told ABC7 political reporter Craig Wall on Thursday afternoon. "Back in 2016 when things were just spiraling out of control, I reached out to several other cities and he was one of them and he's been a friend to me from that moment."
