The Chicago Police Department won’t lose access to the controversial ShotSpotter gunshot detection system when the current contract expires at the end of Friday, the Chicago Sun-Times has learned.

Mayor Brandon Johnson’s office was hammering out a last-minute renewal to the nearly $49 million contract with ShotSpotter’s parent company, SoundThinking, according to a source familiar with the negotiations.

The frantic negotiations between the city and company came after Johnson’s office announced Tuesday that he was keeping his campaign promise to cut the cord on ShotSpotter but keep it in place until September — after the historically violent summer and the Democratic National Convention.

However, Johnson’s administration hadn’t yet struck a deal to keep ShotSpotter past Friday.
