Chief of Detectives Brendan Deenihan leaving CPD: sources

Deenihan was promoted to Deputy Chief in the Detective Division in January 2020 after being with the department for 22 years.

In his career, he has also served as Commander of Area Central Detectives, Commander of Internal Affairs and as a Homicide Lieutenant in Area South. 

Deenihan is expected to sign off just days before the highly contested race for Chicago mayor.

The majority of mayoral candidates say they'd fire Chicago Police Supt. David Brown if elected.

Even if he does keep his job, he'd be forced to resign in October when he turns 63 — that is the mandatory retirement age for Chicago cops and firefighters.

The Chicago Police Department has not returned FOX 32's request for comment about Deenihan leaving the department.
