(MCT) — Rocked by the arrests of three officers charged with conspiring to steal from drug dealers, Schaumburg has hired a firm co-founded by a former Chicago police superintendent to perform an in-depth review of its Police Department, the village announced Tuesday.

The firm, co-founded by former Superintendent Terry Hillard, will examine departmental integrity, staffing, training, internal oversight and management, among other areas, according to a news release from the village. The firm, Hillard Heintze, and a panel of retired police chiefs and other law enforcement experts are expected to deliver their findings within 90 days, officials said.
