“There is no evidence to corroborate the Supervisor’s claim,” the report said. “The Supervisor did not obtain authorization from CPD to conduct a study, did not inform a single person of the Supervisor’s ‘study’ prior to the OIG’s investigation, did not create a methodology, did not create any documentation related to the study, did not observe the child’s interactions with CPD officers at the district, conducted no interviews with the ‘participants’ of the study, had no timeline for the completion of the supposed study, and apparently created no metrics to measure the effectiveness of the study.”
