Investigative Services Unit


The Investigative Services Unit for Mahoning County Board of DD is tasked with ensuring Health & Safety for the Individuals we serve.   We have three Investigative Agents (IA) who investigate allegations of abuse and neglect of individuals with disabilities. These are called Major Unusual Incident (MUI).

Our duties include investigating all health and safety issues (MUIs) involving clients established under OAC 5123:2-17-02 and meeting the guidelines of such investigations set forth by the Ohio Department of Developmental Disabilities.

Investigative Agents, Roseann, Amy and Tony bring a wealth of experience in providing services to the individuals of Mahoning County
