Request an Investigator or Expert


Expert witnesses are available to all criminal public defenders upon approved request by an IDSD Investigator/Expert Program Administrator; this is inclusive of direct felony appointed attorneys, MAACS attorneys, Neighborhood Defense Services - Detroit (NDSD) defenders, or retained attorneys with an indigency order for their client. Private investigators are available to all with the exception of NDSD as NDSD investigation is funded separately.
