Our company employs active or retired law enforcement forensic laboratory staff that are highly respected leaders in their particular disciplines with a vast array of experience in a wide variety of cases. Criminal cases cannot be undertaken within Michigan, but we are available in other states for criminal cases. We are required to avoid cases that would pose a conflict of interest to the employees still actively employed in state government (affecting criminal cases in Michigan and Minnesota only).
