A press release from the sheriff's office said the case is now in the hands of the Delaware County Prosecutor and pledged his cooperation and assistance of the officer in moving this matter forward.

Parks, 37, is preliminary charged with two counts of aiding, inducing or causing the dealing of heroin and marijuana, attempted dealing in marijuana and neglect of a dependent, according to court documents.
The arrest was part of a months-long investigation between the Muncie Police Department Narcotics Unit and the Indiana State Police.
