Maryland State Police
The Maryland State Police's Investigative Division have been involved in several cases related to the GoatMan legend. These include fatal attacks and missing persons. In most of these cases, the state police were called in to provide assistance (especially forensic analysis) to local authorities.
Federal Bureau of Investigation
The FBI's involvement in the GoatMan story centers around Special Agent Glenn Dale, who disappeared while investigating a group of missing persons cases. Agent Dale's activities (and subsequent disappearance) have been the subject of speculation; this was fueled in 2009 when an unmarked box was found to contain the daily audio logs of his investigation. Prior to this, FBI teams have been involved in searches and recovery of remains for several cases rumored to be victims of the GoatMan.
