About 9 p.m. Wednesday,William Eckert was found in the water near his boat at Holiday Hill Marina in the Edgewater area when a family friend went to check on him. Emergency Medical Services workers came to the scene but were not able to revive Eckert, Maryland Natural Resources Police said.

An autopsy is being conducted Thursday to determine Eckert's cause of death. Natural Resources Police spokesman Sgt. Brian Albert said that Eckert had a history of medical conditions, so it is possible that he did not drown.
