A Severna Park man died from an apparent heart attack while boating on an Anne Arundel County creek, Maryland Natural Resources Police said Saturday.

Frederick Ervin Jr., 56, and a friend were taking a boat out for the first time this year on Crownsville's Plum Creek at about 5:30 p.m. on Friday when Ervin felt sick, said Sgt. Brian Albert, a police spokesman. Plum Creek is a tributary of the Severn River.

Ervin went to the side of the 33-foot center console power boat and leaned over, falling into the water, Albert said.

Ervin's body was taken to the Office of the Chief Medical Examiner for an autopsy; police believe he may have suffered a fatal heart attack, Albert said.
