On July 30, 1920, the steamboat Rival docked at Bird's Run Landing in Pittsburgh after making stops along the Monongahela River. It was the engineer who entered the ballast bunker and discovered a lifeless body of a stowaway partially buried beneath a pile of coal. Neither the engineer, captain, nor any of the crew members had any idea how, when, or why he had gotten aboard the vessel, and no identification was found of the body. But things got even stranger after the body of the unidentified man was taken to the city morgue. (Note: No new episodes in August. Pennsylvania Oddities will return on September 1.)
