World Trade Center

[Brian McKenna]

Name the two former minor leaguers to die at the World Trade Center on 9/11.

[Honus Wagner]

I could only find 1 player...
Mike Weinberg (Died on September 11): A former minor league outfielder in the Detroit Tigers' system and a New York fireman, the 34-year-old Weinberg was off duty on the day of the terrorist attacks on the World Trade Center, but decided to report to the scene. He perished when the buildings of the Twin Towers collapsed. Weinberg was the only former professional baseball player-either active or retired-who was killed in the attacks.

and the article says, he was the only one?

Unless it's Ace Bailey of the Bruins or maybe a non-American?
