Black Saturday was a 1903 disaster which left 12 spectators dead and injured 232 when a section of balcony collapsed during a baseball game between the Boston Braves and Philadelphia Phillies.
[1] National League Park (also known as Baker Bowl), was built in 1895 using novel construction techniques, prominently featuring a cantilever design to support the roof and upper decks.
One of the men allegedly grabbed by the hair a thirteen-year-old girl named Maggie Barry from the group of children, and after a brief struggle, fell on top of her.
Accounts of the incident say that cries for help from the girl and her friends drew attention from spectators in the stadium above, and approximately 300 people crowded the balcony above the street to get a view of the commotion.
Under the weight of the curious onlookers, the overloaded balcony's supports apparently became detached from their connections at the wall, and plunged approximately 30 feet (9 m) to the street below.
