May 28

On May 28, 1975, student Michael Slobodian carried out a fatal shooting at Brampton Centennial Secondary School in Ontario, Canada. Witnesses reported that Slobodian entered a classroom and unleashed gunfire, catching students and staff off guard. Two people were killed and 13 others were injured in the unexpected attack. After expending his ammunition, Slobodian turned the weapon on himself, dying at the scene. The shooting stunned the community and prompted calls for improved school safety and mental health support. It remains one of the earliest examples of school violence in Canadian history, raising awareness of the need for preventive measures.

On May 28, 2002, a symbolic closing ceremony marked the removal of the last steel beam from the World Trade Center site in Manhattan. This event signified the end of nearly eighteen months of painstaking debris removal and recovery operations following the September 11 attacks. Over 1.8 million tons of wreckage were cleared, revealing the scale of destruction and loss. Families of victims, first responders, and city officials attended the ceremony to honor the memory of those lost. The cleanup effort was one of the largest and most complex urban recovery operations in U.S. history. It paved the way for rebuilding, including the construction of the new One World Trade Center. The conclusion of the cleanup was a milestone in New York City's process of healing and renewal.
