September 28

In October 1542, Portuguese navigator Juan Rodríguez Cabrillo led the first European expedition along the California coast. He anchored in a sheltered bay which he named San Miguel, now recognized as San Diego Bay. The landing marked the first European contact with the California region, opening the way for future exploration and colonization. Cabrillo's voyage provided valuable information about the Pacific coast's geography and indigenous peoples. Although Cabrillo died later that year, his pioneering journey left an enduring legacy in California history.

On September 28, 2023, a violent incident unfolded in the Delfshaven district of Rotterdam when gunfire and arson erupted at a residential building. Two people died in the initial attack as flames consumed part of the structure. The assailant then proceeded to the Erasmus University Medical Center, where a third victim was fatally shot inside a classroom. Police quickly secured both scenes and launched a major investigation into the motive and potential links between the two locations. The community was left reeling as authorities sought to determine whether the attacks were targeted or random. Support services were offered to witnesses and victims' families in the aftermath. The events raised concerns over public safety in urban residential and educational settings.
