On June 16, 2015, shortly after midnight, five Irish J-1 visa students and one Irish-American died and seven others were injured after a balcony on which they were standing collapsed. The group was celebrating a 21st birthday party in Berkeley, California. The balcony was on the 5th floor of an eight year-old apartment building at 2020 Kittredge Street in Berkeley, then called Library Gardens. The district attorney of Alameda County launched a criminal probe into the incident. In January 2022, one of the injured died from a stroke related to the injuries.
