A plaque has been erected in memory of the five young adults who lost their lives in a tragic balcony collapse.

The plaque was unveiled at a memorial event yesterday organized by the Consulate General of Ireland to the Western United States and the Irish immigration pastoral Center, alongside the city of Berkeley.

The tribute honors the five Irish college students, Olivia Burke, Eoghan Culligan, Lorcan Miller, Niccolai Schuster and Eimear Walsh, and their Irish-American friend Ashley Donohoe all died on June 16th 2015.

The students were killed when a balcony they were on collapsed. The group were celebrating a 21st birthday party while on their J-1 summer exchange in California.

The district attorney of Alameda County launched a criminal probe into the incident.

Last year, a settlement was reached in connection with the incident with "design defects and construction flaws" paramount to the balcony collapse.

Mayor of Berkeley Jesse Arreguin stated at the time, “The balcony collapse was one of Berkeley’s darkest days, but in the aftermath, it has brought us closer together.

“I want to thank the first responders for their heroic response during that fateful night, and to everyone who has been involved in advocating for the creation of improved building codes to prevent such tragedies from happening again," she said.
