UCD student Eimear (21) was at the party with her friend and housemate Olivia Burke when the tragedy occurred.

The pair worked together at sushi restaurant Hana Zen in San Francisco, while on their working summer holiday.

Restaurant owner Alvin Louie said that Eimear, from Foxrock, worked her first day at the business on Monday.

She said that the two Irish girls were "great young kids, very enthusiastic".
