Berkeley, California - 6 people killed; 7 people injured in Balcony fall - June 16, 2014

Early Tuesday, 13 people, most of them young Irish students here on the visa program, were crowded onto a fourth-floor balcony off Unit 405 for what neighbors described as a loud party when the balcony collapsed, sending people tumbling onto the street below.

Six people were killed; five were Irish and the sixth had dual Irish-American citizenship, according to the Irish Embassy. Three of the dead were men, three were women, and all were in their 20s. At least seven others suffered injuries, some serious.

Some say the supporting structure had extensive water damage making the structure weak, and recommended all balconies checked for safety against water rot.
