The parents of the first three victims of Elliot Rodger's murderous rampage say they're frustrated by authorities' handling of the case and angered by public health and legal systems that they believe failed their sons.

The bodies of James Hong, David Wang and George Chen were found inside a beachside apartment the night Rodger went on a killing spree near UC Santa Barbara, fatally shooting three students before taking his own life.

It's not clear how the slightly built Rodger was able to overpower them. Rodger shared the apartment with Hong and Wang.

The victims' parents told the Washington Post (http://wapo.st/1ptrsTS) they visited the crime scene and saw few signs of a struggle. They criticized investigators for not telling them how they believe the killings were carried out.
