A churchgoing girl was about to call her father when she was lured away by some students. Ten people hung around watching her being beaten and raped for up to two hours, with some using mobile phones to record the attack.
Her relatives have criticised the lack of security within the school and grounds. There were four security guards employed for the evening, but failed to ensure student safety by not spotting a gang of youths loitering.
The four accused, age 15, 16, 17, and 19, attended the Contra Costa County Superior Court in California donning bullet proof vests. A fifth person, Salvador Rodriguez, 21, is being held for his alleged involvement and is yet to be charged.
