On a late Sunday morning in February 2004, the Twin Peaks Station of the San Bernardino County Sheriff’s Department received a call about a male juvenile who had fled from a location intimately known to law enforcement. Soon afterward, a Twin Peaks Station deputy drove out to speak with the reporting party. Daniel Yuen arrived at CEDU, a sprawling but thinly populated private, for-profit residential treatment facility, on January 26, 2004.
