The Alameda County District Attorney's Office has decided to order the release of both foster parents of a missing 5-year-old boy, saying there is not enough evidence to charge them. According to the Chron, the foster father, Louis Ross, will be released later today. His fiancée, Jennifer Campbell, was freed yesterday. Oakland police had arrested the couple last Friday, apparently in the hopes that they would incriminate themselves. But according to the Trib, Campbell refused to talk to investigators. It's not clear whether Ross was cooperative. Police do not believe Ross' story that little Hasanni Campbell went missing from behind a Rockridge shoe store last month. Investigators also discovered that Ross had recently threatened to abandon the boy. In addition, Ross has admitted to failing a police lie-detector test.
