There is still no sign of 5-year old Hasanni Campbell. His foster dad reported him missing on August 10th.
A search warrant issued on August 11th shows that police were looking for a "sword or cutting instrument" and biological evidence from the 5-year-old boy in his foster parents' home. Authorities confirm that Louis Ross, the boy's foster father, failed a polygraph test given by the FBI. [SOURCE]
The search warrant, issued at 5:45 a.m. Aug. 11 in Alameda County, was for the home on Roxie Terrace in Fremont, where the boy lives with his foster parents, Ross, 38, and Jennifer Campbell, 30.
The warrant was also for Ross' 2002 BMW.
Police recovered a pair of latex gloves, eight DNA swabs and four fingerprint lifts from the car but took nothing from the home. It was unclear why investigators were looking for a sword or cutting instrument.
