FBI agents armed with search dogs have joined the effort to help find Hasanni Campbell, the five-year-old boy who went missing in Rockridge on Monday afternoon. According to the Oakland Tribune, "Louis Ross, the child's foster father, said he left the boy...outside his newer-model BMW in the back parking lot of Shuz, a shoe store in the 6000 block of College Avenue, about 4:15 p.m." on Monday. When the foster father returned from the store, the boy, who has cerebral palsy and uses leg braces, was gone. He either took off on foot (which is unlikely) or was taken from the parking lot.

Authorities have now searched his foster parents' home in Fremont. Police have also interviewed Hasanni's biological parents, "who live separately in San Francisco." Anyone with information about Hassani's whereabouts should call Oakland police youth services: 510-238-3641.
