OAKLAND (KRON) -- The guardians of a five year old boy still missing from Oakland's Rockridge neighborhood are pleading for the public's help in finding Hassani Campbell.

In an exclusive interview with KRON 4's Terisa Estacio, Louis Ross and Jennifer Campbell provided new details about the moments leading up to the child's disappearance from behind a shoe store on College Avenue Monday afternoon.

Ross and Campbell are the child's legal guardians.  Campbell's sister is Hassani's biological mother.

Ross says Hassani was standing in the alley at the back of the store when he went inside to get Campbell who is his fiancée.  Campbell was due to care for Hassani while Ross attended night school classes.  The little boy has braces on his legs to help with his cerebral palsy.

Ross and Campbell say they did not leave Hassani in the car.  When they returned to the alley, the child was missing.

Campbell says she's been in contact with Hassani's biological mother who says she doesn't know the boy's whereabouts.  Campbell is six months pregnant.  She and Ross say they're in the process of formally adopting Hassani.

The FBI confirms to KRON 4 News that it is now involved in the search for Hassani.  Oakland police searched the Rockridge area with dozens of officers and search dogs Monday evening.  Patrons at area bars and restaurants were kept inside the establishment during the search efforts.
