The family of the East Bay boy who has been missing for one week is holding a vigil tonight in Oakland.
Hassani Campbell is just five years old. His foster father said he left the little boy in his car while he walked around to the front a shoe store where the boy's foster mother worked last Monday afternoon.
Louis Ross said when he got back to the car, Hassani was gone.
This afternoon friends, family and strangers will gather in Rockridge to remember Hassani and try to bring attention to the case.
The vigil is scheduled to start at 4 p.m. near the Shuz shoe store where his foster mother worked.
Also Monday, Oakland police announced a $10,000 reward was being offered to anyone with information leading his whereabouts.
As in all missing child cases, the family has been questioned several times by police. Ross told NBC Bay Area that he and the boy's foster mother, Hassani's aunt, are fully cooperating with investigators. He also told NBC Bay Area by phone that he had nothing to do with Hassani's disappearance and that he and the boy's foster mother have agreed to take lie detector tests.
Ross took the polygraph test last week but the foster mother, Jennifer Campbell, is pregnant and didn't want to take the test for fear it would harm her unborn child, the San Francisco Chronicle reported.
Police are not commenting about the polygraph test.
Police also towed Ross' car but have not said yet whether they have found anything important to the case. FBI agents have also searched the Fremont home where Hassani lives with his foster parents.
Hassani has cerebral palsy and wears braces on his feet to help him walk. The prosthetics, adorned with Spiderman logos, would not be visible because they are fitted just for his feet. While he can walk, Hasanni's disability prevents him from running or jumping.
The National Center for Missing and Exploited Children has also joined the search.
Hassani is African American with brown hair and brown eyes. He is about 3 feet tall and weighs 40 pounds. He was last seen wearing a gray sweatshirt and gray pants.
