Hasanni was reported missing by his foster father, Louis Ross, who said the boy disappeared Aug. 10, 2009 from a car parked outside a shoe store in Oakland's Rockridge neighborhood.
San Leandro business owner Sherri-Lyn Miller founded Citizens for the Lost Society in the wake of Hasanni's disappearance, and the group has helped organize searches, vigils and fundraisers since he went missing.
The nonprofit is holding a grand opening Sunday for its new office in San Leandro at the site of Miller's print shop that has been transformed into the organization's headquarters.
Alameda County Supervisor Gail Steele is scheduled to take part in a ribbon-cutting ceremony at the event, scheduled for 2 p.m. at 15976 E. 14th St.
On Tuesday, members of the group will meet with Alameda County Chief Deputy District Attorney Tom Rogers to discuss any possible new developments in the case.
On Aug. 28, 2009, Oakland police arrested Ross and 30-year-old Jennifer Campbell, Hasanni's aunt and foster mother, on suspicion of murder. The district attorney's office declined to file charges though because of insufficient evidence, and the couple was released.
In early January, the foster parents moved out of the Fremont home where Hasanni had lived with them. Miller said she heard Ross is now living in Maryland, and Campbell is in Arizona.
Miller said she still believes one or both of Hasanni's foster parents have information they are not telling authorities about his disappearance.
"Louis Ross and Jennifer Campbell need to start telling the truth," she said.
Following the meeting with Rogers, the group plans to hold a rally at 4 p.m. outside the district attorney's office at 661 Washington St. in Oakland. A prayer vigil is also planned for Tuesday evening at Westminster Hill Presbyterian Church at 27287 Patrick Ave. in Hayward, Miller said.
On Aug. 14, the group also plans to hold an electronic waste collection event and fundraiser for Citizens for the Lost Society.
Hasanni's grandmother and aunt, Pamela Clark and Trinity Schwabacher, are scheduled to participate in at least one of the week's events, according to Miller.
"It's been a long year," Miller said. "We did a lot in a year, but we want people to know it doesn't just stop with Hasanni. There are other children and people out there that are missing and lost, and we want to focus on all the people that are forgotten."
