Rally organizer Sherri-Lyn Miller said at least 50 people are expected to gather tonight to boost public awareness about Hasanni, who went missing Aug. 10 from a car parked outside the Shuz of Rockridge shoe store in the 6000 block of College Avenue.
The boy was reported missing by his foster father, 38-year-old Louis Ross. Oakland police have said they are investigating Hasanni's disappearance as a homicide.
In August, police arrested Ross and 30-year-old Jennifer Campbell, Hasanni's aunt and foster mother, but the district attorney's office declined to file charges because of insufficient evidence and the couple was released.
Miller, a San Leandro business owner, has been organizing searches, vigils and fundraisers for Hasanni since his disappearance.
After they were arrested, Ross and Campbell stopped attending events and are no longer speaking with the media, according to Miller, who has interacted with other family members since then.
In early January, the foster parents moved out of the Fremont home where Hasanni had lived with them.
Miller recently established the group Citizens for the Lost to search for missing children, and said about 30 people came by the group's San Leandro headquarters this weekend to make signs and T-shirts for tonight's rally.
Oakland police Officer Jeff Thomason said the Police Department is still working the case.
"We have never stopped investigating it. With the level of evidence, witness statements, and canvasses, there's a massive level of information that's coming in on this investigation," Thomason said. "We're still pursuing this case, and we're not going to stop pursuing it until there's closure."
Anyone with information about Hasanni's disappearance is urged to call Oakland police at (510) 777-3211 or (510) 238-7934, or Crime Stoppers at (510) 777-8572.
Anyone who wants more information on the rally or wants to volunteer with Citizens for the Lost is encouraged to call (510) 276-9090 or send an e-mail to findhasanni@gmail.com.
The rally is scheduled for 6 p.m. outside police headquarters at 455 Seventh St. in Oakland.
