Homicide detectives have taken over the lead role in the investigation of missing 22-month-old Dwight Stallings.
However, Sacramento County sheriff's officials stressed that giving homicide detectives command of the search for the youngster does not mean that it is a death investigation.
"Due to the unusual circumstances present in this case, the decision was made that homicide detectives would be better equipped to handle the investigation from this point forward," said a Sheriff's Department news release.
Detectives scheduled a meeting in the south area with volunteers, who will help distribute and post fliers with Dwight's picture and information about the case.
Detectives have obtained a previously unreleased photo of the child. It was provided to media outlets Friday in the hope that somebody will recognize the boy and provide information on his whereabouts.
Authorities say the child has not been seen by family members since April 2011, and his mother, Tanisha Edwards, 35, has been unable or unwilling to reveal what happened to him.
Edwards' arrest last week in Elk Grove came after Sacramento County Child Protective Services spent months looking for the mother and child, seeking help at times from law enforcement in the "Baby Dwight" case.
