Boise police say they will resume their grid search for missing 8-year-old Robert Manwill Wednesday.
The family, through Robert's aunt, Trish Burrill, called for continued community support in the search.
"Anyone who has Robert in their heart is invited to wear a green ribbon upside down until Robert is found," she said.
Boise police worked Tuesday to recreate a detailed timeline of what Robert Manwill did on Friday — the day the 8-year-old disappeared and sparked a more than three-day intensive search in his neighborhood around south Vista Boulevard in Southwest Boise.

Police now say the boy was last seen wearing a faded blue T-shirt with a Superman logo, blue jeans and dark tennis shoes. He went missing from his mother's apartment complex near the intersection of Vista and Targee Street — about half a mile from Interstate 84 and even closer to the New York Canal.
Police, FBI agents and more than 100 volunteers have scoured the neighborhood, looking for nooks and crannies where the boy may have hidden — including tiny places where a small boy could tuck himself.
"Act like you're looking for a lost baseball," Officer Will Reimers told a group of volunteer searchers Monday.
"The family has said that he likes to sneak around and crawl in little places. He's an inquisitive little kid," said police spokeswoman Lynn Hightower.
Robert lives with his father in New Plymouth, but was visiting his mother and her family Friday, police said.
Police stopped traffic and searched nearby homes over the weekend. They have interviewed more than 100 registered sex offenders living nearby and chased 100 leads — none of which have panned out.
From an Idaho National Guard helicopter, police scanned the New York Canal and nearby railroad tracks and pools. A pond near the apartment complex was drained and searched.
Police have set up a dedicated tip line and e-mail address: 208-570-6457 and firstname.lastname@example.org.
The family has thanked the more than 100 volunteers for their aid. But police said Tuesday they no longer need people to offer up their help in the search — although they still want anyone living in the area to take an extra close look at any place in and around their property the boy may be hidden.
