BOISE, Idaho, Aug. 1 (UPI) -- Investigators have new leads into the disappearance of an 8-year-old boy more than a week ago, police in Boise, Idaho, said Saturday.
Jim Kerns, the deputy police chief, said investigators narrowed their areas of interest in the search for Robert Manwill. He said "one of many areas of interest" is a residence in southwest Boise, but he wouldn't say why.
"We believe that Robert may be the victim of a tragic event. Our leads are narrowing and are becoming more specific," Kerns said.
Ground-penetrating radar borrowed from Boise State University is being used in the investigation, the Idaho Press reported.
"I can say many areas have been investigated, more areas may be searched, and some locations may be investigated time and time again as new or different information emerges," Kern said. "Until we find Robert, we will continue to look and follow up all credible leads. Finding Robert remains our priority."
