Zahra was reported missing about 2 p.m. Saturday. Police have said her father and stepmother reported she was last seen sleeping in her bed about 12 hours earlier, at 2:30 a.m.
But Hickory Police Chief Tom Adkins said Tuesday authorities have been unable to find anyone outside Zahra's immediate family who has reported seeing her in the past month, and investigators are not sure how long she has actually been missing. He told reporters an Amber Alert issued after the girl was reported missing was being canceled, and the investigation has shifted from a possible abduction into a homicide probe.
Investigators were searching where Adam Baker worked north of Hickory, said Nancy Webb, who lives next door to the site, on Tuesday.
