Authorities are combing a Denver suburb for a 6-year-old boy who wandered away from his home on New Year's Eve and has now been missing for more than 60 hours. David Puckett—4 feet tall with light brown hair and blue-green eyes—left his Aurora home around 5:30pm Saturday wearing only a light jacket, per the AP. Police say David wandered away from school once before and foul play isn't suspected, but an Amber Alert was issued Monday to allow officers to share details of the case as impending cold weather is a concern. Search dogs, a helicopter, 100 officers, and 50 FBI agents have been searching within a 2.5-mile radius of the family home, reports the Denver Post. A $10,000 reward has been offered for David's safe return, reports KKTV. (More missing child stories.)
