AURORA, Colo. – The search for a missing child can tax many law enforcement resources, as it appropriately should. There are few events that can elevate the heart rate of so many like missing children.

Police in Aurora, Colorado are searching for a 6-year-old boy who is believed to have wandered away from his home on New Year’s Eve.

The FBI and other law enforcement agencies were helping search for David Puckett on Monday by going door-to-door within 2.5 miles of his home. Bloodhounds are also searching for him, reported CBS News.

Police say foul play isn’t suspected, but they’ve asked for help to find David as quickly as possible. Aside from the obvious reasons, cold weather looms.

His mother said he was only wearing a light jacket Sunday night when she made a tearful appeal for people to help find him.

To this point, police have used a bloodhound and a helicopter, but have not been found any clues.

The young boy has a slight learning disability, and has wandered off from school once before. As of now, police are operating under the probability that he ventured away from safety again, according to CBS Denver.

On Monday afternoon, the Colorado Bureau of Investigation issued an Amber Alert in the case, something that was delayed initially because there was no immediate evidence of an abduction.

“We’re obviously very concerned. We’re all cold standing here bundled up, so the weather and the amount of time is increasingly concerning to us and that is why the CBI has issued this Amber Alert for us today,” Aurora police spokeswoman Crystal McCoy said.

Puckett was last seen around 5:30 p.m. on Dec. 31 in the 15700 block of East Amherst Place in Aurora, a suburb of Denver.

He is 4 feet tall, weighing 48 pounds and has light brown hair with brown eyes. He was last seen wearing camouflage pants, a black shirt with a tan coat and black and orange boots.
