More than 150 volunteers search for 6-year-old in Aurora missing since Saturday

AURORA, Colo. -- Police said Sunday that finding a 6-year-old boy who was reported missing Saturday night is their "highest priority investigation right now."

More than 150 volunteers helped the Aurora Police Department search for David  Puckett at Olympic Park (15501 E. Yale Ave.).

Police said they were also using drones to search for the boy. At a news conference Sunday morning, investigators said it appears the boy left on his own.

The Arapahoe County Search and Rescue, the National Center for Missing and Exploited Children, the Denver Police Department and the FBI are involved in the search.

"We are using search team organizations in addition to local law enforcement partners and APD officers to continue our search including helicopters and bloodhounds," police said on Facebook.

Investigators sent out three emergency notification calls to approximately 27,000 residents in the area to let them know the boy is missing.

"We are asking everyone to check your property. Children will often hide in small spaces and not come out even if called upon," police said on Facebook.

The boy's mother, Stephanie Puckett, was emotional at a news conference Sunday morning.

"Help me find David. ... He's only 6 years old," Puckett said. "He's a good boy."

David was last seen wearing camouflage pants, a black shirt, a thin tan coat, and black and orange boots, police said.

David was last seen at 5:30 p.m. Saturday in the 15700 block of East Amherst Place.

Anyone who sees David is asked to call 911.
