KUSA - When a child, like 13-year-old Dylan Redwine goes missing, the clock starts ticking. Every hour that passes brings less of a chance that the child will be returned alive and well.
Redwine has been missing from the Vallecito Lake area in southwestern Colorado since Nov. 19, 2012.
"The first thing you do is basically conduct the investigation as if it's the worst possible situation and let the terms of the investigation determine which direction you go to," said Bob Hoever from the National Center for Missing and Exploited Children.
The center has created a task checklist for investigators to use so they don't miss any clues.

Frequently, local law enforcement agencies call the FBI for additional help in missing kid cases.
"If we know the child has vanished from a certain area, we'll start stopping cars," FBI Special Agent Dave Joly said. "We will start knocking on doors, checking businesses, looking at video, anything that can provide us a step in the right direction.
Experts say abductions by strangers are rarities. More often a relative, family friend or neighbor is the perpetrator in an abduction.
As for the Dylan Redwine case, investigators won't tell 9Wants to Know all they are doing to find out who's responsible. However, they did answer some additional questions this week.

They say they have searched activity on electronic devices including Dylan's missing phone, although they will not be specific about how many devices they searched.
They also say that they asked Dylan's mom Elaine to bring some of his personal items from her home in Monument so search dogs could pick up Dylan's scent.
9Wants to Know asked why investigators did not try to obtain a scent off the pillow Dylan supposedly used the night before his disappearance.
A sheriff's office spokesman said it was likely several people's scents would be on a pillow, and they get better results if they can guarantee a single person's scent.
Kidnapping case experts encourage community members to keep circulating fliers about Dylan Redwine's.
"It's like trying to find a needle in a haystack," Hoever said, "and the more eyes and ears you have the smaller the haystack becomes."
