DURANGO, Colo. - The La Plata County Sheriff’s Office has created a “Dylan Redwine Task Force” to manage the investigation and efforts to locate Dylan Redwine.
Redwine, 13, went missing on Nov. 19.
Members of the task force, along with uniformed Sheriff’s Deputies, will be contacting residents from Vallecito Dam north through the Vallecito area, officials said.
The Sheriff's Office said they will not be conducting a house-to-house search, but the canvass is expected to take a few days.
The task force is asking the citizen volunteers who have been canvassing the area to stay away so as not to interfere with the task force’s search.
Deputies said La Plata County Search and Rescue Team members are on standby and will be called in to assist if any new leads are identified.
The La Plata County Sheriff's Office said it is investigating possibilities ranging from Dylan running away to a kidnapping.
Sonar sweep of lake
A sonar sweep of Vallecito Lake found no new clues.
Seven New Mexico State Police scuba divers used three different boats with four different sonar systems to sweep the southern end of Vallecito Lake Monday. That's where cadaver dogs from the La Plata County Search and Rescue Team alerted on a scent both Saturday and Sunday.
But divers didn't find anything.
Dylan's Mother speaks out
As the emotionally wrenching search for 13-year-old Dylan Redwine in southwest Colorado entered a second week Monday, the boy's mother began pointing fingers at her ex-husband.
Dylan disappeared during a court-ordered Thanksgiving holiday visitation with his father at the man's Vallecito home, northeast of Durango, authorities said.
Dylan's parents, Mark and Elaine Redwine, divorced in 2007. Last summer, Dylan, his mother and older brother moved to Colorado Springs -- about 300 miles away.
On Monday, Elaine Redwine told ABC News she fears that her ex-husband may have done something to "remove Dylan from the situation."
"I was married to Mark for a lot of years, and I know the way he reacts to things," the mother told ABC News. "If Dylan maybe did or said something that wasn't what Mark wanted to hear, I'm just afraid of how Mark would have reacted."
The mother also told ABC News she believes her ex-husband was upset that she was the court-mandated primary custodian of their son.
"I don't think Mark treats him very well," the mother said. "I would not put it past Mark to have done something to remove Dylan from the situation. You know, like 'if I can't have him, nobody will.'"
In a phone interview with 7NEWS, Mark Redwine responded to his ex-wife's remarks by saying she is making this "more than it needs to be."
The father added that he "needs to not lash out" at his ex-wife.
During the ABC News interview, the distraught mother made clear she's not sure what's happened to her youngest son -- but she fears the worst.
"I think somebody knows where he is. I don't know if somebody's hiding him or if somebody's already done something horrible to him," Elaine Redwine said.
"The panic is just, you know, Where is he? Is he hurt? Was he able to have turkey at Thanksgiving? You know, just, all the things you want for your children. And the panic sets in because I can't do anything," the mother added.
Dylan had been with his dad in Vallecito for just one day before he went missing on Monday, Nov. 19. Mark Redwine told La Plata County sheriff's officials that his son was in his home when he left to run some errands in town at 7:30 a.m. When he returned four hours later, the boy was gone.
The father reported his son missing that afternoon.
Dylan’s mother and older brother returned to the Durango area when he went missing. They insist Dylan wouldn't run away without contacting them. And if he did leave his father's home, he would have come to them.
"I don't mean to be a pessimist, because it's my son's life we're talking about, But Dylan would have called by now," Elaine Redwine said.
Dylan's friends in Bayfield told The Durango Herald that Dylan was supposed to meet them Sunday night, but he changed that to Monday morning. They told the newspaper they think Dylan hitchhiked to meet them and then was abducted.
A Colorado Bureau of Investigation spokeswoman told the Durango Herald that historically, an estimated 12,000 to 14,000 children in Colorado go missing every year. That works out to about 1,000 or more every month.
