The father of missing 13-year-old Dylan Redwine said Tuesday he can't believe his ex-wife would suggest that he's behind their son's disappearance.
"I can't believe you can be married to someone for 20 years and they could say those kinds of things about you," Mark Redwine told KRDO Newschannel 13.
On Monday, Dylan's mother, Elaine, told ABC News that she was afraid her ex-husband may have done something to Dylan.
"I don't think Mark treats him very well," Elaine Redwine 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.'"
KRDO Newchannel 13 spoke to Mark at his home in Vallecito where Dylan was staying for a court ordered visit when he went missing on November 19.
Mark didn't want to go on camera, and said he has avoided the media thus far because he doesn't want to interfere with the search for his son or say anything negative about his ex, with whom he said he had a messy divorce.
He said his son, "means everything to me."
"I'm just trying to let the authorities do their job," he said. "My only concern right now is Dylan."
A poster with Dylan's picture is on Redwine's door, and a little boy's blue bicycle sits next to his home.
Investigators with the La Plata County Sheriff's Office could be seen driving past the house and told KRDO Newschannel 13 they were going door-to-door talking to neighbors.
Meanwhile, community members gathered for a prayer vigil Tuesday evening. Family friend Denise Hess planned the vigil after spending the last week organizing search parties.
"It's very much an emotional roller coaster for all of us," said Hess. "Because we come out, and we say, 'We're going to search this area and we're going to find him today.' Then darkness comes and we all go come a little bit defeated and with a little bit less hope."
Hess said Dylan is like a son to her, and she urges people to keep helping in the search any way they can.
"Please keep posting, keep watching, keep spreading the word and keep his name out there," she said. "Don't give up on him."
The Federal Bureau of Investigations is working with the sheriff's office in the search for Dylan.
On Sunday and Monday, investigators focused on the Vallecito Reservoir, near where Dylan's father lives. Dive crews used sonar equipped boats to comb the water, searching several areas cadaver dogs had reacted to. Nothing was found.
