VALLECITO, Colo. (CBS4) – Crews involved in the search for a missing Colorado boy returned to a lake near his father’s home on Wednesday after a dog hit on a scent near the shore.

Dylan Redwine, 14, disappeared on Nov. 19 when he went for a court-ordered visit with his father in Vallecito.

Crews have focused their search on Vallecito Reservoir in the months since Redwine went missing, and they returned there with a heavy presence this week.

The scent the dog picked up was found approximately 12 feet from the eastern shore of the reservoir.

There are several roads around there, and officials said they wanted to focus on somewhere Redwine may have been able to walk.

This week’s search effort had to be done quickly because even though the ice on the lake has melted, the waters are starting to rise.

Elaine Redwine, Dylan’s mother, told CBS4 by phone that she considers the effort a success despite the fact that nothing conclusive was found.

She said it allows searchers to rule out that part of the lake as a location for future searches.

“There’s a spring thaw now so it’s a little easier to get on the lake, near the lake,” the Colorado Springs resident said. “So we just really wanted some confirmation and to rule out the lake.”

“As I’ve said from the very beginning when we were searching for Dylan in the lake, it’s never an easy thing to do. But, we have to find him and if searching the lake will rule the lake out then that’s what we have to do,” Elaine said.

Leads in the search have been scarce, but Elaine believes her ex-husband Mark, Dylan’s dad, knows something. In February the two parents blamed each other during a two-part appearance on the Dr. Phil show.

Elaine says since that interview Mark has barely been heard from.

“He won’t speak with us,” she said. “He is very cryptic when he emails me and just, you know, no participation. … No involvement whatsoever.”

Elaine says she will be back out searching soon. Every day is what she calls a “Dylan Day.”

“He’s my son. I will never give up on him,” she said.

CBS4 tried to reach Dylan’s father for comment on Wednesday but he never answered his phone.
