The La Plata County Sheriff's Office will be back on Middle Mountain next week to search for further evidence in the homicide of Dylan Redwine.

His partial remains were discovered there in June of 2013, seven months after he disappeared from Vallecito on a court-ordered visit with his father, Mark Redwine.

"We look at this like working to put together a jigsaw puzzle," said Lt. Dan Bender, a spokesman for the La Plata County Sheriff's Office. "Out of 1,000 pieces, we don't know the connection that one piece has. And the average jigsaw puzzle user has the advantage of a picture on the box."

The investigation has been ongoing since Dylan's disappearance in November of 2012.

"It can be an item, it can be information, it can be a number of things," Bender said of the many pieces of the police search. "We still have investigators assigned to it. Any loose ends we can tie up, the more pieces we can get, the more we can complete that puzzle, and the closer we'll be to obtain justice for Dylan."

The 13-year-old's disappearance was classified as a homicide in 2015. The sheriff's office named his father a "person of interest" in the investigation later last year.

Only the top part of the road will be closed. The sheriff requested the closure because the road is narrow and twisty, and there isn't much room for investigators to park and begin searching, Bender said.

The Middle Mountain area north of Vallecito Reservoir will be closed to all public entry from Wednesday, July 6 through Monday, July 11, the U.S. Forest Service said in a release on Friday.

The closure will include Middle Mountain Road (Forest Road #724), which will be closed to all entry about three-quarters of a mile before the Cave Basin Trailhead. This will block access to the Cave Basin Trailhead and Tuckerville. In addition, the Runlett Park Trail will be closed from Runlett Park to a point two miles south of Middle Mountain Road. The trails and Middle Mountain Road below the closure area will remain open, and dispersed camping is allowed in the area below the closure area.

Bender said there will still be plenty of four-wheeling and camping spots available, they will just be below the search area.

Forest Service patrols will notify campers and others using the closure area over the July 4th weekend that they must relocate no later than early Wednesday morning. The Sheriff's Office and Forest Service law enforcement officers will also conduct a sweep of the National Forest above the closure to notify campers they must relocate by Wednesday.

"Every summer, we have found some clues," Bender said.
