La Plata County Sheriff's Office

Members of the New Mexico State Police Search & Recovery Team scour Colorado's Vallecito Lake on Monday for any clues in the disappearance of Dylan Redwine.

The search for a 13-year-old Colorado boy who went missing last Monday during a court-ordered visit with his father has been suspended, according to authorities.

The La Plata County Sheriff's Office announced it was suspending its search for Dylan Redwine after a two-day sweep of a lake near his father's house yielded no clues, officials said. The investigation into the teen's disappearance will continue.

Dylan was reported missing on Nov. 19 by his father, Mark Redwine, who said he left the house in Vallecito, La Plata County, about 7:30 a.m. and returned several hours later to find his son gone.

"After 8 days of searching in Vallecito, all areas have been covered by ground, by air, by water," La Plata County Sheriff’s Office spokesman Dan Bender told NBC News on Tuesday by email.

The boy had been visiting from Colorado Springs, where he moved with his mother and brother over the summer, NBC station KUSA of Denver reported. 

La Plata County Search and Rescue K-9s flagged an area on the southern end of Vallecito Lake on Saturday and again on Sunday, prompting scuba divers from the New Mexico State Police to search the area. But the lake search ended "after extensive sonar sweeps found nothing," according to a press release from the sheriff's office.

No further dives of the lake bottom or field searches are planned unless there are new leads, police said.

Dylan is 5 feet tall and 105 pounds, with blonde hair and blue eyes, according to authorities. He may be carrying a black backpack.

"Every time someone sees a young male child with light hair or with a black backpack, we're getting calls," Bender said Monday, adding that the lake search was "devastating" for the family.

The Redwine family told NBC affiliate KUSA they are still holding out hope Dylan is alive.

"It's been killing me. It's been hard for our whole entire family," Cory Redwine, Dylan's 21-year-old brother, said Monday. "He was my hero just as much as I was his."

While the Redwine family doesn't believe Dylan ran away, La Plata Sheriff Duke Schirard told KUSA, "The fact that he may have run away is our hope. Because at the other end of the continuum would be foul play or he could have been abducted by someone."

Updated at 11:11 a.m. ET -- A dive team from the New Mexico State Police was resuming its search near the dam at Vallecito Reservoir on Monday for Dylan Redwine, a 13-year-old boy who disappeared from his father's home during a court-ordered visitation over Thanksgiving in southwestern Colorado.

According to The Durango Herald, the divers began the search Sunday in an area that cadaver dogs had flagged Saturday while aboard watercraft.

No remains had been found by Monday morning.

Cadaver dogs and patrols were also going out around the 12 miles of shoreline, La Plata County Sheriff’s Office spokesman Dan Bender told NBC News on Monday.

"It's been devastating for the family," Bender said.

Dylan was reported missing on Nov. 19 by his father, Mark, who said he left the house in Vallecito, La Plata County, about 7:30 a.m. and returned a few hours later to find his son gone.

Dylan was described as 5 feet tall, 105 pounds, blond hair, blue eyes with a fair complexion. He was last seen wearing a blue and white Duke Blue Devils baseball cap, a black Nike T-shirt, black basketball shorts, black Jordan tennis shoes and a black backpack.

On Saturday, about 200 volunteers and law enforcement officials went door to door in the region and searched hills near Vallecito Lake, the Denver Post said.

"Every time someone sees a young male child with light hair or with a black backpack we're getting calls," Bender said, adding that there had been no confirmed sightings of Dylan.

The Herald said police are also looking to speak with two boys who were seen by a postal worker on Nov. 19 at the Vallecito Lake Country Market, according to Bender.

The postal worker, who knows Dylan, said one of the boys looked like him, adding that both teens were also wearing black backpacks. As of Monday morning, Bender said police had not heard from the two boys.

According to a news release, the La Plata County Sheriff’s Office is “working with local representatives of the FBI to share information and resources as they continue to develop leads on where Dylan may be," The Herald reported.

“Scenarios from abduction to runaway are being examined,” the release said. “Without any new clues, we have to continue to consider any and all possibilities." The FBI has not officially taken over the investigation, Bender told NBC News.

Dylan, his mother and his brother had moved to Colorado Springs this summer, NBC station KUSA of Denver reported.

Vallecito is more than 7,000 feet above sea level in the middle of rugged terrain. The weather in the area in the past few days has been clear and cool, with highs in the 50s and lows below freezing. 

Anyone with information on Dylan's whereabouts is asked to contact La Plata County Sheriff's Office investigators at 970-382-7015 or 970-382-7045.
