The La Plata County Sheriff's office on Thursday released new details about Dylan Redwine's whereabouts the day before he disappeared.
Dylan, 13, was reported missing on Nov. 19, less than a day after he arrived in La Plata County for a visit with his father.
Mark Redwine said he last saw his son early that morning at his home in Vallecito.
Officials revealed Thursday that Dylan arrived at Durango-La Plata airport at 5:46 p.m. Nov. 18; at 7:05 p.m., he was seen at a Durango Walmart; at 7:22 p.m., he went to a Durango McDonald's; and his last text message was sent at 9:37 p.m. on Nov. 18. They hope the information will yield new information.
A task force of local and federal law enforcement agencies continues fielding tips about the boy's whereabouts. Most recently, investigators, sometimes in snowshoes, have searched under bridges and other sites in La Plata County and two other places.
Other agencies have helped the search in other states, the sheriff's department wrote in a news release. Anyone with information on Dylan's whereabouts was urged to contact investigators Dan Patterson at 970-382-7015 or Tom Cowing at 970-382-7045.
Messages can also be left on a local tip line, 970-382-7511, or with Durango-La Plata Crime Stoppers, 970-247-1112.
The reward for clues in the case has grown to $50,450
