The La Plata County Sheriffs Office made the announcement on Wednesday, along with the announcement that Redwines cause of death had been changed from unknown to homicide.
Redwine, then 13, disappeared from his fathers home in the La Plata County town of Vallecito in November 2012. Some of his remains were discovered in the summer of 2013.
That (person of interest) designation was based on evidence collected, inconsistent statements made by Mark Redwine, and his behavior throughout the investigation, the sheriffs office wrote in a press release.
The La Plata County Sheriff also indicated on Wednesday that Dylans mother, Elaine Hall, her son Cory Redwine, and Elaines husband, Mike Hall were cleared of any involvement in Dylans disappearance and death.
