"He has not mentioned anything about this other matter to me," Belser said.
Whited had a string of arrests for traffic and drug offences through the years including one for possession of a crack cocaine pipe less than three weeks after two hunters found Dailey's body with a gunshot to the head on April 26, 1995, documents show. The victim's vehicle was found partially submerged in the Tennessee River.
Without a suspect and no information that could lead to one, detectives kept following leads without any success. Then, on Wednesday, a detective answered the phone.
In a sworn statement, Investigator Sean Mukaddam said he initially spoke to Whited, who agreed to show police the crime scene.
"Detectives met with Whited who re-enacted the crime to detectives and provided corroborated information about the murder," the statement said.
Authorities said Whited and Dailey did not know each other and declined to discuss a motive, but Mukaddam said Whited is "terminally ill," the New York Times reported.
While police sometimes make public appeals for information to help resolve old cases, that had not happened with Dailey's killing. Authorities said it was not clear what prompted the call from Whited, who was jailed for the killing, with bail set at $15,000.
