Authorities in Tennessee are searching for a man they say called 911 claiming he was being chased by a bear, leading first responders to a body and sparking a manhunt for the caller.

The incident began on October 18, when a man called 911 claiming to be a hiker in distress, according to a news release Friday from the Monroe County Sheriff’s Office in Tennessee. The caller identified himself as Brandon Andrade and claimed he fell off a cliff while running from a bear.

When first responders arrived at the scene in Tellico Plains, they found a dead man with identification belonging to Andrade, according to the sheriff’s office. But investigators soon determined the body was not Andrade and that Andrade’s ID had been “stolen and used on multiple occasions,” the sheriff’s news release said.

The dead man has not yet been identified, according to the release. Investigators are currently working to develop a sketch of the victim to release to the public to help identify him.

Investigators discovered that Nicholas Wayne Hamlett, 45, of Alabama used Andrade’s identification and that he was wanted in Alabama for a parole violation, the sheriff’s office said.

Authorities have since issued an arrest warrant for Hamlett for first-degree murder. He is considered “armed and dangerous,” according to the news release. The sheriff’s office advises anyone with information about the case to share it and call 911 if they see Hamlett.

The sheriff’s office is working with the FBI, Tennessee Bureau of Investigation and other agencies to identify the victim and locate Hamlett, the release said.

CNN has reached out to the Monroe County Sheriff’s Office in Tennessee for more information.

Tellico Plains, where the victim was found, is a small town in East Tennessee with a population of just under 1,000 people.
