Two people are dead after an apparent double murder in Carter County, Tennessee.

The bodies were discovered around 11:30 a.m. Tuesday morning by one of the victim's sons. According to officers, the victims' mobile home was burned down about three weeks ago.  Police say it was arson.

The two had been living in the garage where their bodies were found.

The scene is located on Hemlock Lane, which is off Hampton Creek Road in the Shell Creek community on Roan Mountain.

The bodies were found in a partially burned garage. A TBI spokesperson says they had been shot to death before the building was set on fire in an apparent attempt to cover up the murders.

One person living next door says he didn't hear anything over night and his dogs didn't bark.

The victims have been identified as Joyce Brock and Glenn Shell. Neighbors say the couple had lived there for many years and are stunned someone wanted to kill them.

An investigator close to the case says one of the victim's sons is currently in federal custody on drug charges and is a suspect in a shooting investigation in the Roan Mountain community from a few weeks ago.

The investigator says that while the son is obviously not the shooter, they are working to see if there could be any connection to the other cases.

The Tennessee Bureau of Investigation has been called into help.
