Investigators with Washington County and the Tennessee Bureau of Investigation determined Sells to be the suspect and found that Sells and Robert Vaughn had been communicating with each other on the night of the shootings.

Officials say the exact motive is still under investigation. They believe that Sells took several personal items of Robert Vaughn’s from the home following the shootings.

Investigators determined that the shootings took place on the 3rd of December and were not discovered until the 4th. The two children were inside the home by themselves for over a 24 hour period.

Authorities say Sells has been charged with three counts of first-degree murder, three counts of felony murder, unlawful possession of a weapon, aggravated robbery and aggravated child neglect.

On Saturday, December 9th, after developing Sells as the prime suspect, Washington County Investigators worked with the Sullivan County Sheriff’s Office to conduct surveillance on Sells. Sells was found to have an active violation of probation out for his arrest and was stopped and arrested by Sullivan County Sheriff’s Office.

Authorities say Sells had a handgun under the driver’s seat of the vehicle he was operating at the time. Sells was charged in Sullivan County with violation of probation, possession of a firearm by a convicted felon, and simple possession of marijuana. Sells was incarcerated in Sullivan County with no bond.

According to police, investigators seized several items in relation to the homicide after searching Sells' home.

Arrangements will soon be made for Sells to be booked into the Washington County Detention Center where he will be held by Washington County on a $1,000,000 bond pending an arraignment in Criminal Court.
