Derrick Benjamin Sells

WASHINGTON COUNTY, Tenn. (WJHL) -- Washington County Sheriff Ed Graybeal said on Tuesday afternoon that a man has been arrested and indicted by a Washington County grand jury in the Boones Creek triple murder case, according to WJHL.

Derrick Benjamin Sells, 33 of Fall Branch, TN, is facing multiple charges in the shooting deaths of Kyanna Vaughn, 23, and Robert Vaughn, 25.

Earlier this month, Graybeal said that Kyanna Vaughn and her husband, Robert Vaughn, were found dead in their home on Friendship Court. Deputies also found their two children, a girl and a boy, ages three and six, unharmed inside the home.

Investigators found that Kyanna Vaughn was six months pregnant at the time, which made it a triple homicide investigation. A WCSO news release revealed that Sells, a suspect at the time, had been communicating with Robert Vaughn the night the shootings took place.

The sheriff's office said a motive to the shootings remains under investigation, but said it is believed that Sells took several of Robert Vaughn's items after the shootings.

Investigators believe the shootings took place on December 3, but the Vaughns were not discovered until December 4. Their two children were reportedly inside the home alone for more than 24 hours.

After Sells was developed as a suspect, WCSO investigators along with the Sullivan County Sheriff's Office, conducted surveillance of him on December 9.

Sells reportedly had an active violation of probation from Sullivan County and was stopped and arrested by SCSO deputies. Investigators say they found a handgun under Sell's driver's seat. He was charged in Sullivan County with Violation of probation, possession of a firearm by a convicted felon and simple possession of marijuana.

He was jailed in Sullivan County without bond.

After his arrest, investigators served a warrant at Sell's home on Branch Road in Kingsport and seized multiple items related to the homicide. The items were then sent to the Tennessee Bureau of Investigation for testing.

Working with the District Attorney, Tony Clark, a special grand jury was called on Monday morning to present the case for indictment.

Sells was charged with three counts of first-degree murder, three counts of felony murder, unlawful possession of a weapon, especially aggravated robbery and aggravated child neglect.

Sells will be booked into the Washington County Detention Center, where he will be held on $1 million bond pending his arraignment in Washington County Criminal Court.
