Robert Aaron Vaughn, 25, was found shot dead inside his Johnson City mobile home on Friendship Court on December 4, 2017. His wife, Kyanna Howes Vaughn, 23 and six to seven months pregnant, was also found dead; their two children, ages 6 and 3, were unharmed and discovered in the residence.

Investigators identified Derrick Sells of Damascus, Tennessee, as responsible for the killings. He was charged with three counts of felony murder, felony robbery, and felony child neglect. Sells later pleaded guilty to felony murder under a plea agreement and received life in prison with the possibility of parole after 50 years.

The scene reflected a family life—children’s toys remained outside and an American flag flew on the porch—and the deaths had a profound effect on relatives and neighbors. Does anyone have information about the Vaughn family or about that Friendship Court neighborhood in 2017?
