Jacob Derr, 25, of Bastrop, Texas, was one of four people killed in a house fire on Linden Road in Del Valle on September 8, 2016. The Travis County Sheriff’s Office later concluded the deaths were homicides after finding wounds inconsistent with fire, and investigators believe the victims may have been shot before the blaze was set. Authorities have said the fire appeared to be used as a cover-up and that buying and selling of narcotics may have been a factor in the killings.

The other victims were 26-year-old Matthew Aaron Barber, 41-year-old Brian Lee Satterfield, and 53-year-old David Scott Braswell. If anyone in the Del Valle or Bastrop area has information about Jacob, the other victims, or activity around Linden Road on or before September 8, 2016, please contact the Travis County Sheriff’s Office.
