Authorities have not released causes of death for 26-year-old Matthew Aaron Barber of Del Valle, plus three Bastrop men — 25-year-old David Scott Braswell, 25-year-old Jacob Derr and 41-year-old Brian Lee Satterfield.
Officials say the victims had wounds not consistent with death by fire. A sheriff's department statement Monday said evidence indicates the buying and selling of drugs was a key factor leading to the deaths.
No arrests have been announced.
