On Saturday, December 30, three males were found dead inside of a hunting trailer in Brownwood.
Brown County Sheriff Vance Hill suggested that the cause of death was likely carbon monoxide poisoning from a heater within the trailer.
In addition, the trailer did not have ventilation.
The bodies were later identified as John Glass, Sr., 69; Bryan Glass, 41; and Cody Glass, 13.
The three men were related as grandfather, father and son.
