After breaching the room, police found the husband and two boys — ages 5 and 10 — “lying in bed, all with gunshot wounds,” according to the statement.
They also found a woman, “lying on the floor with an apparent gunshot wound to her head,” the statement reads.
“The female and one of the children were unresponsive but still appeared to be alive and were subsequently transported to UTMB where they were both later pronounced dead.”
Investigators say the family, who lived in Baytown, Texas, checked in only hours before their deaths.
“Forensic data collected at the scene indicates that the female is believed to be the shooter at this time, and is believed to have killed her two children and her husband before apparently taking her own life with a 9mm handgun found adjacent to her body,” the statement explains.
