July 7th, 2019, Sergeant Dan Birbeck responded to a call at the home of a 49-year-old woman in a small Texas town. Birbeck got to the house and found a bloody crime scene in the master bedroom – evidence that a violent struggle had taken place there. Three other members of the family were home that night and had been in close proximity to the master bedroom – and none of them heard a thing. The victim’s husband had been asleep on the couch just steps away from the master bedroom. The victim’s teenage daughter was asleep in the room just next door. And the victim’s son had been in an upstairs bedroom playing video games all night. It seemed inconceivable to Sergeant Birbeck that a violent attack could have taken place in one room, while members of the family slept through it or played video games without hearing anything.
