Everything we know about the investigation into 12-year-old girl’s death, parents’ arrest in Atascosa County
"On Aug. 16, the sheriff’s office said an autopsy indicated that Sipps
“experienced a trauma to her neck.” The agency is still awaiting the Medical Examiner’s final report. [Sheriff] Soward said the injuries were life-threatening and put her in a state of unconsciousness."
"Sheriff David Soward said the couple may not have wanted law enforcement at their house because it was “unkempt.” The sheriff’s office said, “Sipps was kept on a homemade bedding area in an environment that was not kept to a reasonable standard of cleanliness. She’d been in that situation, laying on the floor for four days.”"
