Hi PrairieWind!
Yes, there were texts that indicated their marriage was in trouble. I'm not so sure if she was worried about him leaving her or if she was beginning to think of leaving him. Can't put a finger on it, but there was something in one or two of those texts that, JMO, implied he had been violent before. I saw no discussion or evidence about the husband's BAC that night. Not sure if they took it or not.
Some of the important evidence was security company records showing when their front door was opened and closed. The ME stated that the severity of Kat's head injury (blunt force trauma that was powerful enough to force her brain down onto her brainstem) meant that she would have been rendered unconscious immediately. He said the blood was mostly in a pool under and around her head. He said the force of the blow was greater than if she had fallen (she was only about 5 ft tall) . LE believed that someone opened the front door and threw Kat's phone outside. She went out to retrieve it. He followed her and hit her on the side of her head while she was picking up the phone.
Also, the young witness who found Kat, who was on her way to work early that morning noticed the husband pacing back and forth in front of the living room window. The witness called 911 and told them about the husband. She said that he could see his wife outside in the street and wondered why he wasn't calling 911.
