He testified that he was the third officer to arrive on scene and heard three shots as he walked up to the house.
The prosecution played dashcam from his patrol car that showed officers outside the home and Layne coming out of the home, where she was taken into custody.
Tash said when he went inside he saw a black handgun near the front door, and blood splattered throughout the house on walls, in the kitchen and basement.
When the defense cross-examined Tash, they asked him if he was able to say where the shots he had heard came from or if he could tell who had fired them. He said he could not.
