That can't be true because he was inside Brian Albert's house and Karen Read wasn't there. It's why three witnesses saw Karen alone in her car, it's why John's Apple health data shows him going up and down 3 flights of stairs around that time and Karen's phone doesn't, it's why 8 eye witnesses didn't see his body on the front lawn with less than an inch of snow, it's why Dr. Loposata testified that nothing on the front lawn could've caused the injuries to John's head but several things inside the house could've, it's why multiple doctors testified that John had dog bites on his arm, it's why Proctor avoided interviewing multiple witnesses inside the house (Levinson, Nagel, Albert Jr, Caitlin Albert, Colin) before indicting Read, and it's why Ian Whiffin testified that John and Jen's location data showed he could very easily be inside the house.
