I keep thinking that L-guy may not have even entered the house, but was the driver and his partner was in the house doing whatever he ( or she) was doing with NG. L-guy readied the front door to bring NG out. If he did go inside, it may have been to help carry NG out, if she was unable to walk because she was incapacitated. There HAD to be a vehicle nearby, maybe near the garage? All just speculation, as usual. JMO
