I think it's very possible he saw the killer leave. Not only his vehicle, but it is quite possible he actually passed him on foot without even realizing he was the killer. Watching these videos makes me believe that this was probably a robbery and he was probably looking for money. What we can never figure out is why he didn't leave. Maybe his plan was to rob every customer who came in the store and he figured as long as the women were bound and gagged they were not a threat to him and could not call police. Maybe the accomplice, and I'm convinced there was an accomplice, was not only looking out for the police, but maybe alerting him of possible customers about to enter the store.
I would think if the Target call came in around 10:30, the officer probably arrived about three minutes later. The accomplice sees the police car and thinking what if a customer goes into the LB store and manages to escape and flags down this officer. At that point, this person in the SUV tries to tell him let's get out of here as it is too risky now with a police officer only a couple of football fields away. This is most likely the reason he left that back room, because something was going on out front and he went to check it out. By this time RM gets her hands free, calls 911 and we know the rest. He probably bolts out the back exit, goes around to the front and casually gets into this SUV, or possibly his own car and leaves before anyone realizes who he was.
I do not believe all four customers were in the store when he arrived. I believe maybe one was in there when he arrived and another came in shortly after. The last two probably came in one at a time over the next few minutes. I know there was a report he may have fought with one of them. Maybe he didn't expect any customers to be there at that time due to the early hour and the bad weather. Me living in Florida, I'm not too familiar with how snow affects morning shopping, but I would think if it was really cold and snowy there would likely be less customers at that time of day.
