Having seen the last video of Steven there are two things I can tell you. One for certain, the second highly likely.
1) Definitely he had been there before!
2) Most likely it was a business related rather than a social meeting.
Why? As a sales director of many years I have accompanied hundreds of thousands of salesmen on sales visits. You can just instantly tell if the salesman has been to a place before from how he acts and walks. For example, Stevens car did not cruise hesitantly up and down the street looking for exactly where to go. There was no gradual peering at door numbers or stop starting. He also knew without worrying where he could easily park nearby.
Then as he walks away from the car he knows EXACTLY where he is going and again there is no checking door numbers to find how far he is from his destination. These are just the obvious indicators, but there is also the feel that comes with years of experience of doing this. I KNOW when a colleague is kidding me about where he has and hasn’t been in the past. Steven had been there before! (It may be irrelevant, or you may profit by going further back on your CCTV or other records)
The second point. Why was it business related? Well he waited six minutes in his car. That’s what you do if you are visiting a business appointment. I have done it with my guys all my life. You get there early, wait in your car until a few minutes before the appointment and then walk in the door with a couple of minutes to spare. If it is a social call, you pull up in their driveway or outside the house and go straight in.
That second point is also another indicator that he had been there before. He could judge the journey time to arrive six minutes before the appointment. He did not arrive there half an hour in advance.
You bring up a lot of good points! Thank you!!
I have always believed that he parked in that spot because he was instructed to park there, away from the location where he was supposed to meet this other person. also, if he was walking a block or two to get into another car, then he'd have no reason to be looking at house numbers at all.
Excellent point.
Additionally, in many new neighborhoods there are rules about parking on the street. Do we know if that was true in this neighborhood? If it was, it makes sense why Steven parked so far from his destination, wherever it was. Maybe the cul-de-sac was a designated area to park.
