You could be right. The Blvd. would make a lot more sense as far as being on his route, but the news story cited in the first message of this thread, plus several subsequent MSM reports, say it was Sanctuary Way. However, it's also even harder to imagine nobody would drive past for two hours on a more major thoroughfare like Sanctuary Blvd.
Also, I noticed there are some strip malls and several businesses several blocks east on Jacksonville Dr. It might be where the truck video came from, but that's just a wild guess. More info on the video here:

@vls12345, the crime scene, as shown on this news video, looks more like it is the Blvd., as you suggest.
