Yes, and you have to wait for a green arrow in order to turn left into HT.
Okay so I will say 8 minutes from Wallsburg Court to HT going across Lochmere - should be conservative enough since we aren't rocket scientists here.
So what we have if a person is to transport a body from Wallsburg Ct to the recovery location - there are two ways to get to that location. One way, vehicular traffic is to be expected. The other way - very minimal vehicular traffic until one goes between Lily Atkins and Fielding on Holly Springs Rd. Keeping in mind our person was moving slow and looking at houses.
Wallsburg Ct to Lochmere to Kildaire to HT - 8 minutes
Disposal routes
Route One - traffic encountered Wallsburg to Cary Pkwy to Holly Springs to Fielding to recovery site to HT
4 minutes Wallsburg to Cary Pkwy to Holly Springs to Fielding
3 minutes Fielding to recovery site
3 minutes recovery site to HS RD/Fielding
2 minutes HS Rd/Fielding to Lily Atkins to Lochmere
3 minutes Lochmere/Lily Atkins to Lochmere/Kildaire
3 minutes Lochmere/Kildaire to HT
Total 18 minutes - add one minute to THROW body = 19 minutes
Route Two - minimal traffic encounter -Wallsburg to Lochmere to Lily Atkins to Holly Springs to Fielding to recovery site to HT
3 minutes Wallsburg to Lochmere/Lily Atkins
2 minutes Lochmere/Lily Atkins across HS Rd to Fielding
3 minutes HS Rd/Fielding to recovery site
3 minutes Recovery site to Fielding/HS Rd
2 minutes Fielding/Holly Springs to Lily Atkins/Lochmere
3 minutes Lily Atkins Lochmere to Lochmere/Kildaire
3 minutes Lochmere Kildaire to HT
Total 19 minutes - add one minute to THROW body = 20 minutes
Taking either of these routes - a person would have time to leave the home, dump a body, and go to the store in a maximum of 20 minutes and return back to the house in a total expired time of 28 minutes - roughly.
Two trips to HT - one to dump a body and one just to go to the store total time roughly 48 minutes - add a few minutes to grab a couple of things and one still has time to accomplish all of this in one hour or less.
