It depends from which road they entered from.
As you exit Hwy 27 onto Lake Streety Rd towards the lake, the road first points SW, then directly West for a small stretch, then NW along the lake itself, until finally beyond the lake the road turns due North for a long stretch until it hits Otto Polk Rd.
Looking at the satellite map, it’s seems to me they were somewhere along the lake itself, meaning NW would be entering the scene and SE would be leaving - headed back out to Hwy 27.
(Closer to Hwy 27 the road is surrounding by groves on either side, which I don’t see in the police pics).
But then again, if they entered onto Lake Streety Rd from Otto Polk Rd (and not Hwy 27) then South would be approaching the scene, and North would be exiting.
Given the distances to the lake, it seems more likely they entered from Hwy 27.
...I hope all that made sense. To someone. Maybe some eagle-eye out there can pinpoint exactly where on the road they were. But regardless, my money is on DT facing out and BR/KS facing in.
EDIT: After taking another look, it’s almost certain the position of the trucks (the crime scene) is along the lake itself.
No other part of the road matches the photos - although I cannot find the traffic sign that I clearly see in the pics. Maybe it’s new...
But they were RIGHT ON the lake, so DT could’ve been parked and had started fishing when trouble started for all we know. ...my 2 cents
