(Welcome to Websleuths!)
I disagree with Mr. Brendt that this is trophy collection. I think LISK is OCD to the nth degree. A perfectionist who cant handle anything out of place or off-symmetry.
Heres what I think: LISK knows the Oak Beach/Gilgo area and scouted this location for his first victim (Maureen) before finding and killing her in 2007. She is the first victim LISK placed on
this strip of land. His preferred disposal method is the worlds largest dumping ground: the ocean. I believe LISK is an avid winter boater, with a boat in a slip or at-the-ready all winter long. He chose an alternate land disposal site out of necessity because he wanted to avoid the throngs during boating season from Memorial Day (when people put their boats in the water) thru Labor Day (when they take them out). He is not a seasonal killer hes just cognizant about what the season means for his nocturnal activity and how he must mitigate the risk of being caught. I also believe his profession requires him to be most active and about during the May-Sep time of year and the kind of vehicle he drives would not raise suspicion if it was stopped along a desolate roadside at night.
If you use Google Earth (free download) and pin these locations youll find an interesting pattern and what has given me the impression of precise measurement. Consider this:
Bodies disposed of here:
40°37'29.22"N 73°22'31.43"W Maureen, 2007-July
40°37'27.97"N 73°22'35.80"W Melissa, 2009-July
40°37'30.28"N 73°22'28.28"W Megan, 2010-June
40°37'26.93"N 73°22'38.90"W Amber, 2010-Sept
Markers: Beginning of tree line 40°37'31.25"N 73°22'24.63"W and concrete patch (there in 2007 per GE historic image tool) 40°37'30.88"N 73°22'24.28"W
Distance from both markers:
First victim placed 0.11 m
LISK thinking: about 1/10 of a mile from concrete patch/start of tree line
Second victim placed 0.18 m
LISK thinking: not quite twice the distance of victim 1, but far enough
Third victim placed 0.06 m
LISK thinking: half the distance of victim 1
Fourth victim placed 0.22 m
LISK thinking: about 1/20 of a mile from concrete patch/start of tree line and twice the distance of first victim
For someone to remember, without notes, where he placed his victims a memory device seems the way to go. If you are familiar with this area already all it takes is to remember the turnaround in the road across from the beach (40°37'32.53"N 73°22'18.02"W) and just beyond that there is a concrete patch and the tree line starts
this is where to push the trip odometer reset button. This measurement method satisfies LISKs need for symmetry and uniformity in all that he does. The distances may not be in precise increments, but they are close enough and time is of the essence so there is risk in making them exact. The length of vehicle is also a variable. Like if LISK drove a super duty-type pickup truck, for example. Not hard to imagine something like this being extremely useful in tick-infested brush:
