The Long Island Serial Killer Part 4 of 4

In today’s conclusion of our four-part coverage of the Long Island Serial Killer mystery — which has driven Mark to emphatically state that there will never be a multi-part episode again…maybe… — Lindsay and Mark explore the very very many questions that still remain more than a decade after the Gilgo Four and many other bodies began to emerge from their extremely shallow graves. Who is LISK? Was Shannon a victim of LISK? What exactly happened to make a fairly simple case so absurdly complicated that there is very little likelihood of the families of the victim having some sort of resolution in the future.
