So the area they were in is not at all remote. Sure, it's not as busy as an RV lot, but it's the section of beach before Padre Island National Seashore (PINS), which charges a lot more than the $12 beach permit needed most other places. People are on it 24/7, driving up and down, fishing, camping. An RV and truck in that spot is not unusual, nor would it draw attention even if it appeared deserted for a day or two. People leave their stuff and move around on the beach. A lot of people bring golf carts and take those up and down the beach. That said, this time of year, there would be plenty of time to murder someone and move bodies without anyone seeing. Since it borders a National Park, there are restrictions on lighting, it's essentially pitch black at night and it's the off-season. I don't think the perps were too concerned with the bodies being found anyway. They probably knew they would be long gone. They were in a shallow grave, which I assume means they were thrown behind the dunes and covered with some sand. Based on the pictures of the crime scene and info from my LE ranger friend, they were just over the top of the foredunes where everyone goes to pee, not back behind the big dunes where they would have been better hidden. There are tons of coyotes and badgers there that would have had access to the remains. Once you cross into PINS and pass the 0 mile marker, you're essentially on your own and that's where I would anticipate crime. The LE rangers patrol some distance, but not far unless there is a reason to. There's no cell service down there; there is cell service where M and J were parked. If someone was trying to lure them from the RV lot to the beach, they didn't send them to a great place to get away with it, obviously. If they had sent them south of the 0, it probably would have been a long time before anyone noticed. Especially this time of year. From May into September, there are turtle patrollers covering every inch of beach from Bob Hall Pier to the Mansfield Channel (~MM 60, very remote).
