Am still pursuing the theory that RH may have used abandoned structures in the commission of his crimes. I know this sounds far-fetched. But who thinks RH only started murdering people in 1993 at the age of 30? I don't, and I know a lot of other people don't. Did RH only start murdering people once he became a homeowner? There's no way I believe that. That means he was already committing murders (theoretically) "elsewhere," not in his home because he didn't always own that home. And his mother had been in that home pretty much up until he purchased it. If he got into the habit of using other locations earlier on (and I'm sure he did), he may have continued to use those locations in some capacity in terms of the Gilgo victims. So here are some locations I'm kind of looking into right now:
-Old Fish Cove Inn by Sandra Costilla, which cabins and had a compost heap; they filmed a movie here (slasher movie called "Madman" in 1982) with shoestring budget and had a casting call on "Backstage." RH was active in the drama club doing props and such, maybe he participated
-Pilgrim's State in Brentwood 7 mins from where they found Tina Foglia and 13 mins from Babylon/Amber, and like 13 mins from Hauppauge/Meghan Waterman
-Creedmoor in Queens, close to Flushing (Asian Doe?) and 13 min drive to Hempstead Lake State Park/Peaches & baby
-King's Park Psychiatric in Smithtown, which is incredibly close to where Nikkie Brass went to meet RH. He met her at the Steamroom Restaurant out in Rocky Point, which itself is filled with ruins of structures. Just as a note, to get from the Steamroom to Smithtown, you'd take 25A, which I've seen described as eerie, pretty desolate, and dark.
Have never been personally to any of these structures, and it's difficult to assess what the specific conditions would have been like in various timeframes, especially in terms of access. But they've all been abandoned for quite some time, and are all fairly large. And these abandoned structures come with their own interesting factors, like smells. I've always been curious about that note in HK about "M/O" and the plastic bag and cat litter. Was it to hide a distinctive smell? Because (example) Creedmoor is filled with pigeon droppings, mounds of them, and they have a pretty distinct odor. Also, his note about push pins instead of tape, yet he has another note about bringing bags and tape, and we know he ended up getting caught by tape, in part. So was that note about the push pins really in reference to the tape with hairs? Or might it have been something else? If he were using an abandoned structure, the tape might not adhere to thick dust. Agreed this theory is definitely out there in terms of what I've seen about RH (so far), but he had to have been killing somewhere early on, he didn't have a house and he wouldn't have the same privacy in an apartment. With some of these structures, he might arguably have had more privacy there than in his own home.
