Thursday night I joined Josh Zeman to go through what I think is one of the more interesting rabbit holes surrounding Rex Heuermann.

An old online account using the name LongIslandAndy has left behind a pretty strange digital trail. Some of what we found lines up in ways that are difficult for me to ignore. There are numerous overlaps with Gilgo, The Killing Season, Amber Costello, Amber’s sister Kim Overstreet and Other pieces leave legitimate questions.

To be clear, we have NOT confirmed that LongIslandAndy was Rex Heuermann. That distinction matters. But we have actionable items in okay to move the needle towards confirmation

But if this account can eventually be connected to Rex, the implications are pretty incredible. It would potentially give us a window into what he was reading, where he was online, and possibly how closely he was following discussion surrounding Gilgo before his arrest.

There is another layer that I find fascinating.
Josh made The Killing Season, probably the most well-known documentary examining the Long Island Serial Killer case before Rex’s arrest. If LongIslandAndy really was Rex, then while Josh was publicly hunting for answers about the unidentified killer, Rex may have been somewhere in that same online world watching people search for him.

We go through what we found, what actually matches, what doesn’t, and where I think we need to be careful.
I’m curious what Reddit finds as well. Watch it skeptically. Try to poke holes in it.

I’m watching episode 8 of the killing season documentary right now and I’m wondering if there is any evidence that Rex Heuermann was in contact with John Robert Williams.

In the documentary, Williams claims to have a pen pal who lived Massapequa park who confessed to him that he was responsible for the Gilgo beach murders. Was this possibly Rex or is more likely that Williams (or someone else) was bullshitting?

According to Williams his penpal claimed to have been questioned by the police which lines up with what the user LongislandAndy said on UtopiaGuide.

Edit: I made this post before finishing the episode. I don’t think it was Rex but it is a strange coincidence. It seems like the pen pal they find in the documentary was the right person who lied about being lisk.

I'm just curious. I remember when they were probably very close to, or already had, identified her in Oct. 2022, she was connected to an Elijah "Lije" Howell of Mobile, Alabama. It did turn out she was from Mobile, but being that her surname is not Howell, I'm wondering if anyone was able to figure out what the connection was there.
