Episode Transcript

Speaker 1 (00:00):
Listeners. Detective m Carter here, badge still warm for my
morning shift, and trust me, I have not had enough
coffee for the cases we're about to wad into. You
came for the newest, wildest news in the world of
serial killers, and let me tell you there has been
no shortage of headlines lately. My boots are barely off,
my head is spinning with forensics, and every time I

(00:20):
look at a fresh headline, I'm reminded why my academy
notebooks are full of post its marked expect the unexpected.
Let's not waste time. Let's dive straight into the heart
of this darkness, combing through the biggest serial killer stories
making headlines across America right now. My fellow rookies and
seasoned detectives alike, you're going to want to keep your

(00:41):
notebooks handy for this one. So you want to talk
about Rex Huerman, Oh, you know you do. If you
have not followed the twisted saga of the so called
Gilgo Beach serial killings, buckle up. This case has haunted
New York law enforcement for over a decade, and now
it is back with new indictments, fresh for twenty twenty
five Keywerman, a fifty nine year old architect from Nassau County,

(01:04):
was arrested last summer in midtown Manhattan, blind siding everyone
from his suburban neighbors to seasoned homicide detectives. Charged initially
with the murders of Melissa Barthelmy, Megan Waterman, and Amber Costello.
He even got named the prime suspect in the Mourning
Brainer Barnes killing, which is pretty much the equivalent of
your intro class final exam going open dash book halfway through,

(01:26):
and just when you think this case is finally closing,
it opens right back up. In June twenty twenty four,
Huerman was arraigned for the murders of Jessica Taylor and
Sandra Costia. The kicker. Costilla's murder had never previously been
linked to this series. Suddenly our timeline jumped backward, stretching
into the early nineties. Then in December twenty twenty four,

(01:48):
another twist, Huerman indicted for the two thousand murder of
Valerie mack Folks. This is the definition of a cold
case coming back like an ork winter, brutal, unrelenting, and
full of bury secrets. Huerman has pleaded not guilty on
all counts so far, and as of this moment, he
is the prime suspect in a monstrous series of murders

(02:08):
that has shaken Long Island to its core. One. It
is not lost on me or my fellow detectives that
this case has serious dexter level drama. The FBI profile
from way back in twenty eleven pug the killer as
a white male mid twenties to mid forties, intimately familiar
with the south shore of Long Island, and get this,

(02:28):
using burlap sacks to dispose of bodies. If you are
sitting at home thinking that's oddly specific, you're not wrong.
That level of detail is what the academy calls a signature,
and signatures get you caught. Investigators also haven't ruled out
the possibility there's more than one killer working the same
stretch of coastline. Just imagine the task force meetings on

(02:50):
this one. Layers of theory, forensics, cross check, and not
enough coffee in the world. Huerman's background reads like a
suburban nightmare. Home and Massipeka Park, architectural career in Manhattan, wife,
two kids, His daughter even worked at his firm. You've
heard it before. The one, he was so normal chorus

(03:10):
from the neighbors, the stunned family portrait. Yet the real
break in the case came in twenty twenty two, when
police finally traced a dark green first generation Chevy Avalanche
to Huerman. A detail of witness remembered from years back,
that listeners is why you never dismissed the old interview logs.
Every rookie hears it in training. The devils in the

(03:32):
details and details catch killers. One. Let's shake the snow
globe a little. We are not just talking solved cases
and known suspects. Here. America is still home to active,
unidentified serial killers. These cases hang over communities like a
bad dream that just will not quit. You ever heard
of the I seventy Killer. If you grew up in

(03:55):
the Midwest and the nineties, you probably remember checking the
locks twice before close up shop. The ICE seventy Killer's
reign began in Apri nineteen ninety two, targeting petite brunettes
working alone in stores off Interstate seventy. He would come in,
wait for a quiet moment, and execute his victims with
a small caliber weapon, always at the back of the head.

(04:18):
The stores were robbed, but it was clear violence was
the real purpose. There have been witness sketches, age progressed composites,
the works he may have struck in Texas in the
early nineties and even in Indiana in two thousand and one.
This killer is a ghost, no suspects, no credible leads,
and no closure for the families. And then there is

(04:40):
the haunting reality. As of twenty twenty five, eleven serial
killers are believed to still be at large in the
United States. Not all are headline names. Some cases have
gone ice cold, and some are burning with fresh forensics
and social media speculation. But the pattern is the same.
Enforcement is always five steps behind, chasing shadows, piecing together

(05:05):
evidence from scenes that often look like the aftermath of
a tornado, made of fear and despair. Here's a rookie's perspective.
The hardest part is knowing just how normal everything feels
on the surface. You walk into some of these crime scenes,
and except for the tape and the tension, you'd think
you were anywhere. But you get a whiff of that
chemical tang, see the way the detective's faces turn granite,

(05:29):
and realize you're standing in a place where someone's darkest,
most violent impulses just rewrote the story of a family
and a community forever swatching gears. Let's zoom out and
look at some of the new faces in the courtroom
this year. If you've got a calendar, circle the major
trials of twenty twenty five, one that's got the true

(05:49):
crime forums buzzing is the case against Brian Coberger in Idaho.
Coburger is facing charges for the murder of four University
of Idaho students, a case that has all the hall
marks of a classic serial murder, methodical, shocking, and sending
ripples far beyond the local news. Prosecutors are seeking the
death penalty, and if you are following the trial, keep

(06:11):
your eyes on the forensics and digital evidence. In today's world,
your phone is like a second witness and the way
