Episode Transcript

Speaker 1 (00:00):
Hey, listeners, it's your favorite rookiy on the beat, Detective
Emily M. Carter coming at you live from the precinct
with a steaming cup of coffee and a stack of
files that could bury a suspect. I'm the twenty six
year old, fresh out of the academy, still buzzing from
all those late night Our phone call is Firestar, and
let me tell you, the streets are talking louder than

(00:20):
ever this December. And let me tell you the streets
are talking louder than ever this December twenty twenty five.
Are you sure? No? We can stay over there? You
know me. I live for diving into the darkest corners
of the criminal mind, breaking down patterns that make your
skin crawl. In tonight, we're zeroing in on the hottest
serial killer stories, ripping through the headlines, no fluff, just

(00:42):
the raw facts, my academy trained analysis, and a dash
of that sarcasm that keeps me sane after a twelve
hour shift. We've got identifications cracking open cold cases in Toronto,
indictments piling up on Long Island, charges dropping in New Mexico,
and a wave of unsalved homicides in DC that has
me pacing my tiny apartment wondering if there's a shadow

(01:05):
killer lurking in the nation's capital. Buckle up, because we're
going deep, over four thousand words deep into what's shaking
the true crime world right now. Let's kick this off
with a bombshell out of Toronto, because if there's one
thing that gets my criminology heart racing, it's genetic genealogy.
Finally nailing a monster who's evaded justice for nearly a decade.

Speaker 2 (01:28):
Picture this listeners three women, Christine Prince twenty five, Claire
Sanson twenty three, and Graycelind Greenwich forty one, all homicide victims.
They're lives snuffed out by the same hand. Police just
identified Kenneth Smith as the serial killer behind it all,
and the announcement hit like a freight train on December eleventh,

(01:52):
twenty twenty five. Smith was working in Toronto during the murders,
with a prior history of sexual assault that should have
had read flags waving like crazy. Back in twenty sixteen,
a genetic link tied Prince in Samson's cases to one
unknown male offender, and by twenty seventeen, the Center of
Forensic Science confirmed the same dnap O file across all

(02:15):
three homicides. Fast forward to twenty twenty five, and investigators
used cutting edge familial DNA searching to pinpoint close relatives
of the offender, leading to that conclusive match on Smith.
Now as a rookie who spent hours in the academy
lab mocking up DNA profiles. This is textbook justice evolution.

(02:37):
Remember when we relied on eyewitnesses who could pit the
wrong guy out of a line up thirty percent of
the time. Genetic genealogy flips that script, tracing family trees
through public databases to smoke out suspects. Smith's case screams
organized offender, someone who targeted vulnerable women, likely with the
sexual sadism modive layered under control fantasies. His assault history

(03:00):
classic escalation pattern, straight out of my sight textbooks where
petty crimes ramp up to lethal violence. Toronto Police Service
investigators deserve a standing ovation for not letting this go cold.
They built a profile, chase the science, and bone closure
for families who've waited years. But here's my rookie take.
What if Smith wasn't acting alone. Accomplices in serial cases

(03:23):
happen more than Hollywood admits, and with three vicks over years,
I'd be canvassing his old co workers, pulling phone records
from twenty sixteen listeners. If you're in Toronto, keep your
eyes peeled, because monsters like this don't vanish without leaving echoes,
shifting coasts to Long Island, where the Gilgo Beach serial
killings just keep unfolding like a nightmare you can't wake from.

(03:46):
And December twenty twenty five brought fresh charges that have
me glued to my desk. Rex Huerman, the architect turned
alleged monster, now faces indictments for seven murders stretching back
to the early nineteen nineties. On December fifth, twenty twenty five,
Andrew Diykes got charged in connection with two more victims,

(04:06):
Tanya Jackson and their daughter, Tatiana Dykes. Hireman's raptut includes
Amber Lynn Costello, Megan Waterman, Melissa Barthelmy, Maureen Brainerd Barnes,
Sandra Costilla, Jessica Taylor, and Valerie Mack with please not
guilty across the board. The timeline exploded in June twenty

(04:29):
twenty four, when he was arraigned for Taylor and Costilla murders.
Not even originally linked to Giglow, pushing the spree back decades.
Then January twenty twenty four added BRAINERD Barnes, December twenty
twenty four hit with Mack, and April twenty twenty five
saw police id the remains of Jackson and Dykes. This

(04:52):
case is a master class and victimology and a fender
persistence hireman, a family man by day, a ly hunted
sex workers, dumping bodies along Ocean Parkway like discarded blueprints.
His profile white male, mid fifties to sixties, high functioning
job masking paraphilic disorders, probably power assertive type with ritualistic

(05:15):
elements in the bindings and disposal sites. Academy instructors hammered
this home cereals often live double lives, blending in until
DNA or a pizza receipt cracks them. Harriman's arrest stemmed
from that receipt traced to his office, plus burner foam
things and hair evidence refined by modern mitochondrial DNA. But

(05:36):
Dykes's charts. That's the twist. A familial angle, maybe father
daughter victims pointing to intimate partner violence escalating to serial territory.
As a cop on patrol. I've seen domestic calls turn
deadly fast, and this reeks of rejection fueled rage spilling over.
Suffolk County PD's task force is grinding, releasing updated sketches

(05:59):
of Asian dome OZH in September twenty twenty four. Task
forces are far from life where they keep up with
whatever they want. Hireman's architecture background makes me think of
those precise body dumps like failed construction projects. Listeners, Long
Island beaches will never feel the same, and justice here
could redefine cold case protocols nationwide. Now, let's head southwest

(06:24):
to New Mexico, where federal charges just stacked higher on
Labar to Teflekai, an alleged serial murderer, kidnapper, and sexual
abuser whose case screams disorganized chaos meets calculated evil. The U. S.
Attorney and FBI announced additional charges in this ongoing code painting.
A picture of a predator preying on the vulnerable, likely

(06:48):
Native communities, given the jury mandates, Given the jury
