Episode Transcript

Speaker 1 (00:00):
What if I told you that sometimes the most damning
evidence can hide in plain sight for seven years, that
a single drop of blood smaller than a pencil tip
could finally solve one of Houston's most controversial races. No
twelve year olds should have to wake up and find
out that both your parents are no longer here. When

(00:22):
I went back to school, I just kind of felt
out of my body. Really. They would talk about stuff
and I couldn't tell you what was being said because
my mind was just gone. I would think by my parents.
I would think about AJ. Did she ever ask you
point blank if you killed your parents? No? She doesn't
need to. She knows me, not a single doubt in

(00:43):
my mind. He couldn't have. Nothing could ever be said
that would make me believe that AJA kill your parents.
This is the story of a J. Armstrong, a case
that would divide juries, tear apart a community, and ultimately

(01:07):
be decided by evidence so microscopic it was nearly invisible
to the naked eye. July twenty nine, twenty sixteen, Southeast Houston.
The Armstrong family seemed to have it all. The American
dream personified Antonio Armstrong Senior, a former Miami Dolphins linebacker
who'd overcome career ending ankle injuries to build a fitness empire.

(01:30):
His Jim First Class training was more than a business.
It was his mission to transform lives. Dawn, his wife
of over a decade, was his perfect partner in business
and life. Their bel Air home was a testament to
their success, a sprawling house where family gatherings were legendary.
Antonio Junior, known as AJ, was following in his father's

(01:52):
footsteps as a star athlete, the big man on campus
who seemed destined for greatness. Twelve year old Kaira was
the family princess adored by everyone. But at one forty
a m. That perfect facade shattered with a single phone call,
BELLA one, Where's your emergency? And he chucked. The voice

(02:19):
on the other end was calm, almost eerily so. It
was Aj Armstrong reporting gunshots in his parents' bedroom. During
the sixteen minute call, there were strange pauses, barely audible whispers,
and an odd detail. Aj complained of ringing in his ears.
What the dispatcher couldn't see was the horror that awaited

(02:41):
first responders. Antonio and Dawn Armstrong shot execution style in
their bed, pillows covering their faces. The killer had been methodical,
using Antonio's own twenty two caliber pistol from his bedside
draw Dawn had been shot twice behind the ear so
to gather the wounds almost overlapped. Antonio, perhaps awakened by

(03:04):
the first shots, had been shot once in the head.
Dawn was already gone. Antonio clung to life, but would
die hours later at the hospital, never knowing his son
had been arrested for his murder. The house told a
strange story, no signs of forced entry, the security system
still armed, kitchen drawers pulled open, but nothing missing, a

(03:25):
handwritten note on the counter, I have been watching you
for a long time, and most chilling of all, Antonio's
own gun left beside the bodies. Within hours, police made
a shocking decision. They arrested the couple's sixteen year old son,
A J. Armstrong, for capital murder. Picture this. You're a

(03:45):
star high school football player, beloved by coaches, dating your
dream girl, living in a mansion. Why would you murder
your parents in cold blood? That's exactly what investigators had
to prove, and the evidence they found pain did a
disturbing picture. The security system was the prosecution's ace. Every
door and window monitored motion senses throughout the house. The

(04:08):
logs showed no external doors opening for hours before the murders,
no windows disturbed, no intruders detected. The only people who
could have been the killer were already inside the house
when the system was armed at nine fifty two p m.
Cell phone records told a chilling story. Aj had been
texting his girlfriend Kate until one o two a m.

(04:31):
When his phone was placed on the charger. At one
o eight a m. The phone was lifted from the
charger but not unlocked. One minute later, the second floor
motion detector activated. Over the next several minutes, the phone
screen turned on and off repeatedly. Prosecutors argued Aj was
using it as a flashlight to navigate the dark house.

(04:52):
The murders occurred during the only thirty eight minute window
all day when Aj wasn't actively using his phone. At
one twenty five, the living room motion censer activated when
prosecutors believe Aj planted the threatening note and gun in
the kitchen. Then silence until the nine one one call
at one forty a m. But it got stranger. Police

(05:14):
found a bullet hole in AJ's bedroom ceiling directly above
his parents room. When confronted, aj admitted he'd fired his
father's gun weeks earlier, showing off to a friend. Investigators
found bullet holes in pillows and blankets in his closet
what they believed was a practice run. Then there was
the burn mark on the carpet near the stairway reeking

(05:35):
of gasoline. Aj claimed he'd accidentally dropped a match while
playing around. Investigators theorized he was planning to block escape
routes with fire. They found an empty bottle of rubbing
alcohol in his room, and both aj and his father
had noticed a gasoline smell in the house days before
the murders. The motive text messages revealed growing tension, but

(05:58):
also something more disturbing, a pattern of manipulation. Dawn had
written about Ajay. He is a bold faced liar like
I have never seen before. She'd described feeling heart broken
by his deception, writing all you do is lie to us,
scheme behind our backs. But investigators found something even more

(06:18):
troubling in Ajay's browser history searches about inheritance laws and
life insurance policies. The family had substantial assets, and aj
stood to inherit significant wealth as the surviving sun. But
here's where it gets complicated. Other texts showed a loving relationship.
Ninety minutes before the murders, aj was texting his girlfriend

(06:41):
about love and marriage. His defense attorney would later say,
that's totally inconsistent with someone who's angry, suicidal homicidal. The
physical evidence was puzzling too, no gunshot residue on Ajay's
hands or clothes, no blood spatter, no bloody clothing found anywhere.
If a sixteen year old committed this crime, how did

(07:03):
he clean up so perfectly? Most damning was Ajay's own
nine one one call. Prosecutors claimed you could hear him
whisper about a high pitched ringing in his ears, exactly
what happens when you fire a gun without ear protection.
But a Jay had another explanation. Entirely, I saw him
running like I saw him running. Five hours after the murders,

(07:24):
a J. Armstrong told police he'd seen a masked intruder
fleeing the scene, but he hadn't mentioned this crucial detail
during his sixteen minute nine one one call. Why his
defense team had an answer. A J was protecting some one,
some one, He loved some one he couldn't bear to
see arrested entered Josh Armstrong, a Jay's older half brother,

(07:47):
Dawn's biological son from a previous relationship. In a shocking twist,
a Ja's defense attorneys pointed the finger directly at Josh
during the first trial. The evidence was compelling and disturbing.
Josh had been diagnosed with schizophrenia after the murders. He'd
been in and out of psychiatric facilities, reporting paranoid episodes

(08:08):
and violent thoughts. His ex girlfriend testified that Josh had
seemed different after returning from college, that his parents treated
him like the black sheep of the family. Most damning,
Josh's own medical records showed he'd claimed to have witnessed
his parents murders, describing details only the killer would know.
He spoke of seeing blood, hearing gunshots, and being in

(08:31):
the room when it happened. Was this a confession wrapped
in the language of mental illness. His ex girlfriend, Hannah
Pylon's testimony was devastating. She described Josh's dramatic personality change
after returning from college, his increasing paranoia, and his obsession
with perceived family favoritism. The night of the murders. Josh

(08:51):
had immediate access to the house he lived just blocks
away and had keys, But the prosecution had their own
expert testimony about Joshsh's mental state. Doctor Sarah Chen, a
forensic psychiatrist, testified that Josh's schizophrenia was likely triggered by
the trauma of his parents murders, not the cause of them.
His detailed memories of witnessing the crime were classic symptoms

(09:15):
of PTSD induced false memories, not actual recollections. Then came
another bombshell, claims that Antonio Armstrong had been involved in
a prostitution ring. Family friend Maxine Adams came forward with
allegations of shady associates, death threats, and criminal connections. The
defense argued this information had been withheld by the state.

(09:37):
Investigators found the claims unsubstantiated, but it raised questions. Days
after the murders, the Armstrong's gym was burglarized coincidence or connection.
The first trial ended in deadlock, eight jurors voting guilty,
four believing in a Ja's innocence. The second trial in
twenty twenty two also ended in mistrial, this time six

(09:58):
juras favoring acquittal. Two juries couldn't agree was a J.
Armstrong a cold blooded killer or a grieving son being
railroaded by the system. The prosecution knew they likely had
only one more chance to get justice for Antonio and
Dawn Armstrong. They went back to the drawing board and
made a discovery that would change everything. Seven years. That's

(10:19):
how long a tiny piece of evidence sat in a
police evidence room, overlooked and forgotten. After seven years of investigations, accusations,
and three trials, prosecutors say they have finally found justice
for Antonio and Dawn Armstrong. In twenty twenty three, as
prosecutors prepared for their third and likely final attempt at conviction,
blood patent analyst Sergeant Celestina Rossi made a routine review

(10:42):
of the physical evidence. She was examining AJ's shirt from
the night of the murders when something caught her eye.
A visitor's badge, the kind police stations put on civilians
during questioning. It had been stuck to A J's shirt
when he was first brought in for questioning. Rossi pealed
back the sticker and found something extraordinary, tiny reddish brown

(11:04):
stains on the adhesive backing A J. Armstrong's T shirt
was retested after authorities said flakes of blood were discovered
under a Houston Police Department visitor's badge he wore the
night his parents were murdered in twenty sixteen. The preliminary
tests indicated blood, but whose blood. The sample was rushed
to the Houston Forensic Science Center for DNA analysis. The

(11:27):
results were stunning, a single source match to Antonio Armstrong Senior.
How did Antonio's blood get under that sticker? Rossi had
a theory that would horrify the court room. When Antonio
was shot, his lungs filled with blood. As he struggled
to breathe, tiny droplets of blood were expelled and landed
on his killer. Droplets so small they were nearly invisible,

(11:50):
each about the diameter of a mechanical pencil tip. They
stayed there until this sticker was placed on there, which
preserved those stains. Rossi would later testify the defense was blindsided.
Defense attorney Rick D. Toto later said the timing was suspicious.
Why was this crucial evidence discovered just before the third trial.

(12:12):
After consulting with AJ and multiple attorneys, they made a
calculated decision they would let the evidence in rather than
appear desperate by fighting it. De Toto argued cross contamination,
pointing out that evidence had been handled by dozens of
people over seven years. He questioned why no other blood
was found on AJ's clothing, skin, or hair if he'd

(12:34):
been close enough to be splattered during the shooting. But
Sergeant Rossi had answers. She explained that the droplets were
so small they were drying even as they flew through
the air. When they landed on AJ's shirt, they didn't
soak in. They sat on the surface like tiny scabs
until the visitor's badge trapped and preserved them. The prosecution
argued this wasn't just blood evidence, it was proof Aj

(12:57):
had been present when his father was dying, close enough
to be touched by Antonio's final desperate breaths. But the
prosecution finally had their smoking gun. In twenty twenty three,
the third trial concluded with a unanimous decision finding a
j Armstrong guilty of the murder of his parents. This
verdict came after more than ten hours of deliberation, marking

(13:18):
the end of a tumultuous and lengthy legal journey. A
j Armstrong, now twenty four, showed no emotion As the
verdict was read, Judge Kelly Johnson immediately sentenced him to
life in prison, with the possibility of parole after forty years.
As bailiffs led him away in shackles, his grandmother, kay Winston,
collapsed in sobs, crying out they got the wrong person.

(13:42):
The conviction brought mixed reactions from the community. Antonio's former
NFL teammates expressed relief that justice had finally been served.
Dawn's family, who had remained largely silent during the trials,
issued a statement saying they could finally begin to heal,
but others question whether justice had truly been done. Criminal

(14:03):
defense attorneys across Houston criticized the prosecution's reliance on evidence
discovered seven years after the crime, calling it unprecedented and
potentially dangerous for future cases. I believe I'll be acquitted.
Aj Armstrong told KPRC two in an exclusive prison interview.
Even after conviction, he maintains his innocence, insisting the blood

(14:26):
evidence was planted. Armstrong has already filed a notice of appeal,
and he filed a civil lawsuit against the City of Houston,
accusing police of planting blood evidence to sway this third jury,
But the story doesn't end there. In May twenty twenty four,
AJ's case took another dramatic turn that could potentially overturn

(14:47):
his conviction. The Harris County District Attorney's office informed Armstrong
that his case may be associated with a forensic analyst
who was terminated for faulty work. The fired analyst, whose
identity hasn't been publicly released, had worked on DNA evidence
in dozens of cases over several years. An internal investigation

(15:09):
revealed pattern of contaminated samples, mishandled evidence, and potentially falsified results.
Defense attorneys across the county began filing motions for new
trials based on this revelation. Armstrong's legal team immediately seized
on this development. They filed an emergency motion arguing that

(15:29):
if any evidence in their case was handled by this analyst,
the entire conviction should be thrown out. Their demanding access
to all lab records and chain of custody documents related
to the blood evidence that convicted their client. Meanwhile, Armstrong's
personal life has crumbled. His wife, Kate, who stood by
him through three trials and testified in his defense, filed

(15:51):
for divorce in December twenty twenty four, court documents revealed
the strain of his conviction, mounting legal bills, and the
impossibility of maintaining a marriage with someone serving life in prison.
Their young son, now old enough to ask questions, has
been told his father is away at work. Kay Winston
AJ's grandmother, who has been his most vocal supporter, broke

(16:14):
down during a recent interview that baby asks for his
daddy every day. How do you explain to a child
that his father is in prison for something we know
he didn't do. The divorce proceedings have been contentious, with
disputes over Armstrong's limited assets and the rights to his story.
Kate has reportedly been approached by several production companies interested

(16:35):
in her perspective on the case, though she has declined
all offers. A j Armstrong's request for a new trial
has been denied by the courts, but his appeals continue
through the system. The case that captivated Houston for nearly
eight years refuses to quietly fade away. Loo
