>> Narrator: AS A LAST RESORT, POLICE LOOKED ONE MORE TIME AT
THE CRIME SCENE.
IT WAS CLEAR THERE HAD TO BE ANOTHER CAR AT THE SCENE.
>> Narrator: SO WHO WOULD HAVE HAD THE MOTIVE AND THE
OPPORTUNITY TO COMMIT THIS CRIME?
KARYN'S EX-HUSBAND, MICHAEL, HAD AN ALIBI FOR THE NIGHT OF THE
MURDER, BUT HIS PARENTS DID NOT.
THEY WERE THE ONES WATCHING KARYN'S SON, CHRISTOPHER, ON THE
DAY OF THE MURDER.
>> Narrator: 51-YEAR-OLD JEANNETTE SLOVER DETESTED HER
EX-DAUGHTER-IN-LAW, KARYN.
AND EVERYONE KNEW HOW MUCH SHE LOVED HER 3-YEAR-OLD GRANDSON,
CHRISTOPHER.
>> Narrator: IN FACT, SHE TOLD FRIENDS THAT, AFTER CHRISTOPHER
WAS BORN, SHE BEGAN BREAST-FEEDING HIM.
INVESTIGATORS CHECKED TELEPHONE RECORDS AND DISCOVERED THAT
MICHAEL JR. CALLED HIS PARENTS 12 TIMES ON THE WEEKEND OF THE
MURDER.
ALSO SUSPICIOUS -- THE SLOVERS OWNED A USED-CAR LOT JUST ONE
MILE FROM THEIR HOUSE.
THE LOT, PATROLLED BY TWO JUNKYARD DOGS, WAS ALWAYS DIRTY
AND IN DISREPAIR.
JUST AFTER KARYN DISAPPEARED, NEIGHBORS SAID THE LOT GOT A
MAKEOVER.
>> Narrator: WAS IT POSSIBLE THEY WERE TRYING TO REMOVE
SOMETHING CONNECTED TO KARYN'S MURDER?
TO FIND OUT, INVESTIGATORS CONTACTED RICHARD MUNROE, A
WELL-KNOWN FORENSIC GEOLOGIST.
CONCRETE AND CINDERS WERE FOUND WITH KARYN'S BODY.
COULD HE TELL IF THEY CAME FROM THE SLOVERS' CAR LOT?
BOTH SAMPLES WERE PLACED IN A SCANNING ELECTRON MICROSCOPE AND
HIT WITH HIGH-ENERGY RADIATION.
>> Narrator: THIS ENABLES THE IMAGES OF THE SAMPLES TO BE
MAGNIFIED UP TO 5,000 TIMES THEIR ACTUAL SIZE.
VISUALLY, THE SAMPLES LOOKED SIMILAR.
MUNROE THEN GROUND THE SAMPLES INTO A POWDER AND BOMBARDED IT
WITH X-RAYS TO IDENTIFY THE CHEMICAL MAKEUP OF THE SAMPLES.
MUNROE CONCLUDED THAT THE MATERIAL FOUND IN THE BAG WITH
KARYN'S BODY AND THE MATERIAL FROM THE CAR LOT WERE SIMILAR
ENOUGH TO RAISE SUSPICIONS.
BUT INVESTIGATORS NEEDED MORE THAN THAT.
AND TO GET IT, THEY TURNED TO AN UNLIKELY SOURCE -- THE
UNITED STATES ARMY.
>> Narrator: MORE THAN TWO YEARS AFTER KARYN SLOVER'S MURDER,
INVESTIGATORS NOW SUSPECTED THAT HER EX-IN-LAWS WERE INVOLVED.
THE MOTIVE -- KARYN'S FORMER MOTHER-IN-LAW, JEANNETTE, WANTED
SOLE CUSTODY OF HER 3-YEAR-OLD GRANDSON.
>> Narrator: INVESTIGATORS FOUND NO FORENSIC EVIDENCE INSIDE THE
SLOVERS' HOUSE, BUT CONCRETE FROM THEIR USED-CAR LOT WAS
CONSISTENT WITH CONCRETE FOUND IN THE GARBAGE BAGS WITH KARYN'S
BODY.
INVESTIGATORS WANTED MORE PROOF AND WENT TO UNUSUAL LENGTHS TO
GET IT.
THEY CALLED IN THE ARMY TO HELP THEM REMOVE ALL THE TOPSOIL FROM
THE SLOVERS' 5,000-SQUARE-FOOT CAR LOT.
DURING A LATE-WINTER SNOWSTORM, 60 5-GALLON BUCKETS WERE FILLED
WITH MATERIAL.
FOR SIX PAINSTAKING MONTHS, TEAMS OF INVESTIGATORS SIFTED
THROUGH THE DEBRIS.
FINALLY, THEY FOUND A POTENTIAL CLUE -- A BUTTON THAT READ
"AUTHENTIC PARIS SPORTS CLUB."
THE JEANS KARYN WAS FOUND IN HAD THE EXACT SAME BUTTONS.
>> Narrator: FURTHER SIFTING REVEALED SOME RIVETS WHICH WERE
ALSO CONSISTENT WITH KARYN'S JEANS.
THEN INVESTIGATORS FOUND A DIFFERENT TYPE OF BUTTON.
IT WAS CLOTH-COVERED PLASTIC, THE TYPE USED ON SHIRTS AND
BLOUSES.
>> Narrator: SCIENTISTS TOOK A FIBER FROM THE BUTTON ON KARYN'S
BLOUSE AND PLACED IT UNDER A COMPARISON MICROSCOPE.
>> Narrator: THE NEXT THING WAS TO IDENTIFY THE WEAVE PATTERNS
ON BOTH BUTTONS.
>> Narrator: BOTH BUTTONS WERE THE SAME SIZE, MADE OF THE SAME
MATERIAL, COVERED WITH THE SAME FABRIC, WITH AN IDENTICAL WEAVE
PATTERN.
FINALLY, THE SLOVERS HAD TWO DOGS, AND SCIENTISTS WONDERED IF
THE HAIR ON THE DUCT TAPE CAME FROM ONE OF THEM.
>> Narrator: ONLY ONE OF THE SIX DOG HAIRS FROM THE DUCT TAPE
PROVIDED ENOUGH DNA FOR AN ANALYSIS.
>> Narrator: JEANNETTE AND MICHAEL SLOVER SR. AND THEIR
SON, MICHAEL JR., WERE ALL CHARGED WITH FIRST-DEGREE MURDER.
MICHAEL JR. WAS CHARGED BECAUSE HE AIDED HIS PARENTS IN THE
PLANNING AND COMMISSION OF THE CRIME.
THE MOTIVE -- THE SLOVERS WERE AFRAID KARYN WOULD MOVE OUT OF
STATE, DEPRIVING THEM OF TIME WITH CHRISTOPHER.
BASED ON THE FORENSIC EVIDENCE, PROSECUTORS BELIEVE KARYN WENT
TO THE SLOVERS' CAR LOT TO PICK UP HER SON.
DURING THE DISMEMBERMENT, BUTTONS FROM HER BLOUSE AND
JEANS FELL ON THE GROUND.
AND THEY USED CEMENT AND CINDERS FROM THEIR LOT TO GIVE WEIGHT TO
THE PLASTIC BAGS CONTAINING KARYN'S BODY.
SOME OF THE DOG HAIR STUCK TO THE TAPE THEY USED TO CLOSE THE
GARBAGE BAGS, AND ITS DNA MATCHED THE SLOVERS' DOG.
THEY DUMPED KARYN'S BODY INTO LAKE SHELBYVILLE AND ABANDONED
HER CAR ALONG A DESERTED HIGHWAY.
BUT THE FORENSIC EVIDENCE LINKED THE SLOVERS TO THE MURDER IN
EVERY IMAGINABLE WAY.
>> Narrator: ALTHOUGH MICHAEL JR. WAS WORKING AT THE
TIME OF THE MURDER, HE CALLED HIS PARENTS 12 TIMES THAT
WEEKEND AND HELPED CLEAN UP THE
CRIME SCENE AFTERWARDS.
PROSECUTORS WERE CONVINCED HE WAS ACTIVELY INVOLVED IN
PLANNING THE MURDER AND COVER-UP.
THE THREE SLOVERS WERE ALL CONVICTED OF FIRST-DEGREE MURDER
AND SENTENCED TO 60 YEARS IN PRISON.
