   GUNSHOT WOUND.
   >> Reporter: DID THEY 
   MENTION 
   THAT IT WAS A DEPUTY 
   THAT HAD 
   SHOT HIM?
   >> NOT AT THIS POINT.
   NO ONE SAID ANYTHING.
   NO ONE SPOKE TO UP SAY
   AN 
   OFFICER SHOT MY CHILD.
   >> Reporter: IT WAS 
   MARCH.
   HER SON, 14-YEAR-OLD 
   WAS IN THE HOSPITAL.
   HE HAD BEEN RIDING 
   WITH A GROUP 
   OF FRIENDS IN A CAR 
   THAT HAD 
   BEEN REPORTED STOLEN.
   THOUGH, McGEE SAYS HE 
   DIDN'T 
   KNOW THAT.
   DEPUTIES TRIED TO STOP
   THE CAR.
   THE DRIVER STOPPED AND
   THE THREE 
   TEENAGERS STARTED 
   RUNNING.
   McGEE JUMPED THIS 
   FENCE AND 
   DEPUTIES CAUGHT UP 
   WITH HIM AS 
   HE TRIED TO CRAWL 
   UNDERNEATH 
   THAT SHED IN THE 
   BACKYARD. 
   >> Reporter: DID YOU 
   REALIZE THAT THE 
   OFFICERS HAD DRAWN 
   THEIR WEAPONS?
   >> UHN-UHN. 
   >> Reporter: WHERE DID
   SHE SHOOT 
   YOU?
   >> IN MY BACK. 
   >> Reporter: THE 
   ORIGINAL NEWS 
   REPORT DID NOT MENTION
   THE 
   OFFICER-INVOLVED 
   SHOOTING.
   THREE MONTHS LATER 
   JAMAL WAS 
   CHARGED WITH RESISTING
   AN 
   OFFICER BY FLIGHT.
   >> I WOULD LIKE 
   ANYBODY TO BE ABLE TO 
   COME MOVE. 
   >> Reporter: IN HIS 
   ONLY PUBLIC STATEMENT 
   ON
   THE INCIDENT, THE 
   SHERIFF SAID 
   THE AGENCY WAS 
   INVESTIGATING.
   >> JUVENILE RECORDS 
   ARE PROTECTED A LITTLE
   BIT DIFFERENT.
   TRUTHFULLY, I DIDN'T 
   KNOW IF IT WAS 
   REPORTED OR NOT 
   REPORTED THREE MONTHS 
   AGO.
   >> Reporter: BUT 
   TIFFANY McGEE 
   SAYS SHE STRUGGLED TO 
   GET 
   ANSWERS ABOUT WHAT 
   HAPPENED THAT 
   NIGHT. 
   >> WE HAVEN'T HAD ANY 
   OFFICER-INVOLVED 
   SHOOTINGS. 
   >> Reporter: SHE 
   RECORDED WHAT 
   SHE SAYS WERE HER 
   INVOLVEMENT 
   WITH THE SHERIFF'S 
   DEPARTMENT. 
   LIKE THIS ONE IN MAY. 
   >> WITH A FIREARM, 
   SIR.
   MY SON HAS A BULLET 
   WOUND
   THAT IS NEVER GOING TO
   GO AWAY.
   AT 14 YEARS OLD.
   YOU'RE GOING TO LOOK 
   IN MY FACE 
   AND TELL ME YOU DON'T 
   REMEMBER.
   NO.
   THAT DIDN'T SET WELL 
   WITH MY 
   SPIRIT.
   SO IT WASN'T ABOUT TO 
   JUST STOP 
   THERE. 
   >> Reporter: SHE IS 
   NOW ONE OF 
   SEVERAL FAMILIES IN 
   THE PARISH 
   CALLING FOR CHANGE.
   NBC NEWS FOUND THAT
   IN THE LAST FIVE 
   YEARS, AT LEAST 
   12 BLACK AND LATINO 
   MEN AND BOYS 
   HAVE DIED IN 
   ENCOUNTERS WITH THE 
   SHERIFFS OFFICE.
   BUT THE SHERIFF HAS 
   REJECTED 
   CALLS TO USE BODY 
   CAMERAS CITING 
   CAUSE, A KEY REFORM 
   THAT 
   NEIGHBORING NEW 
   ORLEANS HAS 
   EMBRACED. 
   >> ABSOLUTELY NO 
   JUSTIFICATION 
   FOR IT. 
   >> Reporter: RONALD 
   HALEY IS 
   REPRESENTING THE 
   FAMILY. 
   >> DEADLY FORCE SHOULD
   ONLY BE 
   USED IN THE MOST 
   EXTREME CASES.
   AND I'M SORRY, A 
   14-YEAR-OLD 
   CHILD LAYING ON THE 
   GROUND 
   TRYING TO COMPLY IS 
   ABSOLUTELY 
   OBJECTIVELY NO REASON 
   TO USE 
   DEADLY FORCE AT ALL.
   >> Reporter: WHAT DO 
   YOU SAY TO 
   THE PEOPLE LOOKING AT 
   THIS CASE 
   WHO MIGHT THINK, OKAY,
   BUT WHY 
   DO YOU RUN?
   >> RUNNING ISN'T A 
   DEATH 
   PENALTY.
   THERE IS NO 
   JUSTIFICATION FOR 
   SHOOTING AN UNARMED 
   CHILD IN THE 
   BACK.
   THERE ISN'T.
   THERE ISN'T. 
   >> Reporter: THE 
   SHERIFFS OFFICE 
   DECLINED OUR REQUEST 
   FOR AN 
   ON CAMERA
   INTERVIEW, CITING 
   CHILD PRIVACY 
   LAWS.
   THE OFFICE DECLINED TO
   ANSWER QUESTIONS ABOUT
   POLICIES AND IN 
   CUSTODY DEATHS.
   TIFFANY McGEE SAYS SHE
   WON'T 
   STOP PUSHING. 
   >> ONCE I GET ME A 
   VOICE AND LET 
   IT BE HEARD, I'M GOING
   TO LET IT 
   BE HEARD. 
   >> Reporter: ONE 
   MOTHER WHO 
   WOULD NOT STAY SILENT.
   GABE GUTIERREZ, NBC
   >>> IN THE SEARCH FOR 
   SOLUTIONS, 
   A NEW KIND OF TEST FOR
   COVID-19 
   NOW IN TRIALS WHICH 
   COULD GIVE 
   VIRTUALLY REAL-TIME 
   RESULTS.
   HERE'S NBC'S VILLA 
   MARX.
   >> Reporter: TONIGHT 
   WITH PEOPLE 
   IN SOME STATES FACING 
   LONG WAIT 
   TIMES TO GET RESULTED 
   FROM 
   COVID-19 TESTS, COULD 
   A NEW 
   SOLUTION BE A TEST 
   THAT WORKS 
   LIKE A BREATHALYZER?
   >> IT IS A LOT MORE 
   EFFICIENT.
   IT'S ALMOST REAL-TIME,
   THE 
   RESULTS.
   IT'S A LOT CHEAPER, 
   AND IT'S A 
   LOT MORE CONVENIENT.
   >> Reporter: IN 
   FINLAND, 
   SCIENTISTS ARE 
   DEVELOPING WHAT 
   COULD BE A GROUND 
   BREAKING NEW 
   APPROACH THAT DELIVERS
   RESULTS 
   ALMOST IMMEDIATELY. 
   >> Reporter: WHAT IS 
   THE 
   ADVANTAGE OF YOUR 
   TESTING 
   TECHNIQUE?
   >> OUR BIGGEST BENEFIT
   IS THE 
   SPEED.
   WE CAN PROVIDE ALMOST 
   REAL-TIME 
   SOLUTION
   BECAUSE OUR 
   TURN-AROUND TIME IS 
   JUST TWO MINUTES. 
   >> Reporter: NANO 
   SENSORS DETECT 
   DIFFERENT GASES THAT 
   OUR LUNGS 
   PRODUCE, IDENTIFYING 
   THINGS IN 
   OUR BODIES JUST LIKE A
   BLOOD 
   TEST.
   OVER THE NEXT MONTH, 
   THE COMPANY
   HOPES TO CONFIRM THE 
   GASES AND 
   THEIR LEVELS THAT 
   CORRESPOND TO 
   POSITIVE COVID 
   PATIENTS EVEN IF 
   ASYMPTOMATIC.
   PROTOTYPES ARE 
   SHIPPING ACROSS THE 
   WORLD TO GATHER MORE 
   DATA.
   A SIMILAR TECHNIQUE 
   USED IN THE 
   PAST DEVELOPS A 
   SUCCESSFUL TEST 
   FOR TUBERCULOSIS.
   THE HOPE, THIS COULD 
   SOLVE A GLOBAL TEST NG
   ING DILEMMA AROUND 
   COVID-19.
   >> THERE IS NOT ENOUGH
   TESTING 
   CAPACITY TO TEST THE 
   MASS 
   POPULATION IN A SHORT 
   TIME 
   FRAME.
   WE ARE OPENING UP THAT
   BOTTLENECK. 
   >> Reporter: RECENT 
   RESEARCH 
   SUGGESTS BREATHALYZERS
   ARE 
   FASTER, CHEAPER AND 
   MORE 
   ACCURATE THAN SWAB 
   TESTS.
   THE COMPANY SAYS IT 
   WILL FIND 
   OUT FOR SURE WHEN 
   TRIALS FINISH 
   IN ABOUT FOUR WEEKS 
   TIME.
   LESTER?
   >> ALL RIGHT.
   THANK YOU.
