>>> THE FIRST HEARING FOR THE FATHER OF THE TEEN ACCUSED OF KILLING FOUR PEOPLE AT A HIGH SCHOOL IN GEORGIA JUST WRAPPED UP. COLIN GRAY IS CHARGED WITH INVOLUNTARY MANSLAUGHTER, SECOND DEGREE MURDER AND CRUELTY TO CHILDREN. HE FACES UP TO 180 YEARS IN PRISON IF HE IS CONVICTED ON ALL OF THOSE CHARGES. HIS NEXT HEARING IS SET FOR DECEMBER 4th. TWO LAW ENFORCEMENT SOURCES TELL NBC NEWS GRAY BOUGHT HIS SON AN AR-15 STYLE RIFLE AS A GIFT. IT'S NOT EXACTLY WHEN IT WAS GIVEN TO HIM, BUT SOURCES SAY IT WAS AFTER POLICE INTERVIEWED THE TEEN AND HIS FATHER LAST YEAR ABOUT ONLINE THREATS TO CARRY OUT A SCHOOL SHOOTING. A HEARING FOR THE SUSPECTED GUNMAN WAS HELD A SHORT TIME AGO. IT'S ACTUALLY A CHILD. THE 14-YEAR-OLD IS FACING FOUR COUNTS OF FELONY MURDER. AUTHORITIES SAY HE FIRED AN AR-STYLE RIFLE INSIDE APPALACHEE HIGH SCHOOL ON WEDNESDAY, KILLING TWO STUDENTS AND TWO TEACHERS . THE TEENAGER IS NOW BEING CHARGED AS AN ADULT AND FACES LIFE IN PRISON WITHOUT PAROLE. HIS NEXT HEARING IS ALSO SET FOR DECEMBER 4th. JOINING US NOW, STATE ATTORNEY FOR PALM BEACH COUNTY, FLORIDA, DAVE ARONBERG. DAVE, I THINK THIS IS THE SECOND TIME A PARENT HAS BEEN CHARGED. IS THIS A NEW STRATEGY IN THE WAR AGAINST THESE SCHOOL SHOOTINGS? >> MIKA, SOMETHING HAS TO BE DONE. YOU'RE NOT GOING TO GET IT BY JUST CHARGING THE CHILD. WHEN YOU'RE A CHILD, YOUR BRAIN IS STILL DEVELOPING. THE THREAT OF LIFE IN PRISON MEANS NOTHING. PLUS, THEY RARELY SURVIVE. THEY USUALLY GET KILLED OR KILL THEMSELVES. IT'S UNUSUAL THAT THE KID HERE SURRENDERED. THE KEY TO CHARGING THE FATHER IS HE GAVE THE KID THE GUN AND DID NOT SECURE IT AFTER KNOWING HIS SON HAD MENTAL HEALTH ISSUES. IT'S A STRONGER CASE FOR PROSECUTORS IF YOU CAN SHOW THE FATHER DID INDEED GIVE THE KID A GUN AFTER THE FBI VISITED THE HOUSE SAYING THERE WAS A REPORT THAT THE SON WANTED TO SHOOT UP A SCHOOL. THAT WOULD BE RECKLESS DISREGARD OF A KNOWN RISK. THERE IS PRECEDENT. IN OXFORD, MICHIGAN, THE CRUMY PARENTS ARE CHARGED WITH MURDER. YOU ENGAGE IN CHILD CRUELTY AND IT LEADS TO A DEATH, I DON'T KNOW IF THAT'S AN OVERCHARGE. WE STILL HAVEN'T SEEN THE PROBABLE CAUSE AFFIDAVIT. YOU DON'T WANT TO OVERCHARGE IN A CASE LIKE THIS BECAUSE YOU'RE DEALING WITH AN UNPRECEDENTED CHARGE TO BEGIN WITH. WE RARELY HOLD PARENTS ACCOUNTABLE FOR THEIR CHILD'S BEHAVIOR IN SCHOOL SHOOTING, BUT WE SHOULD DO MORE OF THAT. >> HI. IT'S MOLLY JONG-FAST. THERE ARE A BUNCH OF DIFFERENT CHARGES. CAN YOU SORT OF WALK US THROUGH WHAT THAT LOOKS LIKE AND WHY IT'S A GROUP OF THREE? >> YEAH. THE MOST SERIOUS CHARGE IS THE SECOND DEGREE MURDER CHARGE, WHICH IS A MAXIMUM 30 YEARS IN PRISON, MINIMUM OF TEN YEARS. THAT'S FOR TWO COUNTS. THAT'S FOR THE TWO CHILDREN WHO WERE KILLED. IT DOESN'T APPLY TO THE TWO ADULTS, THE TEACHERS. THEN YOU HAVE THE VOLUNTARY MANSLAUGHTER. IT'S EXTREME RECKLESSNESS THAT LEADS TO A DEATH. IT'S NOT INTENTIONAL. THEN THERE ARE THE CHILD ENDANGERMENT CHARGES, WHICH ARE A LESSER CRIME. HE'S FACING A WHOLE HOST OF CHARGES AND RIGHTLY SO. HERE YOU HAVE A FATHER WHO INSTEAD OF BUYING HIS SON ACCESS TO A THERAPIST BOUGHT HIM AN AR-STYLE RIFLE. YOU WOULD HOPE THAT THE
