THIS WEEK MARKS THE ANNIVERSARY OF ONE OF THE MOST FAMOUS UNSOLVED MURDERS IN NEW MEXICO HISTORY. IT'S CLASSIFIED AS A COLD CASE -- BUT AS YOU'RE ABOUT TO SEE -- POLICE HAVE NOT GIVEN UP ON TRACKING DOWN THE KILLER. JOE VIGIL IS LIVE IN THE NEWSROOM WITH TONIGHT'S TOP STORY. THEY WERE GUNNED DOWN IN COLD BLOOD IN THEIR LINCOLN COUNTY RANCH HOME. THEIR MURDER IS THE OLDEST COLD CASE ON THE STATE'S WEB SITE. LOOKING THROUGH OLD MURDER AND MISSING PERSON CASES--- STATE POLICE INSPECTOR SCOTT FORD KNOWS THEY'RE CONNECTED TO FAMILIES. 'We understand the toll it takes on a family specifically when they've had no closure they have no answers to what happened.'STATE POLICE WANT TO PROVIDE THOSE ANSWERS--SPECIFICA LLY IN THE CASE OF THOMAS 'COTTON' MCKNIGHT AND JUDY MCKNIGHT. TWO NAMES THAT HAVEN'T BEEN HEARD FOR QUITE A WHILE IN LINCOLN COUNTY. 'We have not forgotten about the investigation 24 YEARS AGO THIS SATURDAY--ON NOVEMBER 15TH, 1984--- AUTHORITIES FOUND THEIR BODIES ON THEIR SOUTHEASTERN LINCOLN COUNTY RANCH. SOMEONE SHOT THEM. EVEN AFTER ALL THIS TIME POLICE KNOW SOMEONE OUT THERE HAS ANSWERS. 'Whoever committed the crime more than likely has discussed it with somebody has left a trail of some sort... and maybe someone needs to get that information off their chest.'THE MCKNIGHT CASE IS JUST ONE COLD CASE LISTED ON THE DEPARTMENT OF PUBLIC SAFETY WEBSITE. THEY HOPE PEOPLE LOOK AT THESE CASES--AND CALL IN TIPS. LIKE THE MURDER CASE OF JANIS PULLIAM. AUTHORITIES FOUND HER BODY AT ELEPHANT BUTTE LAKE IN 1989. AND THERE'S THIS JANE DOE CASE OF 2000. TARGET SHOOTERS DISCOVERED THE WOMAN IN HER MID 50'S....SOUTH OF I-40 NEAR NINE MILE HILL. WHO KILLED HER AND WHY? POLICE HOPE YOU CAN HELP THEM FIGURE THAT OUT. 'We're aware of the pieces of the puzzle that we have so far, they may hold the piece we don't.' WE'LL LINK YOU TO THE DPS WEBSITE AT KOB.COM. JUST CLICK ON FOUR LINKS. ALSO---STATE POLICE DISBANDED A COLD CASE UNIT A FEW YEARS AGO BECAUSE OF STAFFING ISSUES. THERE'S NOW TALK ABOUT STARTING THAT UNIT BACK UP. A CONSTRUCTION WORKER IS IN THE  « Less
