I WAS TRAVELING FROM LAS VEGAS, NV TO TWIN FALLS, ID WITH MY SON [XXX] ON DEC 14 2015 TO VISIT FAMILY FOR CHRISTMAS. MY SON [XXX] WAS A WEEK FROM TURNING 4, WEIGHED 37 LBS AND WAS 38 INCHES TALL. I HAD HIM IN THE BABY TREND HYBRID 3 IN 1 LX (KIWI COLOR) FORWARD FACING IN THE 5 POINT HARNESS. AT AROUND 9PM MOUNTAIN STANDARD TIME ON DEC 14 2015 MY SON [XXX] WAS ABLE TO PULL THE SLACK ON HIS HARNESS LOOSE AFTER UNCLIPPING HIS CHEST CLIP AND FREED HIS UPPER ARMS. THE MOMENT I NOTICED HE HAD DONE THIS OUR SMALL CAR WAS HIT HEAD ON BY A PICKUP TRUCK THAT WAS DRIVING AT A HIGH RATE OF SPEED. SINCE [XXX] LOWER BODY WAS THE ONLY THING RESTRAINED HIS UPPER BODY WAS THROWN FORWARD AT A HIGH RATE OF SPEED WHICH CAUSED A HYPER EXTENSION AND SEVERANCE OF HIS SPINAL CORD AT THE C3- C4 VERTEBRAE. [XXX] PASSED AWAY AT THE SCENE OF THE CRASH WITHIN SECONDS. ...UPDATED 04/19/16 *BF SEE ALSO 10859748 *DSY.....UPDATED 05/24/16 *BF UPDATED 09/19/2017 *JS INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR
