MY FRIEND (26 YEAR OLD MALE) WAS DRIVING MY 2004 LEXUS RX330 AT AROUND 9AM ON CHRISTMAS EVE MORNING. WITNESSES STATE THAT HE WAS TRAVELING SOUTH ON A RESIDENTIAL STREET AND CROSSED A BUSY 6-LANE DIVIDED ROADWAY AT 80 MPH. HE CONTINUED ON THE RESIDENTIAL STREET AT WHICH TIME HE LEFT THE ROADWAY AND VAULTED ACROSS AN EMBANKMENT HITTING A BLOCK WALL. HE WAS KILLED INSTANTLY. PIMA COUNTY SHERIFF AND MEDICAL EXAMINER INVESTIGATED AND COULD FIND NO REASON FOR THE EXCESSIVE SPEED OR THE COLLISION. NO DRUGS OR ALCOHOL WERE FOUND IN HIS SYSTEM AND HE HAD NO MEDICAL PROBLEMS. I HAVE NO DOUBT NOW THAT I HAVE READ OTHER REPORTS THAT SOMETHING WAS MECHANICALLY WRONG WITH THE LEXUS AND THAT CAUSED THIS FATAL ACCIDENT; UPDATED 003/30/10 *BF *TR UPDATED 06/30/10.*JB UPDATED 9/29/11*CW
