I HAVE A 2007 H2 HUMMER THAT WAS IN MY DRIVEWAY YESTERDAY AND MY NEIGHBOR NOTICED THAT IT WAS ON FIRE. IT WAS SITTING THERE WITH NO KEYS IN IT, TURNED OFF, NOT EVEN GONE ANYWHERE THE WHOLE DAY. IT LOOKS LIKE IT STARTED BEHIND THE DASH OR BACK OF THE ENGINE COMPARTMENT. IT IS COMPLETELY DESTROYED. DO YOU WANT THIS VEHICLE FOR YOUR INVESTIGATION? THANK GOD IT WASN'T IN MY GARAGE OR MY KIDS WEREN'T IN IT. *TR
