GOT HOME FROM WORK PARKED MY VEHICLE IN MY CARPORT AVAILABLE SPACE IN MY APARTMENT. TURN OFF THE TRUCK COMPLETELY, NOTHING LEFT ON OR ANYTHING SUSPICIOUS TO CAUSE A INCIDENT. WHEN TO MY APARTMENT UNIT TOOK A SHOWER AND NOT MORE THAN 20-30MINS WAS ALARMED THAT MY VEHICLE WAS CAUGHT ON FIRE. I IMMEDIATELY RAN OUTSIDE TO THE CARPORT SAW THE ENGINE ON FIRE, TRIED TO STOP IT WITH ANYTHING THAT I COULD FIND (WATER HOLES) OR EXTINGUISHER. MY NEIGHBORS CALLED 911 AS I SAW THE FLAMES GETTING HIGHER AND STRONGER THE FIRE MOVED INTO MY DAUGHTERS VEHICLE WHICH WAS PARKED NEXT TO OUR OTHER CARPORT SPACE AND CAUGHT ON FIRE AS WELL. OVERALL, THERE ARE TWO VEHICLES COMPLETELY DESTROYED. THERE WAS ALSO TWO OTHER VEHICLES INVOLVED THAT HAVE SOME BURNING DAMAGES. AS WELL AS PROPERTY DAMAGES INTO OUR AVAILABLE PARKING SPACES. SOME WINDOWS FROM THE LOWER APARTMENTS WERE CRACKED. MY VEHICLE WAS PARKED INTO MY PARKING PORT, NOT IN MOTION BUT TURNED OFF COMPLETELY.
