ON THE NIGHT OF 5/11 I CAME HOME FROM A BUSINESS TRIP IN A RENTAL VEHICLE AND PULLED MY PERSONAL VEHICULAR OUT OF MY UNDERGROUND SECURED GARAGE TO TAKE TO A STORE APPROXIMATELY 1 MILE AWAY. AFTER RETURNING TO MY APARTMENT I PARKED THE VEHICLE IN THE OUTSIDE PARKING LOT JUST FOR THAT NIGHT AS I PARKED THE RENTAL UNDERGROUND. ABOUT 15 MINUTES AFTER PARKING MY VEHICLE I HEARD 2 LOUD BOOMING SOUNDS I COULD HEAR FROM MY APARTMENT. ABOUT 20 MINUTES AFTER THE BOOMING SOUNDS THREE POLICE OFFICERS CAME TO MY APARTMENT DOOR AND TOLD ME MY VEHICLE WAS ON FIRE. THEY TOOK ME DOWN TO THE PARKING LOT AND TOLD ME THERE WAS AN EXPLOSION THAT LED TO THE FIRE. THEY TOLD ME THERE WAS A WITNESS WHO SAW SPARKS FLYING WHICH LED THE POLICE DETECTIVE AND FIRE DEPARTMENT TO THINK IT WAS AN ELECTRICAL ISSUE THAT LED TO THE EXPLOSION. THERE IS A POLICE REPORT ON FILE AND I HAVE FILED A CLAIM WITH MY INSURANCE. THE ENGINE COMPARTMENT WAS COMPLETELY ENGULFED IN FLAMES AND THE HEAT/FIRE DAMAGED THE TWO VEHICLES ON EITHER SIDE OF MY VEHICLE.
