Murfreesboro Fire & Rescue Department's Fire Marshals' Office is investigating two vehicle fires at the Summit Townhomes apartment complex.

Ladder 8, Engines 1 and 4, and Rescue 8 responded to the apartments located at 2015 Empress Drive just after 4:00 Thursday afternoon.

A red Ford F-250 truck was fully engulfed in flames in front of the "X" building. Prior to their arrival, crews were told by Dispatch that witnesses on scene said they saw and heard the truck explode. It is still unclear what caused that explosion.

A silver Nissan Murano, located in front of the "N" building, was also fully involved. Crews worked quickly to extinguish both vehicles to keep them from endangering any structures.

According to Shift Commander Dale Maynard, both vehicles are a total loss. The "X" building received heat damage to the aluminum siding due to its proximity to the burning truck.

No one was injured during the incident.

Assistant Fire Marshal Carl Peas was called to the scene to investigate. According to Peas, both vehicle fires appear to be intentionally set. Peas is not releasing any further details at this time due to the investigation.
