Metro police spokesman Don Aaron said police received a report of a suspicious vehicle and upon investigating the report, officers called the hazardous devices unit. When the unit responded to the area, the vehicle exploded.
Witnesses told investigators they heard gunshots early in the morning and a message coming from an RV parked in the street warning anyone in the area to evacuate. Officers said they are looking into these reports.
