By Russ and Tiña De Maris The Federal Bureau of Investigation wants to hear from anyone who may have information regarding this Class C motorhome. They say it was used in the massive explosion in Nashville, Tennessee, Christmas morning. Around 5:30 a.m., local time, emergency dispatchers received calls regarding shots fired in the downtown area. Responding officers found a “suspicious” RV. The rig subsequently began broadcasting an audio warning about an impending explosion, advising anyone who could hear the message to evacuate immediately. A 15-minute countdown began, which ended when the RV exploded. At least three people were injured and the blast created extensive damage to buildings in the area. A later police report stated that what may be human remains were found, but they have not confirmed any fatalities. The FBI is seeking tips on the case. Anyone with information is asked to call 800-CALL-FBI. We’ll update this story tomorrow, and as warranted. ##RVT980
