An early morning explosion rocked Nashville on Christmas.
Authorities identified the suspect as Anthony Quinn Warner, 63, who died when his recreational vehicle exploded on 2nd Avenue North in the city's downtown.
Despite police having a suspect, there are many unanswered questions. Perhaps chief among them: What was Warner's motive?
Here's what we know:
8 people were injured in the blast
Police said a boxy white RV arrived at 2nd Avenue North in downtown Nashville at 1:22 a.m. (2:22 a.m. ET) Friday. They later tweeted an image of the vehicle.
Several hours later, a resident in the area said she woke up to what sounded like "an automatic weapon."
When she heard the sound again, she called 911. Police said they were called to the location after a report of shots fired around 5:30 a.m.
When officers responded to the scene, they found a white RV parked in front of an AT&T transmission building that was repeatedly broadcasting a warning that an explosion would occur in 15 minutes, police said.
A computerized voice warned residents to "evacuate now," the resident recalled.
Nashville police officers involved in the response told reporters Sunday morning that the recording changed as they were working to evacuate residents from nearby buildings, eventually giving a three-minute warning, as well as playing the 1964 song "Downtown" by Petula Clark.
The blast occurred at 6:30 a.m.
