A fire that spread through three "tall and skinny" homes in Nashville on Pecan Street was arson.
Spencer, Nashville's arson dog, alerted investigators to an "incendiary substance" at the scene.
Firefighters responded to the large fire in North Nashville Tuesday night in the 1700 block.
According to fire officials, no injuries were reported. All three homes were in various stages of construction at the time of the fire.
Friday, arson investigators confirmed the fire was incendiary. Further details were not immediately available. The exact cause of the fire remained under investigation.
Justin Thomas lives right across the street from the homes that burned down.
"Honestly, I'm surprised we haven't had more issues down here with just how fast some of this neighborhood's changing and some of these people have grown up on this street," he said. "We haven't even had graffiti issues. None of the homes down that way were messed with, none of the homes down that way were messed with. This is the first thing we've seen from it."
