BLUEFIELD, WV (WVNS) — On July 15 at 4 a. m., Bluefield Police and Fire Departments responded to a house fire on Highland Ave, but nobody was home.

Perhaps the most perplexing detail in this case was the state of the home following the blaze. Bluefield Police Detective, Devon Williams, is investigating the fire.

“The structure of the house is actually fine. A lot of the items inside, of course, were burned and destroyed,” Williams said. “Bluefield Fire did a good job and actually saved the residence so, the residence is still standing and didn’t burn completely.”

What was puzzling officials even further is it wasn’t just one specific flame that sparked in the early hours of Monday morning. Officials said the fire started in multiple areas of the house, as well as on both floors.

At this time, it is unclear how the fire started, although a sign posted on the house offers a reward for information.

“$5,000 for a lead or information leading to the capture of individual or individuals involved in possibly setting the fire or had any connection to the fire,” Williams said.
