UPDATE: Fire destroys home south of Little Rock

LITTLE ROCK, AR - Deputies call an early morning house fire in Pulaski County "suspicious." Neighbors tell police they heard an explosion before flames engulfed the house at 1100 Russenberger Road.

"It's unusual to us," said Lt. Timothy Hibbs. "Normally you don't hear an explosion reported."

It's not the only unusual thing about the fire either, according to deputies. For starters, explosions are commonly associated with gas. This house doesn't use gas.

Here's another curious aspect to the story: deputies say David Kincade owns the home. They arrested him in Jaunuary because they say he shot his wife in the head. She survived the shooting and is now separated from her husband. Deputies say that may - or may not - have something to do with the fire.

"Could it be related to other issues? Maybe," said Hibbs. "Couldn't really say with any certainty."

It means for the moment, deputies have more questions than answers. They say they did see evidence in the rubble that could suggest criminal activity but won't say what that evidence is.

Said Hibbs, "I would hesitate to say, or try to characterize the cause of the fire at this time. There are some suspicious elements to it."

Deputies say David Kincade shot his wife in the head and then pushed her out of their front door in January. A judge ordered Kincade to be held on $200,000 bond. Deputies say Kincade made that bond and was released from jail on February 16th.

This is an ongoing investigation. If you know anything about the cause of the fire -- you're asked to please call the Pulaski County Sheriff's Office.
