KINGMAN - Fire investigators could not find a cause for the June 23 fire that burned two residences in the Copper Ridge apartment complex June 23.
That's the finding of Kingman Fire Marshal Chris Weaver, who said the fire was ruled "unintentional," but how it started is a mystery.
"We know it started on the balcony of the second floor apartment," said Weaver. "We know it traveled from the balcony into the apartment and from there it burned into the downstairs apartment. You can tell by the path."
Weaver said a water heater did not explode or otherwise malfunction, which was a claim made on social media.
"All the water heaters were intact," said Weaver. Nobody was home at either apartment when the fire was called in at about 3:40 p.m.
Half of the 12 families that were displaced were able to move back in after an inspection. Weaver said modern construction regulations require a "two-hour wall" be built in the middle of apartment buildings.
"They are rated to hold back a fire for a minimum of two hours," said Weaver. "It did its job."
Once it was learned the apartments on the other side of the building were not compromised, those families were allowed to come home. Weaver said management has worked with the six families that were permanently displaced and most of them are in another Copper Ridge apartment.
