— Fire ripped through the main floor of a split-level home in Terrace Heights on Thursday evening. No one was injured.

Firefighters arrived at the house in the 500 block of Justice Drive about 7 p.m., but with the upper floor largely engulfed in flames, they had to battle the blaze from outside, said Chief Mike Riel of Yakima County Fire District No. 4.

In all, about 25 firefighters from five departments responded. It took less than 30 minutes to get the fire under control, Riel said.

Neither of the house’s two occupants were home when the fire began.

Three dogs, however, were inside. One escaped through the front door, and firefighters rescued another dog from the lower level. The third dog, a pit bull, has not been located, and no remains have been found in the fire, Riel said. “We’re hoping that dog had also gone out” the front door.

There was no obvious source of the fire, and the Yakima County fire marshal is investigating it. Firefighters didn’t see any suspicious circumstances, though, he said.

Riel said about 65 percent to 75 percent of the house appeared to have suffered water, smoke or fire damage.

Based on the structure’s assessed value, the damages are between $103,000 and $119,000, he said.
