A Medford fire that damaged a home's basement while the owners were out of town over the weekend appears to have extinguished itself, possibly because of a water line it burned through, fire officials said.

"It either stopped itself or got help from that water. We're just not sure yet," said Medford Fire-Rescue battalion chief Brian Fish.

Fire officials said the owners of 1301 E. Main St. arrived home around 7:20 p.m. Monday to find their home full of soot and smoke. They called 911, fearing a fire. Fire crews responded with a full structural response, four engines and about 15 personnel.

First responders found no actual fire, but did find evidence that one had started and burned itself out. Fire damage was confined to about 25 percent of the basement, which also had been flooded by about four inches of water, still leaking from a severed line.

"That water was spraying all over the basement," Fish said.

There was also additional smoke damage throughout the house. Fire officials do not believe the blaze's cause is suspicious. It remains under investigation.
