MENDOCINO COUNTY, Calif. – Just days after two people died in a fatal house fire in Potter Valley, another fatal structure occurred in Mendocino County.

Lt. Greg Van Patten of the Mendocino County Sheriff’s Office reported that the fire occurred in the 3800 block of Radical Ridge Road in Redwood Valley.

Van Patten said deputies were dispatched to the fire just after 6 p.m. Wednesday evening.

When deputies arrived they learned Cal Fire had responded to the residential structure fire at approximately 3:44 p.m., according to Van Patten.

When a Cal Fire captain first arrived the structure was completely engulfed with flames. Van Patten said the structure was destroyed.

During a subsequent investigation by a Cal Fire prevention officer, human remains were located within the burnt structure, Van Patten reported.

He said the human remains have yet to be positively identified, but investigators believe it might be the person who lived at the residence.

The investigation into the cause and origin of the fire is currently under investigation but at this time there are no obvious signs suggesting foul play, Van Patten said.

Wednesday’s fire followed by four days a fatal house fire that occurred on the morning of Sept. 29 at 10580 Main St. in Potter Valley, where two people died, as Lake County News has reported.

Anyone having information in regards to the Wednesday fire in Redwood Valley is urged to contact the Mendocino County Sheriff's Office Tip Line by calling 707-234-2100.
