An occupant was found dead inside a home following an extra-alarm fire Saturday evening near Wonder Lake, authorities said.

The Wonder Lake Fire Protection District and McHenry County Sheriff’s Office responded around 10:13 p.m. Saturday to the 8000 block of West Route 120 in unincorporated Woodstock for a report of a structure fire.

The sheriff’s office received several 911 calls from people passing by that saw a house on fire, according to Wonder Lake Fire Chief Mike Weber.

Firefighters arrived and found the east side of the residence engulfed in flames that were approximately 10 feet above the roof, Weber said.

The blaze had extended from the first floor to the second floor of the residence and the home quickly became heavily engulfed in fire.

“We tried to make contact with any homeowners, everything was locked up and were unable to get inside,” Weber said.

The Mutual Aid Box Alarm System (MABAS) was activated to the second alarm level to bring additional firefighters and water tenders to the scene due to a lack of fire hydrants.

Firefighters pulled a hose line to extinguish the fire while other firefighters attempted to do an immediate search.

The heat inside the home was around 1,600 degrees and firefighters were unable to get inside.

The homeowner was initially unaccounted for and firefighters later located a deceased person inside the residence. An autopsy is being scheduled by the McHenry County Coroner’s Office.

The blaze caused approximately $300,000 in damage and left the home a total loss.

The fire does not appear to be suspicious in nature but it is under investigation by the Office of the Illinois State Fire Marshal, Wonder Lake Fire Protection District and the McHenry County Sheriff’s Office.
