NORWICH – Two Coventry residents have been arrested after they allegedly set fire to their own home Aug. 13, in a blaze that destroyed the two-story house and all their possessions.

A number of area fire departments responded to the 10:20 p.m., Friday night fire after a neighbor called 911.

Firemen found the unoccupied home engulfed in flames when they arrived. Within a few hours, fire investigators inspecting the building’s debris found evidence of foul play and contacted the Chenango County Sheriff’s Office.

Lt. Richard Cobb said police spoke with the home’s owner at the time and received conflicting information about the incident. Cobb said they began a criminal investigation into the fire and sent away evidence for testing.

The fire investigation was recently completed and the findings indicated the fire was started in the home’s first floor using a liquid accelerant, possibly gasoline, Cobb said.

Police have charged the homeowner, 36-year-old Kimberly Koster and another unidentified 17-year-old female, who was also living at the residence, with third-degree arson and fourth-degree conspiracy, both felonies.
