It could be next month before authorities know what caused the death of a 40-year-old north Forsyth woman whose body was found inside her burning home early Easter morning.

Elise Jeanette Chrisley was dead when firefighters discovered her at 5145 Shady Grove Road.

Forsyth County Fire Division Chief Jason Shivers said Chrisley’s autopsy was completed by the Georgia Bureau of Investigation on Monday, but the results won’t be released to local authorities until the toxicology report is also concluded. That process is expected to take about three weeks to a month.

And it’s not known if the information would be released to the public at that time.

The cause of the fire also remains under investigation, according to Shivers.

Forsyth County has had one fatal fire a year over the past three years. Sunday’s was the first of 2013.

In November 2012, a 64-year-old man was found dead in a burning mobile home off Sawnee Drive.

And in April 2011, three people died in a blaze on Little Mill Road in north Forsyth.

The fire Sunday was reported by a passer-by about 1:08 a.m. Chrisley was alone in the house at the time, Shivers has said, and the smoke detectors were working.

The blaze caused extensive smoke and water damage, making the home uninhabitable.
