Coroner waiting on autopsy results

An autopsy performed on the Cape Girardeau woman found dead in her home Saturday has not yet determined the cause of her death.

Penney Jackson, a 38-year-old mother of two, was found unresponsive Saturday afternoon by paramedics.

Toxicology test results aren't expected back for about six weeks, said Cape Girardeau County coroner Mike Hurst.

"It's a standard to send off for a toxicology report to determine the final cause of death," he said.

There were no apparent signs of foul play in Jackson's home, but investigators haven't ruled out a possible crime, chief Steve Strong said.

Jackson reportedly fell and hit her head prior to her death when exiting a car outside her home, said her brother, the Rev. Jerry Jackson of Scott City.
