EAST PRAIRIE, MO (KFVS) - There has been no foul play found after a death investigation south of East Prairie, Missouri.
According to the Mississippi County Acting Sheriff Branden Caid, the investigation began around 4 p.m. on July 11. The autopsy in Farmington, Mo was on Friday, July 13.
According to the medical examiner, the woman's death was not a homicide.
An autopsy showed the woman possibly died from exposure to the elements due to the heat outside. The toxicology reports are pending. Her son, found in the home, died from a heart attack.
According to Caid, the woman, born in 1938, was found deceased by neighbors behind the home with a dog leash tied to her waist. She had been outside for up 24-36 hours.
Her son, in his 50s, was found inside the home deceased.
The sheriff's office was called and they began to investigate due to the leash being tied to the woman's waist.
It was later learned one theory could be that she used the leash to help herself pull up if she was on her knees working in the garden and also clipped it to the dog and her waist while she walking it.
The leash was attached to the woman's waist and a car door when she was found outside.
Up to 15 investigators were involved in the case according to Caid.
According to Missouri Highway Patrol Sgt. Clark Parrott, the Division of Drug and Crime Control investigators are also assisting the sheriff's office and the East Prairie Police Department.
