The Washington County Sheriff's Department says the case of the death of a 90-year-old woman is closed.
Ida Kale's death two years ago at the home in Lowell was originally ruled to be from natural causes, but late last year, a further investigation was requested after traces of a muscle relaxant were found in Kehl's body.
It's now been determined that no foul play was involved, and that the chemical actually formed in her body after her death.
“At death, a small amount of that drug is in the liver. And when the body is embalmed, it flushes the drug to several other organs. That's why, when several organs are tested, it comes back as positive with the drug in the body,” says Det. Jeff Seevers.
The final ruling on Kehl's death was made after tests were conducted by an FBI lab at the request of the sheriff's department.
