PONTIAC, Mich. -

Officials have confirmed that the mummified remains of a woman found in the garage of a suburban Detroit home in March were those of the woman who lived there alone.

The Oakland County medical examiner's office confirmed to Local 4 that Pia Farrenkopf had been positively identified using DNA testing.

The cause and manner of death could not be determined because the body was mummified.

Investigators said in March that they believed the remains were Farrenkopf, a self-employed financial trouble-shooter who would have turned 50 this year.

Her body was found in the rear seat of her Jeep, inside the garage of her Pontiac home. Officials said she could have been dead for more than five years and that there was no evidence of foul play.

Oakland County authorities say Farrenkopf paid her mortgage and other bills automatically through a checking account that once had a balance of $54,000. The money ran out last year, and the Pontiac home went into foreclosure. A contractor sent by the lender discovered the body.

Farrenkopf, who was single, traveled the world and had family in Massachusetts.
