Using DNA, authorities have identified the mummified remains that were found in a suburban Detroit garage in March as being former Massachusetts resident Pia Farrenkopf.

Farrenkopf’s body was discovered in the backseat of a car parked in her garage, according to The Detroit Free Press. She had been dead for about five years, and Oakland County Deputy Medical Examiner Dr. Bernardino Pacris told the Free Press that normal methods of determining a cause of death were not possible, but authorities said there is “no evidence of foul play.”

Farrenkopf’s body didn’t have organs such as the heart, liver and lungs that he could examine like he would normally do when determining how a person died. “The possibility of hypothermia or any drug or chemical intoxication cannot be ruled out,” Pacris told The Free Press.

A bank contractor found the body on March 5 after Farrenkopf’s house went into foreclosure, WCVB reports.

Oakland authorities said the self-employed financial trouble-shooter paid for her mortgage and other bills automatically through a checking account that ran dry about a year ago, according to WCVB.

WCVB reports that Farrenkopf was one of 10 siblings who grew up near Boston. Her family describes her as “intensely private” and said they last saw her in 2007.

Paula Logan, Farrenkopf’s sister, told WCVB that the family tried to get in touch with her sister over the years. “The phone just rang, rang, rang,” Logan said.
