The pungent smell of Tennessee heiress Eliza Fletcher’s decaying corpse led a police search and rescue team to discover her body, documents obtained by The Post Tuesday revealed.

Fletcher, of Memphis, went missing Friday during her early-morning jog and was discovered by authorities on Monday after a multi-day search.

Police charged Cleotha Abston, 38, with her murder and kidnapping. In the affidavit released Tuesday, authorities outlined grisly new details about how they found Fletcher, 34, in high grass near a vacant home on Victor Street in south Memphis.

“The officers noticed vehicle tracks in the grass … and the officers smelled an odor of decay,” according to the affidavit. 

After following the smell, a cop “located an unresponsive female lying on the ground.”

Photos obtained by Fox News show the house and area where Fletcher’s body was found.

Authorities announced the discovery of a body that Monday, but didn’t confirm it was Fletcher’s until Tuesday. Her body was found more than three miles southwest of her home in the tony Central Gardens neighborhood.

“The scene investigation revealed that the female fit the description of missing person, Eliza Fletcher,” the doc said. 

After the discovery, law enforcement also found a trash bag that “contained purple Lululemon running shorts that were consisted [sic]  with the ones Eliza Fletcher was last seen wearing.”

Fletcher’s body was found in an area close to where police say Abston was seen cleaning out the GMC Terrain seen in surveillance footage of Fletcher’s violent abduction.

She was snatched off the street about five miles east of her home.

Abston, who previously served 20 years in prison for a violent kidnapping, refused to reveal where Fletcher was after his bust.

Fletcher was the mom of two young boys, an elementary school teacher and granddaughter of a billionaire hardware company magnate.
