Police have started probing the murder angle after authorities found the body of the missing Tennessee women, Karen Johnson Swift, near a highway.

She had been there some time. The body had been concealed by vegetation, Dyer County Sheriff Jeff Box told ABC News's Western Tennessee affiliate WBBJ-TV.

The remains of Swift's body were found in bushes near a private cemetery by a passerby and there were no signs that she was killed in some other location, the sheriff said.

The place where the 44-year-old's body was found is just three miles away from where Swift's abandoned car, a white 2004 Nissan Murano, had been found with a flat tire.

Box said that the things they had got while searching the car could serve as a key to the investigation, but would not elaborate on what the items were.

Swift, mother of four, was last seen by her husband at her home in Dyersburg at around 1:30 a.m. Oct. 30.

There were some apparent injuries to the body, Box told WBBJ. We're going to wait to let the medical examiner's final report tell us the extent of those injuries.

According to Box, it could be two weeks before a Memphis coroner releases the final autopsy report.

At this time we haven't named any suspects and you won't see us name suspects until we're sure it's going to be beneficial to the investigation, Box said.

Swift had filed for divorce from her husband twenty days before she had gone missing, citing irreconcilable differences.

Swift had four children - two boys and two girls. Her two sons are in college and her daughters are seven and nine years old.

Swift's body was found Saturday after the once-green vegetation thinned due to the cold weather and her body was later identified, using dental records.
