A body found in wooded area identified as missing Tenn. mom of four, Karen Swift

(CBS/WREG/AP) MEMPHIS, Tenn. - A body found Saturday in a wooded area in Dyer County has been identified as Karen Swift, the missing Tennessee mother of four.

CBS affiliate WREG reports that the Tennessee Bureau of Investigation confirmed the identity of the body Monday morning. Swift, 44, had been missing for nearly a month and a half.

The TBI believes that Swift was murdered, but has not released any information pertaining to how she died. The homicide investigation is ongoing, reports TBI special Agent in Charge Mehr. "Leads are coming in every day and investigators will be following up on all information. We'll be looking in all directions."

Swift had been missing since late October. After her disappearance was reported, her car was found with a flat tire.

Swift's body was found badly decomposed and covered in vegetation. Investigators used many techniques to identify the body, which was found about three to four miles from where her SUV was discovered.

Investigators had searched the area in which she was found before, but because of difficult terrain and heavy growth in the area, the body may have been difficult to see.

"There were some apparent injuries to the body," Dyer County Sheriff Jeff Box said. "We're going to wait to let the medical examiner's final report tell us the extent of those injuries."

"I think it was placed there," Box said of her body. Investigators are waiting on DNA samples from evidence found in Swift's car, home, and on her body.

Box told ABC News that the items recovered from her car could be key to the investigation but would not say what the items were.

Box said he's confident investigators will catch Karen Swift's killer.

Swift's estranged husband, David, who had recently filed for divorce, has cooperated in the case, Box said.

"That includes DNA samples, he's come in and was interviewed," Box said. "He allowed us to interview one of the children. So far he's submitted to every request for search of anything on that property."
