(WMC-TV) - Authorities in Dyer County aren't leaving any stone unturned in their continued search for Karen Swift. Wednesday, officers combed this wooded area near Swift's home in search of clues.
"Were looking for any unknown tracks," Dyer County Sheriff Jeff Box said. "Any unknown items in the area that might possibly have been left behind by her or someone else, if someone else is involved."
Swift was last seen at her home early Sunday morning. Friends say the mother of four children had just returned from a Halloween party.
Investigators say Swift's husband, who she is divorcing, spoke to her at home, and then went to bed.
Investigators later found Swift's vehicle, a white 2004 Nissan Murano, with a flat tire in Northern Dyer County on the Millsfield Highway near the Harness Road intersection. She was gone.
"We transported the vehicle yesterday to the Tennessee Bureau of Investigations crime lab, where the technicians will process it in their facility, and hopefully they'll be able to answer some of the unanswered questions for us," Box said.
Investigators are tracking every lead as they try to determine how Swift may have vanished.
"Other than the amount if time she's been missing, that concerns us," Box said."We don't have any evidence to state there is foul play."
While the search for Swift remained in full swing, her brother, Jeff Johnson, was trying to come to grips with her disappearance.
"It's been devastating," he said. "It still is. I'm in total shock. I keep hoping for the best."
Johnson says he and his family are helping investigators as they track leads to try to determine how Swift may have vanished.
"It's taken a pretty good toal on our family right now," he said. "Everybody is trying to hold themselves together. We just pray for her safe return really."
