"(The team) out of the Memphis crime lab responded to the Swift residence today to look for evidence of a crime scene," said TBI spokesperson Kristin Helm. "The Special Agent Forensic Scientists are specially trained to look for trace evidence that could be collected and processed back at the laboratory."
Dyer County Sheriff's Chief Investigator Terry McCreight said the family is cooperating with them and voluntarily left the house while agents performed their investigation. Deputies initially searched the house on Sunday after Swift was reported missing.
Although the forensic agents were mainly focused on the residence and collecting evidence, McCreight said nothing specifically led them there other than that is where she was last seen.
"We just want to make sure we are following the necessary steps in this investigation," said McCreight.
As investigators gathered outside the residence Thursday afternoon, District Attorney General Phil Bivens and TBI Agent John Maher spoke briefly with them.
Dyer County Sheriff Jeff Box and a Shelby County Sheriff's investigator also searched areas of interest and processed potential evidence.
"We are still piecing information together in this case," said Box.
Karen Johnson Swift is described as:
Height: 5' 5"
Weight 138 lbs.
Anyone who has had contact with Swift, recalls seeing anyone near her vehicle since her disappearance, or has information regarding her whereabouts is asked to contact the Dyer County Sheriff's Office at 731-285-2802.
