"We are confident we will bring the person, or persons responsible, to justice," said Box. "The investigation is still active and ongoing."
As the investigation enters its 156th day, Box said he would not release any details about the investigation due to the fact it would jeopardize the investigation.
"Our office has collected much evidence in the case and investigators still are confident that an arrest will be made when the investigation is complete, but not until then," stated Box. "We will protect the integrity of this case up to the arrest and maintain this integrity during the trial to see that a conviction is received. This case must and will be tried in a court of law and not in the media, not on the Internet, and not in the newspaper."
Swift, a 44-year-old mother of four was reportedly last seen early Sunday morning, Oct. 30, 2011, by her husband David Swift at their home on Willie Johnson Road. She had filed for divorce from David Swift, on Oct. 10, 2011, but still resided with him and their two daughters at their residence. Her white 2004 Nissan Murano was reportedly found abandoned several hours on Sunday, Oct. 30, 2011, on Millsfield Highway near the intersection of Harness Road with a flat tire. An investigation into her disappearance continued until Saturday, Dec. 10, 2011, when her body was found by a cemetery caretaker near Bledsoe Cemetery in Dyer County, which is just off of Harness Road. After the body was positively identified as Karen Swift, Box stated the case was being investigated as a murder. An autopsy was performed on Swift's body by the Shelby County Medical Examiner's Office in Memphis and she was buried in Pocahontas, Ark on Feb. 11.
The Dyer County Sheriff's Department is still asking anyone who had contact with Swift before her disappearance, recalls seeing anyone near her vehicle on Millsfield Highway on Oct. 30, 2011, or has any other information about the case to contact the Dyer County Sheriff's Office at 731-285-2802 or 1-800-TBI-FIND.
