The Dyer County Sheriff's Office searched the home of David Swift Thursday evening.
Swift is the estranged husband of Karen Swift, who was found dead near her Dyersburg home in November 2011.
The sheriff's office confirmed to FOX13 News the fact that it was executing a search warrant at the home in Dyersburg, but wouldn't go into detail as to what they are looking for.
Sheriff Jeff Box said the search warrant was executed just after 6:15 p.m.
Ms. Swift disappeared after a 2011 Halloween party and her body was found days later at a cemetery only about two miles from her home.
She and her husband were reportedly estranged, even though they were living in the same house at the time of the murder.
Swift murder suspects narrowed to 1
