The home of a woman who went missing almost three weeks ago was raided by police Wednesday afternoon in Portage.

MLive reports that authorities have not said what they were searching for, or what they found at the home of Theresa and Christopher Lockhart Wednesday. The search warrant was executed with an effort involving the Portage Department of Public Safety, Michigan State Police and Kalamazoo SWAT team; Christopher Lockhart, who has been named as a person of interest in his wife’s disappearance, was home when police arrived and was seen leaving the home in an unmarked car, but he was not arrested.

Theresa Lockhart was last seen the night of May 18 leaving her home, and was reported missing two days later not by her husband, but by the Schoolcraft School District, where she works as a Spanish teacher. Christopher reportedly has been uncooperative with investigators since her disappearance.
