Investigators looking into the disappearance of Kira Steger Trevino have obtained search warrants that will give them access to hers and her husband's Facebook accounts to search for evidence in her disappearance, the St. Paul (Minn.) Pioneer Press reported.
Trevino, 30, was last seen in public Feb. 21 and was reported missing by her husband, Jeffery Trevino, Feb. 24.
Jeffery Trevino, 39, was arrested Feb. 26 and has remained at the Ramsey County Jail in lieu of $1 million bail. He is accused of killing his wife, although her remains have not yet been found.
The search warrant affidavit made public Wednesday said a friend of Jeffery Trevino told police that before Trevino was arrested, he made a Facebook post that included the initials "NWNP," which may mean "No Witnesses No Proof."
Police also obtained a search warrant for the Facebook accounts of Kira Steger Trevino and Matthew Roff, who lived with the couple.
When asked why police were seeking Roff's Facebook records a police spokesman said, "We're doing a thorough investigation and we're going to go in whatever direction any investigation may lead. We are covering all bases."
Defense attorney John Conard said he had not seen the search warrants.
