Jeffery Trevino's attorney Friday filed a motion to ask for a delay of his client's murder trial next month, the Pioneer Press reports.
Trevino, who is accused of murdering his wife, Kira Steger, is due to stand trial on second degree murder charges July 22.
Officials in April originally scheduled a May 28 trial date.
In his motion Friday, Trevino's attorney, John Conard, said the defense needed more time to investigate issues raised by the final autopsy report.
Conrad also has raised issues regarding Steger's cell phone records obtained from police reports.
He said in the motion that Steger's phone was "powered on, and functional, giving a GPS signal somewhere in Brooklyn Center" on March 22.
According to the Pioneer Press, however, Steger's account was not active at the time -- and that the prosecution notified Conrad the phone had been sold and the person was identified.
Conrad also noted in the motion that a VOXER type of multimedia message was sent from Steger's phone "and received by a credible witness on Feb. 25," which was three days after Steger's car was found abandoned at the Mall of America in Bloomington.
