The Utah doctor accused of killing his ex-wife is scheduled to appear in court on Monday, KUTV reported.
Prosecutors claim John Brickman Wall, 49, murdered Uta Von Schwedler in 2011. He was arraigned last November and pleaded not guilty.
Fred Metos, an attorney for Wall, is asking the judge to throw out a series of statements that Wall made to police after Von Schwdler's body was found.
During an evidentiary hearing last fall, a detective testified that Wall was unable to say where he was the night of his ex-wife's death or when he had last seen here. Those statements, along with other examples of strange behavior, led prosecutors to charge Wall with Von Schwedler's murder 18 months after her body was discovered.
In court documents, Metos argues the statements should not be allowed during trial because he made them under "psychological and physical coercion." The judge in the case will likely made a decision after the hearing on Monday.
Wall was interviewed by police hours after Von Schwedler's boyfriend found her in her bathtub on Sept. 27, 2011. According to court documents, Wall's interrogation lasted from 11:30 p.m. to 4 a.m. The discussion between Wall and police "grew very heated" and included Wall telling them that he was diagnosed with depression and began self-medicating with Lexapro and Trazodone.
Still, prosecutors claimed in a response motion that the statements should remain at trial.
"The statements of the defendant were voluntarily made and are not a product of physical or psychological coercion," Deputy Salt Lake District Attorney Matthew Janzen wrote.
Another motion will be argued in court on Monday, with prosecutors claiming one of Wall's attorneys, Howard Lundgren, should be removed from the case. Prosecutors want to call Lundgren, who worked as a divorce attorney during Wall and Von Schwedler's divorce, as a witness in the trial.
