The Kansas Supreme Court has scheduled an April 25 hearing in the appeal of Martin K. Miller, a Lawrence man sentenced to life in prison in 2005 for the murder of his wife.

Miller, a carpenter and former Christian-school teacher, was convicted of first-degree murder in the strangulation of Mary Miller, who had been a Kansas University librarian.

Martin Miller has denied he killed his wife.

Miller has appealed his conviction saying trial jurors were unfairly prejudiced against him because of evidence presented about his sexual behavior.

Prosecutors had presented evidence of Miller pursuing sexual relationships with other women and pornographic photos found on his computer.

Under Miller’s sentence, he must serve 25 years before being eligible for parole.
