Olathe ? A woman found guilty earlier this year of beating her husband to death is expected to testify against another defendant in the 23-year-old killing.

Johnson County Dist. Atty. Paul Morrison requested a postponement of the sentencing of Melinda Raisch, convicted in May in the death of David Harmon.

Another person charged with Harmon’s beating, Mark S. Mangelsdorf, still faces trial in the case. Mangelsdorf testified in Raisch’s trial, and Morrison said she would now testify in Mangelsdorf’s trial.

“We expect to call her as a witness in the case,” Morrison said Thursday.

Raisch faces a mandatory life sentence with no chance of parole for 15 years on the murder conviction, based on Kansas law in effect in 1982. She also faces a maximum sentence of five to 20 years in prison for a conspiracy conviction.

Morrison would not say how Raisch’s testimony could affect her sentencing, but he told The Columbus Dispatch it would likely “cut down on her jail time.”

Prosecutors claimed Raisch and Mangelsdorf were romantically involved and conspired to kill Harmon because their church, the Nazarene Church, did not condone divorce.

Mangelsdorf testified he was a friend of the couple and denied any romantic relationship with Raisch.

After the killing, Raisch moved to Ohio, where her parents lived. She graduated from Ohio State University and remarried in 1986. She and her current husband have two children.
