Olathe ? A former Kansas woman now living in Ohio has been charged in the murder of her husband, beaten to death in his bed more than 21 years ago.

Melinda Raisch, 46, remarried and the mother of three children with her present husband, was arrested Wednesday afternoon in Ohio’s Delaware County on a first-degree murder warrant issued in Johnson County. She is accused of plotting with another man to kill her husband, David J. Harmon, on Feb. 28, 1982. The other man, not charged in the case, was named as a co-conspirator in the documents filed Wednesday in Johnson County District Court.

Raisch lives in Delaware, a small community north of Columbus. The Johnson County judge who signed the warrant for her arrest set a $250,000 bond.

A man who answered the phone at Raisch’s house Wednesday night said he had no comment.

The alleged co-conspirator lives in another state, and two Johnson County lawyers who represent him said they had not seen the charges and declined comment.

In news accounts at the time of the killing, Melinda Harmon told police that two men broke into the couple’s duplex in Olathe and demanded keys to the bank where her husband worked.

According to her original statement, one of the intruders struck her and knocked her unconscious. She said that when she came to about 80 minutes later, she found her husband’s body in bed, and ran to a neighbor’s house to call for help.

David Harmon, who was 25, had multiple “massive blunt injuries” to his head and face, the autopsy report said.

The complaint alleges that Melinda Raisch knowingly lied to investigators “in an effort to avoid detection of her and her co-conspirator in the murder of David Harmon.” It said the two took steps to make it appear that the crime was a break-in.

A blanket covering the body was rearranged, a drawer in the bedroom was pulled out and a lid was removed from a jar containing keys “to make it appear as though a residential robbery had occurred,” the complaint said.

Prosecutors say the other man disposed of the murder weapon, which never was recovered.

Olathe Police Lt. Clark Morrow, the investigation division commander, praised the detectives and prosecutors who refused to let go of the case.

“David Harmon’s homicide was never forgotten by the Olathe Police Department,” he said.
