DEDHAM, Mass. – A state police detective said Tuesday that a dominatrix told investigators she spent two hours trying to decide what to do with the body of a client who authorities believe died of a heart attack during a bondage session.

Barbara Asher, who is on trial for manslaughter in the death of Michael Lord, told police that she and her boyfriend settled on a plan to chop up the body and dump it because it was too big to carry out of Asher’s condominium, said the detective, Sgt. Dermot Moriarty. Lord’s remains were allegedly dumped in Maine.

Defense lawyers claim there never was a confession and that there’s no physical evidence that Lord was ever in Asher’s Quincy home.

Lord, 53, of North Hampton, N.H., disappeared in 2000, and his body has not been found.

Moriarty said Asher told detectives that she and her boyfriend worried that they wouldn’t be able to carry the body out of Asher’s fourth-floor condominium. He weighed about 275 pounds and stood 6-foot-4.

Police recorded most of the two-hour interrogation, during which Asher denied having seen Lord on July 3, 2000, the day authorities believe he died. Asher at one point asked that the recorder be turned off, then she allegedly confessed.

Moriarty said he took notes from the interrogation’s untaped portion, but discarded them.

“After I created my police report, I just threw out the notes,” Moriarty said.

He said his report did not include a verbatim account of Asher’s statements, and none of the detectives asked her to restate her confession so it could be recorded.

Asher, 56, is accused of failing to call paramedics because she was worried her dominatrix business would be discovered.

Prosecutors say Asher and her boyfriend dismembered the body in a bathtub and disposed of it in trash bags behind a restaurant in Augusta, Maine.
