DEDHAM, Mass. (AP) – A dominatrix charged with manslaughter in the death of her client described to police how she watched her boyfriend dismember the body, then helped him load the parts into trash bags for disposal, a police detective testified at trial on Thursday.

But defense lawyers claimed there never was a confession and that there is no physical evidence that the client was ever in the dominatrix’s apartment.

Barbara Asher, 56, is charged in the death of Michael Lord, 53, a New Hampshire man who has not been seen for more than five years.

Prosecutors say Asher, who is known as Mistress Lauren M, failed to call paramedics when Lord suffered a heart attack during a bondage session in her Quincy condominium on July 3, 2000.

Police played an audiotape in court on Thursday in which Asher denied multiple times that she saw Lord that day.

When police claimed they had surveillance video of Lord entering Asher’s apartment building, and that Lord wrote about her in his diary, she asked that the recorder be turned off.

“Ms. Asher got very upset and started crying and she told me that she had seen things that not even a coroner would see,” Salem, N.H., Detective Mark Sambataro said in Norfolk Superior Court.

Asher’s defense asked on cross-examination if there was any corroborating evidence that Lord had been to Asher’s apartment. No blood or DNA evidence was ever found.

“All I have is her statement to us,” Sambataro said.

“Give us something else, facts, evidence, objective detail, what,” defense lawyer Stephanie Page shot back.

“I don’t have anything else,” Sambataro replied.

Police say Lord, a retired telephone company worker from North Hampton, N.H., suffered a heart attack while strapped to a rack in her condominium, but said she did not call 911 because she was worried her business would be discovered.

Asher and her boyfriend allegedly dumped Lord’s body parts in Augusta, Maine, but no remains have ever been found.
