Defense expert: Murder suspect's girlfriend wrong


Kanfer testified during cross-examination that he is paid $4,000 a day to testify.

He also discussed his involvement in another controversial New Hampshire case — the 2003 death of Patric McCarthy in Lincoln. The New Hampshire medical examiner determined that McCarthy died of hypothermia after getting lost in the woods. His family maintains he was killed and hired Kanfer and other experts to review the autopsy report. Kanfer said the boy was smothered.

In 2011, the U.S. attorney and the attorney general closed out their investigations, concluding McCarthy died of hypothermia.

McDonough testified for 10 days. She told jurors she lured Marriott to the Dover apartment she shared with Mazzaglia because he wanted other women in their sex life. She said the three of them played a game of strip poker, and then Mazzaglia suggested Marriott and McDonough kiss. She testified Marriott rejected that notion and another that Marriott watch while he had sex with McDonough.

It was while she and Marriott were watching a movie, McDonough testified, that Mazzaglia came up behind them, slipped a rope around Marriott’s neck and pulled it until she lost consciousness. The pair then used Marriott’s car to transport her body to Peirce Island in Portsmouth and throw it into a river that feeds into the ocean. It has not been found.

McDonough is serving a 1½- to 3-year sentence for hindering the prosecution, conspiracy and witness tampering.

Testimony resumes today.
