A medical examiner has determined the cause of death of a 71-year-old woman who was allegedly killed by her grandson last week in Nashua, New Hampshire.
Cynthia Toupin was killed by sharp-force trauma to her neck, in what was a homicide, a deputy chief medical examiner told prosecutors, New Hampshire Attorney General John Formella and Nashua Police Chief Michael Carignan said in a statement Monday.

Also Monday, Toupin's grandson, Jacob Abraham, waived extradition to New Hampshire, prosecutors said. The 27-year-old was arrested in the killing in Lowell, Massachusetts, on Friday, a day after Toupin's death.
Prosecutors anticipate that Abraham will appear in court to face the charges against him -- second-degree murder -- on Tuesday. It wasn't immediately clear if Toupin had an attorney who could speak to the charge.
