NEW CITY - A second suspect involved in the murder of Rockland County political activist Peggy Nadell has pleaded guilty.

Eltia Grant pleaded guilty to a hindering prosecution charge this afternoon and agreed to cooperate against two other women charged with murdering the 80-year-old grandmother.

Co-defendant Tanisha Joyner has already agreed to a similar plea deal, strengthening the case against both Diana Nadell, Peggy Nadell's daughter-in-law, and Andrea Benson.

Nadell and Benson are believed to have conspired to kill Nadell for her $4 million estate.
