Matthew Nilo stands during an appearance at Suffolk Superior Court, Thursday, July 13, 2023, in Boston. Nilo, a New Jersey lawyer already charged in connection with a series of sexual assaults in Boston's Charlestown neighborhood about 15 years ago, pleaded not guilty on Thursday to new charges stemming from a different series of sexual assaults in another area of the city that occurred at roughly the same time.

Prosecutors say they are still making their way through more than 45,000 communications between Boston Police investigators about the investigation into Matthew Nilo, a New Jersey lawyer accused of assaulting eight women in Boston more than a decade ago. 

In a brief court filing asking to continue a hearing in Nilo’s case, Assistant District Attorney Lynn Feigenbaum said the 45,000 communications received by prosecutors since Nilo’s last court date total 500,000 pages. So far, they have turned over 1,200 documents to attorneys for Nilo, totaling 9,000 pages.
