From the Boston Globe article posted above:
"On Monday, lawyers for the Globe and other news organizations asked Lauranzano to unseal the affidavit and other records, a move opposed by Blodgetts office and a lawyer for Ritzers family, who told the judge her family was still grieving the loss of the popular 24-year-old teacher.
Michael J. Grygiel an Albany, N.Y., lawyer represented the Associated Press, GateHouse Media, and the Eagle Tribune Publishing Co. in court.
Lauranzano, in his decision, extended the sealing of the affidavit to Nov. 22, the date that prosecutors have said they would finish presenting evidence to the grand jury."
Personally I think the still grieving family argument is a little lame. I am pretty sure they will be grieving for a very very long time. And, it could lead to speculation that there is something particularly unusual in this case.
