Tonight... Get on the record with Greta!

A public memorial service in Minnesota will honor the memory of Senator Paul Wellstone, his wife, daughter and three campaign aides who were tragically killed in a plane crash on Friday.

We'll have a live report from our FOX News correspondent Steve Brown and we'll also be joined by New Jersey Democrat Senator Jon Corzine who will share his memories of Senator Wellstone with us.

Then, we'll turn our attention to the aftermath of the Beltway sniper case. Could the crime that John Allen Muhammad and John Lee Malvo engaged in have been much more extensive than law enforcement first realized? We'll have new information for you. Plus, as more states come forward with crimes they would like to see prosecuted, how will this case unfold? And who will defend the two suspects? We'll hear from two legal eagles and get their views on this very complicated case.

Be sure to watch tonight's edition of On the Record with Greta Van Susteren at 10 p.m. ET only on the FOX News Channel.
