A group of Sept. 11 family members vowed Thursday to protest when the unidentified remains of World Trade Center victims are moved to a repository at the site this weekend. The relatives said that housing the remains beneath the National September 11 Memorial Museum site would be disrespectful and that they would rather see the remains entombed above ground. "Let us have a voice!" said retired firefighter Jim Riches, who lost his firefighter son in the 2001 terrorist attacks. Sally Regenhard, who also lost her firefighter son, said family members dread the opening of the museum May 21.
