Thousands of mourners are expected to pay their final respects to the half-dozen Sikh (seek) worshippers gunned down by a white supremacist at their Wisconsin temple over the weekend.
Organizers initially allocated two hours for a wake and visitation. But they added two hours to accommodate demand.
Dignitaries scheduled to attend include U.S. Attorney General Eric Holder, Wisconsin Gov. Scott Walker and U.S. Rep. Paul Ryan.
The service will include prayers and hymns. Afterward mourners plan to return to the temple and begin a traditional 48-hour ceremony intended to honor the memories of the victims.
Forty-year-old Wade Michael Page opened fire Sunday at the Sikh Temple of Wisconsin. He killed six and wounded three others, including a police officer. He killed himself after a second officer wounded him.
