OAK CREEK, Wis. — Thousands of mourners are expected to pay their final respects Friday to six worshippers gunned down by a white supremacist at a Sikh temple in suburban Milwaukee over the weekend.

Organizers initially allocated two hours for a wake and visitation at a nearby high school, but they extended that by two hours to accommodate mourners who traveled from abroad and U.S. Attorney General Eric Holder as a last-minute speaker. Other dignitaries expected to attend the funeral include Wisconsin Gov. Scott Walker and U.S. Rep. Paul Ryan.

The service will include prayers and hymns.
