OAK CREEK, Wis. — One by one, six coffins were rolled into a high school gymnasium here Friday and were surrounded by Sikh men and women singing traditional Punjabi hymns. As they sang, thousands of people from around the world streamed into the gym to mourn the six worshipers who were shot and killed on Sunday at the Sikh Temple of Wisconsin here.

The deaths have rocked the town and reverberated throughout the global Sikh community, leading neighbors to skip work and visitors from as far as India to converge at Oak Creek High School for a group memorial service and wake.

“These bullets have hit their hearts,” said Rajwant Singh, chairman of Sikh Council on Religion and Education, who traveled from Washington. “It has become a big family gathering. It is really a shaking moment hitting the core of the community.”

During the visitation, families of the victims stood next to the bodies of their loved ones. Wooden coffins, draped with white cloth, were lined up under the basketball nets. Behind each coffin was a portrait of the victim and flowers.
