Gov. Scott Walker released a statement on the incident Sunday, saying that state officials are working with the FBI and local law enforcement and are continuing to receive updated briefings about the situation.

"Our hearts go out to the victims and their families, as we all struggle to comprehend the evil that begets this terrible violence," Walker said in the statement. "At the same time, we are filled with gratitude for our first responders, who show bravery and selflessness as they put aside their own safety to protect our neighbors and friends. Tonette and I ask everyone to join us in praying for the victims and their families, praying for the safety of our law enforcement and first responder professionals, and praying for strength and healing for this entire community and our state." 

President Barack Obama said he and first lady Michelle Obama are "deeply saddened" by the killing of at least six people Sunday at a Sikh temple in Wisconsin.

In a statement issued by the White House, Obama told the people of Oak Creek that "the American people have them in our thoughts and prayers." He said, "Our hearts go out to the families and friends of those who were killed and wounded."

The president said his administration will provide "whatever support is necessary" to those investigating the shooting.

Obama stressed "how much our country has been enriched by Sikhs," whom he described as "part of our broader American family."

By sundown, prayer returned, but in the form of a vigil at a downtown Milwaukee park.

"It's all human beings," said Shashi Bhushan, who came to the gathering. "It doesn't matter what religion, what community, we're just here to show support."

Those at the vigil held hope in their hands with a flicker of light that they hoped could bring peace back.

One unidentified attendee vocalized what many were thinking.

"I think we need some awareness in people that we need to respect other people's religion and be considerate and be loving."

Police gave no answers as to the shooter's motive, but Sikh members say they are often confused for Muslims due to their turbans and long beards.

Many wondered if, in the post-9/11 world, Sunday's shooting wasn't a result of that confusion.
