Family: Victim Fought Gunman in Lobby of Sikh Temple
OAK CREEK, Wisconsin -- Several years ago, Satwant Singh Kaleka put a large American flag in the front of his yard, raising the eyebrows of his children, who thought it might be considered an eyesore.

Kaleka pointed out there were no homes nearby with flags, and he wanted to show that the United States was a land of opportunity, said his son, Amardeep Kaleka.

The elder Kaleka, 65, served as president of the Sikh temple in Oak Creek, Milwaukee, scene of Sunday morning's mass shooting. He was one of six community members killed.

"He lived the American dream," Amardeep Kaleka told CNN's "AC360" on Monday night.

His father brought his family to the United States with little money but a strong work ethic in the early 1980s.

The flag also was a form of protection for the family, Satwant Kaleka told them.

It stood at half-staff Monday evening as the family grieved.

The six killed in Sunday's attack were identified by police as five men -- Kaleka; Sita Singh, 41; Ranjit Singh, 49; Prakash Singh, 39, and Suveg Singh, 84 -- and a woman, 41-year-old Paramjit Kaur.

Amardeep Kaleka told Anderson Cooper people called to tell him that his father saved many lives Sunday.

Earlier Monday, the son said he was not surprised his father tried to stop the gunman at a Sikh temple in Wisconsin.

"It's an amazing act of heroism, but it's also exactly who he was," Amardeep Kaleka told CNN Milwaukee affiliate WTMJ. "There was no way in God's green Earth that he would allow somebody to come in and do that without trying his best to stop it."

Amardeep Kaleka told CNN that the FBI told him his father attacked the shooter in the lobby, resulting in a "blood struggle."

A knife close to the victim's body showed blood on it, he said.

"From what we understand, he basically fought to the very end and suffered gunshot wounds while trying to take down the gunman," said Kanwardeep Singh Kaleka, Satwant's nephew.

Satwant Kaleka's wife, Satpal, hid with several other women, telling them to remain quiet during the horrific incident.

The gunman came into the kitchen and shot and wounded two women, she told CNN. "I grabbed everybody and said run, run to the pantry."

Amardeep Kaleka said his father worked hard and was an honest man.

"I would love for them (the public) to know that he lived his life with the principles that he knew and he was taught at a young age. It made him highly successful in America."

Another victim, Suveg Singh, spent every day at the temple, said his granddaughter, Sandeep Khattra.
