Sita Singh moved to New Delhi after completing his education. Prior to moving to the United States in 1995, he lived in Canada and England. He moved to the Sikh Temple only six months before the shooting.
Sita Singh is survived by his wife, Surinder Kaur, and four children, Sarabjeet Kaur, Harmeet Singh, Kamaljeet Kaur, and Jasbir Singh. He was a very dedicated Sikh, who selflessly attended to all duties at the temple, including daily services, maintenance, and cooking. He was also very fond of music and reading.
