Police in Johns Creek - about 25 miles northeast of downtown Atlanta - found the family of four dead Monday morning.
Investigators at the Fulton County Medical examiner's office say Gurtej Singh Grover, 5, and Sartaj Singh Grover, 12, died of sharp force wounds to their necks, and their mother, Damanjit Kaur Grover, 47, died of blunt force trauma to her head. Police Chief Ed Densmore said Shivinder Singh Grover, 52, hanged himself.
Members of metro Atlanta's Sikh community turned to prayer - and each other - as they mourned the loss of the family. Word of their deaths began spreading by phone Monday afternoon, but there were more tears than answers.
"Everybody was crying on the phone, so we thought it would be best to meet together to pray," said Parvinder Singh, a member of Gurudwara Sahib in nearby Roswell.
More than 50 people gathered at the congregation Monday night to pray and console each other.
"There's a lot of anxiety going on, a lot of emotions flowing in," Singh said.
"It's very hard to imagine anything like this with such a great, loving family," Parvinder Singh said. "They were active members here. We used to see them practically every Friday and Sunday, except the last weekend we didn't see them."
The family had moved to the Atlanta area from Michigan, Parvinder Singh said.
Shivinder Grover, who had studied at the University of Michigan, was an executive at one of the many technology firms in Atlanta's northern suburbs, Singh said.
"He's an extremely talented and high-intellect guy," he said.
His wife had worked for Emory Healthcare in the past, Singh said.
A co-worker of the slain woman had called police and requested a welfare check when she didn't show up for work, Johns Creek city spokeswoman Rosemary Taylor said. Police responded to the gated apartment community around 11:30 a.m. Monday and found the bodies.
Funeral arrangements had not been set Tuesday. A family member from India was planning to travel to Atlanta to help with those arrangements, Singh said.
The deaths come six months after members of the tight-knit community met at Centennial Olympic Park in downtown Atlanta to mourn after the August mass shooting at a Sikh congregation in the Milwaukee suburb of Oak Creek, Wis.
This week's deaths are the first slayings to occur in Johns Creek since the city was incorporated in 2006, Taylor said.
