The Fulton County Medical Examiner’s office on Tuesday identified the four family members found dead in their John’s Creek apartment.

The four were identified as Sindiver Grover, 52, his wife, Damanjit Kaur-Grover, 47, and their sons, 12-year-old Sartaj Grover and Gurtej Grover, 5.

The Fulton County Medical Examiner’s Office said autopsies showed the two children died of sharp force injuries to the neck. Such injuries are defined as stab wounds, incised wounds and chop wounds.

Damanjit died of blunt force head injuries.

Sindiver died of ligature hanging and was ruled a suicide.

A press conference is scheduled for 3 p.m.

There had been nothing to indicate trouble in the spacious Johns Creek apartment where the four bodies were found.

Neighbors say the Grovers were a happy couple. Police said their visit to the gated Aylesbury Farms apartment a little before noon Monday was the first time they’d been called there.

Answers may be hard to come by, as Johns Creek Police Chief Ed Densmore said.

“It’s a rather complicated crime scene right now,” Densmore said at a late afternoon news conference. “We’re going to be here for hours.”

Those who knew the family were shocked to hear what had happened.

“The father comes out nearly every morning and puts the kids on the school bus,” said one neighbor who lives in an adjoining complex. She said she routinely saw the boys playing outside.

Joseph Olander, who lives above the victims, called the Grovers “a very loving couple.” He reported hearing nothing unusual Monday morning.

Officers were dispatched after a welfare check was requested by a co-worker of one of the adult victims, Densmore said.

Densmore would not speculate on which member of the family apparently did the killing.

“It’s pretty bad as you can imagine,” the police chief said. “Any time you deal with something this bad involving kids, it’s heart-wrenching.”

Relatives of the deceased began arriving at the complex around 3 p.m. About that same time, children were returning home from school.

A group of 15 children, some whom lived inside the area cordoned off by police, gathered near the scene of the deaths. Police escorted them to their homes, telling them a tragedy had occurred while assuring them they were safe.

“This is the first time we’ve seen anything like this,” said neighbor Benjamin Rad. “You’re shocked when it happens right next to where you live.”

The homicides were the first in the history of Johns Creek, which was incorporated in December 2006.
