Two people found dead in a Norcross home this week were a brother and sister involved in a murder-suicide, according to police.
The bodies of 45-year-old Hoang Nguyen and 49-year-old Glenda Nguyen were discovered after a landscaper, who had come to the cut the grass at the rental on N. Norcross-Tucker Road, noticed a foul odor coming from inside.
He flagged down an officer who forced entry into the house and discovered Glenda Nguyen in the living room.
"Investigators believe the male stabbed the female twice, once in the back and once in the abdomen, before taking his own life," says Capt. Bill Grogan.
He tells WSB's Sandra Parrish the medical examiner was not able to determine how Hoang Nguyen died. His body was located in a rear bathroom in the home.
The two only began renting the house a few months ago.
Grogan says the crime likely occurred around June 4, the last time anyone had contact with the pair.
He says Glenda Nguyen worked at a nail salon, but no one tried to locate her when she failed to show at work assuming she had gone back to Vietnam.
At this point the motive behind the murder-suicide remains a mystery. Grogan is asking anyone who knew the pair to come forward.
"If we could somehow put together a timeline of at least their last several months of where they've been and what they've been doing, that may help us determine what caused this incident to occur," he says.
Grogan is also looking for anyone who may be able to help locate family members of the siblings in Vietnam.
