Hall County deputies performing a wellness check at a Buford-area home shot and killed a man Tuesday before discovering the bodies of a mother and her daughter who lived there, authorities said.

Investigators consider the man, identified as 51-year-old Thang Duc Doan, as the only suspect in the deaths of the two women, 42-year-old Kim Nguyen and her daughter, 18-year-old Lam-Anh Tran, according to the Hall sheriff’s office. The GBI is investigating the shooting.

Deputies were sent to Nguyen’s home in the 3200 block of Long Creek Drive around noon to perform the check and investigate a possible missing person case but could not get anyone to come to the door, according to a GBI news release. A concerned relative of the women later went to the home and spoke with Doan, who said the women were not there.

The relative told deputies that Doan had what appeared to be blood on his clothes, and with that information, a search warrant for the home was secured, the release states.

By 11 p.m., deputies entered the home and encountered Doan holding a knife and making “aggressive movements” toward them, according to the sheriff’s office.

“As a result, the man was shot and killed by deputies,” a sheriff’s spokesperson said in a news release. “No deputies were injured.”

After securing the scene, deputies continued searching the home and found the bodies of the two women. The agency did not say how or when they were killed. Their deaths are being investigated by the sheriff’s office.

The GBI will conduct an independent investigation into the shooting, and upon completion, the case will be handed over to the Northeastern Judicial Circuit District Attorney for review.

The officer-involved shooting is the 74th investigated by the GBI this year.
