The Vietnamese man and woman who were found stabbed to death at a hotel on the Las Vegas Strip have been identified as the director and employee of a Ho Chi Minh City-based travel agency.

The woman was Nghia Boi Sang, 39, director of Trieu Hao Tourist Company, and the man was Nguyen Le Ba Khuong, 30, one of her employees, according to the Embassy of Vietnam in the United States.

They were found dead with multiple stab wounds to their bodies inside a room at the Circus Circus hotel and casino.

The Vietnamese embassy has contacted the police unit in Las Vegas and family members of the two victims for further investigation and clarification.

The embassy has also reached Sang’s sister, who currently lives in the U.S., to assist the probe.

Meanwhile, the Ho Chi Minh City Department of Foreign Affairs will assist family members with their visa process so that they can arrive in Las Vegas in the earliest time.

Initial information showed that the incident happened at around 2:00 am on Friday (local time).

Sang and Khuong were leading a group of Vietnamese tourists on a trip to the U.S. organized by Trieu Hao Company.

They previously visited Los Angeles before arriving in Las Vegas for a two-night stay. The group was scheduled to get back to Los Angeles on Saturday before returning to Vietnam.

Their itinerary on Friday included a trip to the Grand Canyon.

After the Vietnamese tourists reported the absence of Sang and Khuong, employees of the hotel checked their room and discovered the bodies at around 3:00 pm.

"We're early on in the investigation and at this time we have not been able to determine if it's a murder-suicide or if it's a double homicide investigation," ABC7News quoted Las Vegas Metropolitan Police Department Lt. Ray Spencer as saying.

Police are "leaning" toward the incident being a murder-suicide, but this is something they will not know for sure until the coroner's examination, Spencer added.

Witnesses also recalled hearing a disturbance that sounded like an argument near the area around 2:00 am but no one reported the incident.

Security camera footage showed that the two victims went inside their hotel room on Thursday night and no one has entered or exited the room since then.
