A man and woman were found fatally stabbed inside of a room at the Circus Circus casino in Las Vegas this week.

According to Fox News, the bodies were discovered on Friday when hotel security staff was called to conduct a welfare check on the room’s occupants.

Police did not provide the victims’ names in a preliminary statement to the media.

Officials did confirm that the man and woman were visiting Nevada from their native Vietnam. They were part of a larger tour group and had planned to visit the Grand Canyon later Friday after arriving in Las Vegas the previous day.

It was other members of that group, police say, who initially reported the victims’ absence to hotel staff after they failed to show up for a scheduled excursion.

According to Las Vegas Police Lt. Ray Spencer, both victims sustained multiple stab wounds.

He said police were investigating reports from neighboring guests who reported hearing an argument in the room early on the morning of the stabbing.

While others from the tour group were questioned by police, reports indicate that initial efforts were hindered by a language barrier.

As of early updates in the case, there was no identified suspect and no one had been arrested in connection with the double homicide. Police said there was no active threat to the safety of guests at the hotel.

In a statement, the casino’s owner, MGM Resorts International, confirmed that it would be cooperating with authorities as the investigation moves forward.
