MGM resorts has sold off the Las Vegas site of the deadliest mass shooting in US history.

The 15-acre (6.1 ha) Village property was purchased by the Three Affiliated Tribes of the Fort Berthold Indian Reservation based in central North Dakota.

CEO and President Bill Hornbuckle disclosed the news to his staff in a letter on Friday.

Concertgoers at the Route 91 Harvest Festival gathered there on October 1, 2017, when a gunman opened fire from his hotel room above, killing 58 people. Two more died later of their injuries. More than 850 people were hurt by the time the gunfire stopped.

The site has remained unused and largely unchanged since the shooting.

What the tribes have in store for the plot has not been revealed, but widespread speculation says they will likely open a casino, possibly after demolishing the existing buildings.

Planned memorial

Last August, MGM Resorts donated two acres on the northeast corner of the property for the permanent memorial after a survey conducted by Clark County found that a majority of respondents wanted the tribute built at the site of the shooting.

Planning for the memorial has been underway since late 2019, but it could be years before the final tribute is unveiled. The sale does not include the two acres.

Hornbuckle says he knows the location means a great deal to many. But the Tribes “have demonstrated that they care about our community, its future and, of course, its past,” he wrote.

The Three Affiliated Tribes is made up of the Mandan, Hidatsa and Arikara Nation. They are also known as the MHA Nation.

Representatives for the Tribes did not immediately return a message from The Associated Press seeking comment.
