The victim — who hasn’t been identified — plummetted 18 stories around 1 a.m. Thursday at the Hyatt Regency in downtown Dallas, news station WBAP reported.

Authorities cordoned off the area and covered the ground with a tarp while they investigated, according to the Dallas News.

Hotel staff reportedly requested guests not take photos of the scene.

It’s unclear whether the fall was accidental.
