Patrick Johnson, 57, was found dead in Las Vegas on the evening of September 13, 2016.

He had plans to meet someone for dinner at about 8:00 PM that night, but the identity of that person and whether the dinner occurred are not known. There is a large gap between when he was last seen and when his body was found; investigators have not disclosed a clear timeline or any surveillance footage of his movements that evening.

Anyone with information about Patrick Johnson’s plans or whereabouts on September 13, 2016, is asked to come forward.
