Nolan traveled by boat with high school friends to Horn Island for a Fourth of July gathering, but the group returned without him. Two days later, Nolan's body was found along the island's shore.

Nolan's family has received support from several prominent Black leaders and public figures. Colin Kaepernick paid for an independent autopsy, while Tyler Perry reportedly covered Nolan's funeral expenses.
