Rebecca Trayers

Rebecca Trayers worked as a bartender at the Waterfall Bar & Grille in Canton, Massachusetts, and was on duty the night John O'Keefe was last seen alive in a social setting. She testified about the bar's layout, surveillance cameras, and the patrons present that evening, placing O'Keefe alongside Brian Albert, Brian Higgins, and others at a high-top table in the lounge. Her testimony established the physical environment and social dynamics of the group's final hours at the bar before they moved to the Albert household.
