The men were among several killed in a May 22 plane crash near San Diego. Both were at Pierce the Veil's sold-out MSG show. Here's what to know.

Pierce the Veil are a group Shapiro worked especially close with as their agent, manager and friend. He attended the band's sold-out show this past Tuesday at New York City's Madison Square Garden, and flew out of New Jersey's Teterboro Airport the following night to head back home.

Shapiro, who was also a pilot, booked Pierce the Veil, Streetlight Manifesto, The Acacia Strain, Armor for Sleep, and numerous other bands.
