The structure and 2α + 2p breakup of $^{10}$C, the only known Brunnian nucleus, has been studied at 33.3 MeV/nucleon. The breakup kinematics were used to reconstruct the $^{10}$C→$^{9}$B +p, $^{9}$B→$^{8}$Be +p, $^{8}$Be→ α + α and $^{10}$C → $^{6}$Be +α, $^{6}$Be → $^{5}$Li +p, $^{5}$Li → α + p decay paths. Proton emission was seen to be favored. The decay of excited states at Ex = 4.20, 5.31, and 6.74 MeV was observed. The previously unobserved state at 4.20 MeV may correspond to a J$^{π}$ = 0$^{+}$α + 2p + α cluster structure.
