We report experimental observations of hexaroll chaos in inclined layer convection. Two separate populations of defect complexes characterize the defect turbulent state, one the classical penta-hepta defect of hexagonal planform patterns, and the other a short-lived complex capable of self-annihilation. By measuring the defect statistics we show that short-lived defect complexes give rise to linear defect destruction rates. This observation explains previous results in other defect-turbulent pattern forming systems.
