  An interaction of upstream extra particles with a monolayer highly-ordered
complex plasma is studied. A principally new abnormal turbulent wake formed
behind the supersonic upstream particle is discovered. An anomalous type of the
turbulence wake clearly manifests in anomalously low thermal diffusivity and
two orders of magnitude larger particle kinetic temperature compared to that of
the 'normal' wake (Mach cone) observed by Du et al [Europhys. Lett. 99, 55001
(2012)].
