In this paper, the effects of the Wigner rotation on the fermion entangled pair are studied in the Rindler spacetime. The spin of the spin particle experiences a Winger rotation under a uniform acceleration. The quantum information of fermions encoded in spin is dissipated by the Wigner rotation as the pair approaches the event horizon. Unlike the case of the scalar particle under the Hawking-Unruh effects in which the mutual information of an entangled pair approaches unity when one of the pair is absorbed by a black hole, the mutual information of a fermion entangled pair experiencing a Wigner rotation converges to zero in the limit of infinite acceleration.
