dissenting.
I dissent. I am not satisfied that the record in this matter satisfactorily establishes that the subsequent investigation and revocation of Appellant’s parole were not derived from the fruits of Appellant’s own allegedly immunized statements. I believe it to be highly suspect that an offer of use immunity *95was necessary, albeit defective, when the Commonwealth was in possession of independent observations evidencing Appellant’s drinking. This being the case, that separate piece of incriminating evidence should have also fallen under the protective shield of the grant of immunity. Accordingly, I do not believe that the “independently obtained evidence” exception in Riccobene Appeal, 439 Pa. 404, 268 A.2d 104 (1970), relied upon by the majority, applies. Therefore, I would reverse the Superior Court’s affirmance of Appellant’s parole revocation.
