In an appeal from the judgment of the trial court convicting defendant for dissuading a witness from testifying, Penal Code Section 136.1, and imposing a three-year enhanced sentence, conviction and sentencing are vacated where there was no finding by the jury or the trial court that the witness dissuasion was accompanied by force or a threat of force or violence and because the imposition of the three-year enhancement with a conduct credit limitation was improper since there was no evidence that the witness dissuasion qualifies as a violent felony.
