Matter of Velazquez-Herrera, 24 I. & N. Dec. 503, ___ (BIA May 20, 2008) ("We are mindful of the fact that the respondent entered his plea to a charge that clearly identified his victim as a child. The language of that charge may well have been significant because the Supreme Court has explained that "the details of a generically limited charging document" are generally sufficient "in any sort of case" to establish "whether the plea had necessarily rested on the fact identifying the [offense] as generic." Shepard v. United States, supra, at 21. Yet as all parties recognize, we are precluded from relying on the original charge because, after these proceedings commenced, the State prosecutor removed all traces of the victim's juvenile status from the amended information and then interposed the expurgated, back-dated charge into the conviction record.").
