Blanco v. Mukasey, 518 F.3d 714 (9th Cir. Mar. 3, 2008) ("Because the record here does not include any of the documents that would allow us to conduct a modified categorical analysis, we employ only the categorical approach. See United States v. Vidal, 504 F.3d 1072, 1086 (9th Cir.2007) (en banc) (noting that when conducting a modified categorical analysis, the court's review is "limited to examining the statutory definition, charging document, written plea agreement, transcript of plea colloquy, and any explicit factual finding by the trial judge") (internal quotation marks omitted).").
