Yohalmo Godofredo Carrillo-Rivera, a native and citizen of El Salvador, has filed a petition for review of an order of the Board of Immigration Appeals (BIA) summarily dismissing his appeal pursuant to 8 C.F.R. § 1003.1(d)(2)(i)(E). Carrillo-Rivera has failed to brief, and has thus abandoned, the central issue whether the BIA erred in summarily dismissing his appeal on this basis. See Soadjede v. Ashcroft, 324 F.3d 830, 833 (5th Cir. 2003). Accordingly, he has not shown error in the BIA’s decision, and his petition for review is DENIED.
