MEMORANDUM**


2
Parra-Escobedo has fully served the sentence which he challenges on this appeal.   Appellant's Brief at 2.   While any sentencing error the district court may have committed is regrettable, a favorable ruling would no longer be of benefit to Parra-Escobedo.   The federal courts may only entertain live cases and controversies.   See generally U.S. Const. art.  III.  Because Parra-Escobedo "elected only to attack [his] sentence[ ], and since [his] sentence[ ] expired during the course of these proceedings, this case is moot."   Lane v. Williams, 455 U.S. 624, 631 (1982).

DISMISSED.
