These three appeals arise out of the same facts and involve the same issue.1 Two of the appellants were indicted for concealing and facilitating the transportation and concealment of a quantity of heroin, 21 U.S.C.A. § 174, and for introducing and attempting to introduce into the grounds of a Federal Correctional Institution the same heroin, 18 U.S.C.A. § 1791. Jimenez was indicted for the same first count, but the second count against him was for possession of heroin at a Federal Correctional Institution, 18 U.S.C.A. § 13, Vernon's Ann. Tex.Pen.Code, art. 725b, § 2(a). Each appellant was convicted in a non-jury trial and sentenced to ten years on each count, the terms to run concurrently. Each appellant was also subjected to administrative punishment by the loss of accumulated "good time."

The single defense raised by the appellants is that the combination of administrative punishment and criminal conviction placed them in double jeopardy in violation of the Fifth Amendment.2 This contention is without merit. Administrative discipline of a prisoner does not prohibit criminal prosecution for the same event. Keaveny v. United States, 405 F.2d 821, (5th Cir. 1969); Mullican v. United States, 252 F.2d 398, 70 A.L.R. 2d 1217 (5th Cir. 1958); United States v. Shapiro, 383 F.2d 680 (7th Cir. 1967).

The judgment is affirmed.
