[1] MEMORANDUM OPINION
[2] While serving a life sentence in the state penitentiary in McAlester, the defendant escaped from the Seminole County Jail, where he had been temporarily transferred pursuant to a writ of habeas corpus ad prosequendum. He was convicted of Escape from a Penal Institution, in violation of Laws 1976, ch. 175, § 1, now 21 O.S.Supp. 1980 § 443[21-443], in Seminole County District Court, Case No. CRF-80-191, and from a sentence of two (2) years' imprisonment, he has appealed.
[3] As his sole assignment of error, the appellant argues that he should have been charged under 57 O.S. 1971 § 56[57-56], Breaking Jail, and that he was thus improperly charged and convicted. This argument must fail. One remains an inmate of a state penal institution, albeit constructively, when he is temporarily absent therefrom, such as in the case before us. Boone v. State,642 P.2d 270 (Okla. Cr. 1982); Goodson v. State, 562 P.2d 521 (Okla. Cr. 1977); McCoy v. State, 536 P.2d 1309 (Okla. Cr. 1975). The appellant was properly charged.
[4] Accordingly, the judgment and sentence appealed from is AFFIRMED.
