Defendant appeals his convictions of aggravated robbery and felony theft. We reverse.
A robbery occurred at a drive-in theater. An automobile with a male driver and a female passenger stopped by the ticket booth. The driver pointed a rifle at the two attendants and told them to place the theater's money in a bag, which they did.
The two employees in the ticket booth and another witness later identified the woman passenger and the automobile used in the theft, and, although a positive identification could not be made because the man's face had been covered, they stated that various features of defendant matched those of the driver. The identified automobile was later found to be registered to defendant and the woman passenger, and a search of defendant's residence conducted pursuant to a search warrant resulted in the seizure of a rifle similar to that used in the robbery, some money, and the automobile registration.
[1] Although the names of the witnesses were not included, the affidavit stated that they were two of the drive-in's employees and one patron. The name and address of the drive-in are clearly stated and only minimal investigation would be necessary to ascertain the citizen-informants' names. There is no "cloak of secrecy" surrounding the witnesses here, and their identity is sufficiently revealed to presume their credibility and reliability as citizen-informants. People v. Trontell, 188 Colo. 253,533 P.2d 1124 (1975). We also do not agree that the affidavit contained a false statement with respect to the witnesses' identification of defendant. Even though the identifications were not positive ones, the witnesses' statements as to similarities between defendant and the robber suffice to support the affidavit's contents. *Page 286
[3] In considering any affirmative defense, once the defendant has presented some credible evidence tending to support the defense, "then the guilt of the defendant must be established beyond a reasonable doubt as to that issue as well as all other elements of the offense." Section18-1-407, C.R.S. 1973 (now in 1978 Repl. Vol. 8); Wright v. Smith,434 F. Supp. 339 (W.D.N.Y. 1977). See Colo. J.I.-Crim. 7:1. In an alibi situation, unless the court clearly explains that the burden remains on the prosecution, the jury may be given the impression that the burden is on the defendant to prove he was somewhere else, which is not the law. UnitedStates v. Booz, 451 F.2d 719 (3d Cir. 1971), cert. denied, 414 U.S. 820,94 S.Ct. 45, 38 L.Ed.2d 52 (1973). Therefore, giving the alibi instruction without the necessary explanation as to the prosecution's burden relative thereto was reversible error. Cf. McGregor v. People, 176 Colo. 309,490 P.2d 287 (1971); Ortega v. People, 162 Colo. 358, 426 P.2d 180 (1967);Barr v. People, supra.
JUDGE SMITH and JUDGE STERNBERG concur. *Page 287
