The Omaha, Nebraska, police were called to Tavares Johnson’s residence to investigate a shooting. Upon arriving at the residence, officers found multiple gunshot victims, including Johnson, who is a paraplegic. Officers were told by a surviv- or of the shooting that gunmen had forced their way into the residence to “jack us” ^[1] for money. In the residence, officers observed two large rocks of a suspected controlled substance lying on a bed next to Johnson and a large caliber pistol lying on the floor. While the officers investigated the shooting, they obtained additional information from a confidential informant who said a paraplegic sold crack cocaine out of the residence.

An officer compiled this information in an affidavit used to obtain a search warrant for Johnson’s residence. During the search, officers found more guns, a small amount of marijuana, and 141 grams of crack cocaine. The discovery of this contraband led to Johnson’s arrest and indictment for several crimes, including possession with intent to distribute crack cocaine. See 21 U.S.C. § 841(a)(1). Prior to trial, the district court ^[2] denied a motion by Johnson to suppress the evidence obtained in the search, rejecting his argument that[*791] the warrant affidavit did not establish probable cause. Johnson then entered a conditional plea of guilty to the possession with intent to distribute charge, reserving the right to appeal the denial of his motion to suppress. See Fed.R.Crim.P. 11(a)(2). We now consider Johnson’s appeal and, after according proper deference to the district court and the court that issued the warrant, we affirm. See United States v. Fulgham, 143 F.3d 399, 401 (8th Cir.1998) (standard of review).

Johnson argues the warrant was not supported by probable cause because the warrant affidavit did not contain sufficient evidence to demonstrate the reliability of the confidential informant. See id. (discussing need for independent evidence to corroborate confidential informant). But, we need not address whether the warrant affidavit sufficiently demonstrates the informant’s reliability, because even without the informant’s tip, the judge that issued the warrant had a substantial basis for concluding probable cause existed. See id. at 400 (evidence admissible if totality of circumstances provided judge issuing warrant with substantial basis to support probable cause finding). “Probable cause means a fair probability that contraband or evidence of a crime will be found in a particular place given the circumstances set forth in the affidavit.” See United States v. Tellez, 217 F.3d 547 (8th Cir.2000) (quoting United States v. Horn, 187 F.3d 781 (8th Cir.1999) (internal quotation marks omitted)). With the police observation of drugs and a gun inside the residence, and information about the “jacking” for money, it was completely within the realm of fair probability that evidence of drug crimes would be found in the residence. See, e.g., United States v. Patterson, 140 F.3d 767, 773 (8th Cir.1998) (presence of large amounts of cash and gun contributes to finding of probable cause). And, even if we thought the warrant affidavit did not establish probable cause, the good faith exception to the warrant requirement would apply because the affidavit was sufficient to allow an officer to reasonably believe probable cause existed. See United States v. Leon, 468 U.S. 897, 923, 104 S.Ct. 3405, 82 L.Ed.2d 677 (1984).

The district court judgment is affirmed.
