MEMORANDUM *

Jimmy Bernal Avendano appeals the district court’s denial of his motion to suppress statements he made during an interrogation and his motion to dismiss the indictment. We have jurisdiction pursuant to 28 U.S.C. § 1291 , and we affirm.

Even assuming Avendano was arrested illegally, his statements were admissible. His confession occurred after probable cause had developed independently of the arrest. 1 Moreover, authorities did not obtain his confession by any “exploitation of the possible illegality of his arrest.” 2 Thus, the district court properly denied Avendano’s motion to suppress.

We have conclusively rejected the first ground on which Avendano moved to dismiss the indictment. 3 Another case precludes the second ground. In United States v. Armstrong, 4 we held that the aiding and abetting theory “is implied in every indictment for a substantive offense.” 5 Armstrong did not merely address jury instructions, as Avendano argues, it controls. 6 Accordingly, the district court properly denied Avendano’s motion to dismiss.

AFFIRMED.
