Alan Lawrence Shelby pleaded guilty to escape from federal custody and was sen- [*204] fenced to 40 months of imprisonment, three years of supervised release, $2,692.60 in restitution, and a $100 special assessment.

Shelby argues on appeal that the district court erred in determining that the instant offense of escape was a crime of violence qualifying him as a career offender under U.S.S.G. § 4B1.1. He concedes that this court held in United States v. Ruiz, 180 F.3d 675, 677 (5th Cir.1999), that escape constitutes a crime of violence under U.S.S.G. § 4B1.2. He argues, however, that Ruiz was effectively overruled by this court’s subsequent decision in United States v. Charles, 301 F.3d 309 (5th Cir.2002) (en banc), because Charles overruled any prior cases conflating the guidelines “crime of violence” definition found in § 4B1.2 and the differing statutory “crime of violence” definition found in 18 U.S.C. § 16. Ruiz did not conflate the definitions of § 16 and § 4B1.2(a). Therefore, Charles did not effectively overrule Ruiz on this basis.

AFFIRMED.
