United States v. Tucker, 740 F.3d 1177 (8th Cir. Jan. 29, 2014) (under the Supreme Courts decision in Descamps, the court may not apply the modified categorical approach to a statute that is textually indivisible, such as the Missouri statute penalizing a walk-away escape from a half-way house, to hold the offense to be a crime of violence under the residual otherwise clause of the ACCA, 18 U.S.C. 924(e)(2)(B)(ii), because there was a guard on duty when the escape occurred); partially overruling United States v. Parks, 620 F.3d 911 (8th Cir. 2010) (holding that a walk-away escape from a halfway house was a crime of violence under the Career Offender Guideline, applying the modified categorical approach to determine that Parkss escape offense posed a substantial risk of physical injury to another, because there was a guard on duty at the entrance of the halfway house when Parks walked away, even though the Missouri statute did not make this an element of the offense).
