Manuel Gatewood pleaded guilty to being a felon in possession of a firearm. The district court sentenced him to 36 months in prison, substantially below the advisory guidelines sentencing range of 63 to 78 months. The United States appeals. We agree the sentence is unreasonable and therefore remand for resentencing.
Gatewood entered a grocery store in Camdenton, Missouri in March 2004. He asked the cashier for change, removing a shotgun from his coat when she opened the register. He stuck the shotgun in the cashier’s chest, said “don’t fucking move,” and grabbed over $1600 from the register. The shotgun had been stolen from a local business where Gatewood formerly worked. After Gatewood pleaded guilty to being a felon in possession, the government dismissed a charge of possession of a stolen firearm. A state charge of robbery was awaiting trial.
The district court held a sentencing hearing two weeks after the Supreme Court’s decision in
United States v. Booker,
Under
Booker,
the sentencing guidelines are no longer a mandatory regime. Instead, the district court must take the advisory guidelines into account together with other sentencing factors enumerated in 18 U.S.C. § 3553(a).
When the district court has correctly determined the guidelines sentencing range, as in this case, we review the resulting sentence for reasonableness. This standard is akin to our traditional review for abuse of discretion. Because the Guidelines are fashioned taking the other § 3553(a) factors into account and are the product of years of careful study, the guidelines sentencing range, though advisory, is presumed reasonable.
See United States v. Lincoln,
For this court to properly carry out the appellate review mandated by
Booker,
it is essential that the district court explain the reasons why it has imposed a sentence outside the guidelines sentencing range in a particular case.
See
18 U.S.C. § 3553(c)(2);
United States v. McMannus,
In this case, the district court sentenced Gatewood only two weeks after
Booker
was decided, before these principles even began to evolve. The court granted a substantial downward variance — forty-three percent below the bottom of the advisory guidelines range — with no explanation of why this sentence is warranted by the other § 3553(a) factors. Moreover, our review of the record suggests that Gatewood is hardly the sort of
*897
felon-in-possession offender who warrants a substantial downward variance. He used a stolen shotgun to aggressively threaten a grocery store cashier while robbing the store. The violent nature of this relevant conduct argues against leniency. Gatewood’s prior criminal history, while not egregious, does not justify extreme leniency. Gatewood argues that the sentence is reasonable because of his history of drug abuse. But the Guidelines prohibit departures based upon drug dependence or abuse because “[sjubstance abuse is highly correlated to an increased propensity to commit crime.” U.S.S.G. § 5H1.4 (policy statement);
see
U.S.S.G. § 5K2.0(d)(l) (policy statement). While a guidelines departure prohibition does not preclude the district court from considering that factor when the issue is a variance under
Booker,
the Sentencing Commission’s policy statements show the need to explain why a particular defendant’s drug problems warrant extreme leniency. Gatewood has a lengthy history of drug abuse without the extraordinary and successful effort to turn his life around demonstrated by the defendant in
United States v. Kicklighter,
On this record, we conclude that the substantial downward variance to a 36-month sentence results in punishment that does not accurately reflect the seriousness of Gatewood’s offense conduct and does not afford adequate deterrence or protect the public from further crimes by this defendant. 18 U.S.C. § 3553(a)(2). In addition, the sentence fails to avoid unwarranted sentencing disparity among defendants with similar criminal histories who have illegally possessed stolen firearms to commit armed robberies.
