What is the evidence available to the sentencing judge for possession of methamphetamine with a street value of at least 9.52 KG?

Evidence available to the sentencing judge strongly supports his determination that Shope possessed at least 9.52 KG of methamphetamine. Police found about 20 pounds of methamphetamine in a safe to which only Shope had access. This evidence would convince a reasonable person that the drugs in the safe and the drugs involved in Shope's conviction were part of a common scheme by Shope to sell methamphetamine. See United States v. Restrepo, slip op. at 4505 (relevant conduct must be proven by a preponderance of the evidence, "a sufficient weight of evidence to convince a reasonable person").
