We affirm. I. BACKGROUND The defendants were involved in a conspiracy to distribute heroin and cocaine in the St. Louis, Missouri area. The two ringleaders of the conspiracy were Lamond Sykes (a cousin of defendant Sykes) and Eluterio Reyes (“Reyes”). Lamond Sykes led the conspiracy in its distribution of drugs in St. Louis. Reyes, of Phoenix, Arizona, was the main supplier of drugs to the conspiracy. Various members of the conspiracy transported drugs and money between Phoenix, Arizona and St. Louis, Missouri. Other members prepared the heroin for retail sale and distributed the heroin to primary distributors and ultimate consumers. All twenty-one members of the conspiracy, except Jones, plead guilty and were sentenced to various terms of imprisonment ranging from 1 The Honorable John B. Jones, United States District Judge, United States District Court for the District of South Dakota, sitting by designation. 2 The Honorable Catherine Perry, United States District Judge, United States District Court for the Eastern District of Missouri. -2- 18 months to 276 months. The ringleaders, Lamond Sykes and Reyes, were each sentenced to 276 months’ imprisonment. A. Felton Sykes Sykes was charged with participating in the conspiracy from September of 1991 to June of 1994. Sykes was held responsible for distributing approximately 28 kilograms of heroin and 595.35 grams of cocaine. Sykes assisted in the preparation of heroin for retail sale, stored heroin, packaging materials, and money from the sale of heroin at his residence, and met with Lamond Sykes, one of the ringleaders of the conspiracy, to obtain heroin and make payment for heroin previously supplied to Sykes. Sykes was ranked sixth to eighth in culpability amongst the twenty-one defendants charged in the conspiracy. Sykes claims his involvement in the conspiracy ended when he was incarcerated on state drug convictions from October of 1992 to February of 1993. However, a federal search warrant executed in June of 1994 at Sykes’ business and residence resulted in the seizure of over 300 grams of heroin. Sykes does not attempt to explain the existence of this heroin, which was seized over a year after Sykes asserts he ceased participation in the conspiracy. The guideline range for Sykes was 135 to 168 months’ imprisonment. The District Court granted the government’s motion for a downward departure, under U.S.S.G. § 5K1.1 and 18 U.S.C. § 3553(e), based on Sykes’ substantial assistance in the investigation and prosecution of other persons who were involved in the conspiracy. Sykes was sentenced to a term of imprisonment of 84 months, a term of supervised release of 3 years, and was ordered to pay a special assessment of $50. Sykes claims the District Court erred in denying him a minor participant reduction under U.S.S.G. § 3B1.2(b) and the District Court erred in failing to depart sufficiently to cure the disparity in sentences received by Sykes and other, more culpable, codefendants. The government argues that Sykes did not preserve for review -3- the issue of the minor participant reduction and that the disparity in sentences argument has no merit. B. Andrew Jones Jones was charged with participating in the conspiracy from the winter of 1986 to December 22, 1994. Jones was held responsible for distributing approximately 71.5 kilograms of heroin and approximately 595.35 grams of cocaine. The District Court imposed a sentence of 360 months’ imprisonment on the conspiracy count and 240 months’ imprisonment on the distribution count, to be served concurrently; 5 years of supervised release on the conspiracy count and 3 years of supervised release on the distribution count, to run concurrently; and a special assessment of $100. Jones was a street level seller, selling “buttons” of heroin to addicts in the St. Louis area. Terry Martin testified at Jones’ trial that he and Jones, among others, began selling buttons from houses and then sold from vehicles when law enforcement started busting houses where drugs were being sold. Jones was also present on occasions when heroin was being prepared and packaged for retail sale. Jones sought a downward departure on the basis of reduced mental capacity. During the sentencing hearing, Jones called Dr. Daniel J. Cuneo, a clinical psychologist, to establish that Jones was entitled to such a departure. Dr. Cuneo opined that Jones suffered schizo-effective disorder, depressed type, and that he was mildly mentally retarded. He opined that Jones functioned at the level of an eight- or nine-year-old person. Dr. Cuneo determined that Jones had an IQ of 53. The government called Dr. John Rabun, a forensic psychiatrist, to dispute Jones’ claim that he suffered from reduced mental capacity which would entitle him to a downward departure. Dr. Rabun testified that Jones’ alleged conduct of engaging in business activities, including setting up drug buys at specific locations, answering -4- hundreds of pages on his beeper per day and handling large sums of money, are inconsistent with mental retardation. Dr. Rabun also stated that Jones’ conduct in conforming to the conditions of his release on bond and his knowledge of such conditions are inconsistent with mental retardation. Dr. Rabun testified that although Jones has a mental condition, that mental condition did not cause or contribute to his criminal activity. The District Court denied Jones’ motion for downward departure based on reduced mental capacity. After considering the evidence presented by Dr. Cuneo and Dr. Rabun and the arguments of counsel, the District Court did not find that Jones’ mental capacity was significantly reduced or that it contributed to the commission of the offense. Jones raises four issues in this appeal: (1) the District Court erred in admitting guilty pleas of non-testifying codefendants; (2) the District Court abused its discretion in admitting evidence regarding Jones’ uncharged, subsequent drug transactions; (3) the District Court’s finding that Jones did not have reduced mental capacity led it to mistakenly believe it did not have authority to depart for Jones’ mental illness and retardation, therefore, the District Court erred when it refused to depart; and (4) the District Court erred in holding that it could not depart on the basis of the disparate sentences received by others more culpable than Jones.
