In February 1990, police executing a search warrant in the basement of an apartment building in Boston, Massachusetts found several bags of cocaine. A resident of the building said she had seen Humberto Guzman and two other men in the basement sometime after Christmas. Based on this information, police searched Guzman’s home and found a pager, cash and other items. A caller to the pager attempted to purchase cocaine from “Humberto.” Police arrested the caller and offered a deal if the caller would arrange a sale with “Humberto”. The caller and another man completed the transaction with Humberto, and the police later arrested Guzman. Guzman claimed that he was out of the country at the time of the sale and his cousin was using his name and apartment to conduct drug deals. The officers and the resident of the building they spoke to were the only witnesses connecting Guzman to the drugs found in the apartment building. Guzman’s attorney failed to call the two men who purchased the cocaine because he had previously represented them on unrelated charges and was afraid the judge would remove him from Guzman’s case. The two buyers would have testified that Guzman was not the seller. Further, Guzman’s attorney successfully prevented the prosecution from calling one of the men to testify. In January 1992, a jury found Guzman guilty of trafficking in cocaine and conspiracy to traffic in cocaine. Guzman appealed based on the ineffectiveness of his defense attorney, and in October 1994, the trial judge overturned his conviction and granted his motion for a new trial. The state appealed, but the Massachusetts Appeals Court affirmed the granting of a new trial in May 1996. In March 1997, before Guzman was retried, the two police officers who testified against him were indicted by a federal grand jury and pled guilty to charges, including planting drugs and evidence. Guzman filed a motion to dismiss the indictments against him, which a Superior Court judge granted in March 1997. The prosecution did not refile the charges.
