an African-American who challenged Thompson's candidate for the Black vote, and was chased through the streets on polling day by cars of gunmen before being shot dead. Four policemen were among those charged along with Belcastro, but all charges were dropped after key witnesses recanted their statements. An indication of the attitude of local law enforcement toward Capone's organization came in 1931 when Belcastro was wounded in a shooting; police suggested to skeptical journalists that Belcastro was an independent operator. A 1929 report by The New York Times connected Capone to the 1926 murder of Assistant State Attorney William H. McSwiggin, the 1928 murders of chief investigator Ben Newmark and former mentor Frankie Yale. Saint Valentine's Day Massacre Capone was widely assumed to have been responsible for ordering the 1929 Saint Valentine's Day Massacre, despite being at his Florida home at the time of the massacre. The massacre was an attempt to eliminate Bugs Moran, head of the North Side Gang, and the motivation for the plan may have been the fact that some expensive whisky illegally imported from Canada via the Detroit River had been hijacked while it was being transported to Cook County, Illinois. Moran was the last survivor of the North Side gunmen; his succession had come about because his similarly aggressive predecessors, Weiss and Vincent Drucci, had been killed in the violence that followed the murder of original leader Dean O'Banion. To monitor their targets' habits and movements, Capone's men rented an apartment across from the trucking warehouse and garage at 2122 North Clark Street, which served as Moran's headquarters. On the morning of Thursday, February 14, 1929, Capone's lookouts signaled four gunmen disguised as police officers to initiate a "police raid". The faux police lined the seven victims along a wall and signaled for accomplices armed with machine guns and shotguns. Moran was not among the victims. Photos of the slain victims shocked the public and damaged Capone's image. Within days, Capone received a summons to testify before a Chicago grand jury on charges of federal Prohibition violations, but he claimed to be too unwell to attend. In an effort to clean up his image, Capone donated to charities and sponsored a soup kitchen in Chicago during the Depression. The Saint Valentine's Day Massacre led to public disquiet about Thompson's alliance with Capone and was a factor in Anton J. Cermak winning the mayoral election
