Police collected the shotgun and the expended shells from the .45-caliber pistol that Davis took with him. A .32-caliber revolver and .357 Magnum pistol were also left behind. Ballistics tests would later link the .32-caliber revolver to the Manhattan drug dealer killing and the .45 caliber pistol to the four dead Bronx dealers. A police official said that all escape routes had been covered by officers but none apparently saw Davis leave. He also said that the wounded officers were unable to return fire effectively due to the presence in the apartment of the two infants and other bystanders. Davis fired four shotgun rounds and nine .45 caliber pistol shots; the police fired four shotgun rounds and 20 pistol shots. Neither Davis nor the two infants with him in the bedroom were wounded.
