Published: Friday, August 14, 2015, 2:31 PM  Updated: Saturday, August 15, 2015, 12:26 AM  A bloodthirsty gunman chased three men into the cramped foyer of a Brooklyn apartment building before blasting away at his victims — killing one of them, a stunning video released Friday shows.  Cops released the video of the doo-rag sporting killer in the hopes it will help solve the murder of Isaiah Cicero, 21, who was shot in the chest and died during the fatal confrontation on Saratoga Ave. near Livonia Ave. about 8:15 p.m. Thursday.  The gunman stepped out of a dark-colored Mitsubishi before chasing Cicero and his two friends into the building, officials said. Once inside, he squeezed off three rounds, hitting Cicero in the midsection. Taariq Smith, 20, and Sydney Mylles, 18, were both shot in the arm. Cicero died at Brookdale University Hospital, officials said. Smith and Mylles’ injuries were not life threatening, cops said.  A motive for the shooting was not immediately established, according to police sources. The two surviving victims have not been cooperating with investigators, sources said.  The gunman remained at large Friday night.  In an unrelated incident about eight hours later and a mile away, a gunman shot and killed Clifford Fisher, 25, inside the Howard Houses on Mother Gaston Blvd. in Brownsville.  Fisher was shot in the head about 4:45 a.m., officials said. He was rushed to Brookdale University Hospital, but could not be saved.  Cops are asking anyone with information regarding either slaying to contact Crime Stoppers at (800) 577-TIPS. All calls will be kept confidential.  ON A MOBILE DEVICE? WATCH THE VIDEO HERE.
