Although the victim, Oscar, is identified throughout as the brother of Sgt. Julio Sanchez, in her first interview with the suspect, "Puppet," Brenda Leigh calls him the brother-in-law of Sanchez.
When Sanchez calls Tao, he asks him to "send units to First and Indiana;" however, as the ambulance pulls up, you can see a street sign showing they are at the 5000 block of Clinton, so they are actually at N. Gramercy and Clinton Street.
