The episode takes place on 22 November 1994 - the date it aired- as evidenced by the surveillance camera footage.
Mention is made multiple times that Leticia Beltran attends Skidmore College. This is a private liberal arts college located in Sarasota Springs, NY.
At the 20:00 minute mark, James Martinez and Leticia Beltran enter a park and take a seat on a bench. The park is Christopher Park, part of the Stonewall National Monument, the first national monument dedicated to LGBT rights and history. The area was not designated a national monument until 2016; at the time the episode was filmed, the area would only have been known as Christopher Park. James and Leticia sit near the statues known as the Gay Liberation Monument.
At the 8:30 mark, Christy mentions that her son Nick attends I.S. 27. The real I.S. 27 is the Anning S. Prall Intermediate School, Staten Island, NY. It is named for Anning Smith Prall, a U.S. Representative from 1923 through 1935 and a member of the New York City Board of Education from 1918 through 1921.
