Author: NBC News July 23, 2025 Duration: 21:07
Josh Mankiewicz and Keith Morrison sit down to discuss Keith’s episode “Secrets of the Sliding Door.” When beloved Staten Island teacher Simeonette “Sissy” Mapes-Crupi was found murdered in her home, investigators never imagined an escort by the name of Ms. Pumpkin would help lead them to her killer. Josh and Keith discuss the different theories of the crime and play an extra clip from interviews with Simeonette’s friends and family. Plus, they talk phony-sounding 911 calls, answer a listener question about detecting lies during interviews, and take a deep dive into Keith’s sneaker collection.
