Lolita Cortes is a Colombian-American escort in the Metro area.
Having immigrated to the United States at 18 years old, she ended up becoming a prostitute, which resulted in her being arrested twice.
She was eventually recruited by Navy Lieutenant Louis Freston, under the alias of Petty Officer Daniel Harvey, to go to Colombia in order to retrieve a DNA sample of Tomás Orlando for Operation Lex Talionis, returning after two days in the country.
She then met with Daniel Harvey, requesting that her family be protected.
Unfortunately, before she could supply the DNA sample, etched into her purse, she ended up being gunned down alongside Harvey by her pimp, Eddie Rosario, in order to set an example to his other charges nearby (as she had earlier had a falling out with him, and he evidently didn't like that).
In addition, her purse ended up stolen by Collarbone shortly thereafter, although he was unaware of its connection to a Navy operation or what was inside it.
Orlando, after surrendering to NCIS, then proceeded to reveal that Lolita's family informed her about the girl retrieving his DNA sample, which caused him to realize he had been set up for the Metropolitan Airport Bombing.
