When Penelope was 18, her parents were killed when their vehicle was struck by a drunk driver. The trauma caused her to drop out of school and go “underground” where she taught herself computer hacking. This eventually landed her on an FBI watch list of hackers and eventual recruitment by the FBI. Now, Penelope is an FBI analyst at the BAU Headquarters in Quantico, Virginia. Specializing in accessing secure data and researching suspects for other BAU agents while they are in the field, Penelope is known for her quirky ways of answering her phone.
