Person of interest, Sam Groves
Samantha Groves, known then as Sam, was born in Bishop, Texas, and lived there until her mother's death around 2002. Her mother taught her to follow her talents, which are computers. As a child, computers made more sense to Sam than people.
One afternoon in 1991, Sam and her friend Hanna Frey are in the local library. As Sam looks for a book, Hanna unsuccessfully plays the simulation computer game "Oregon Trail" until the library closes for the day. After Hanna leaves, Sam stays behind, quickly finishing the game with apparent ease. As Sam leaves the library, she sees Hanna getting into a car that belongs to Trent Russell, a local man who is a member of the library's book club.
She recognizes his car and tells the librarian, Barbara Russell, what she has seen. However, because Barbara is in love with Trent, she scares Sam into keeping what she saw to herself. ("Bad Code") Hanna is never seen or heard from again.
