Years after college student says she was assaulted, alleged confession leads to new push for justice: 'It was a sense of validation'

Shannon Keeler is looking for her day in court after eight years.

Nearly eight years after she says she was assaulted, Shannon Keeler says multiple disturbing Facebook messages from her alleged rapist have prompted her to fight for justice and push law enforcement to reopen her closed case. Keller was on a relaxing vacation with her boyfriend last year when she decided to check her Facebook messages for the first time in years. One of the messages stood out to her. She says it was from her alleged rapist, and he was admitting to the attack. Keller says the message read: "So, I raped you. I'll never do it to anyone ever again." "It was a sense of validation," Keeler told ABC News' Erielle Reshef in an interview airing Thursday on "Good Morning America." "I knew immediately that it's not every day that someone gets a confession from the person that raped them, and that no matter what, I had to pursue it again."
