June Gibbons and Jennifer Gibbons were identical twins who grew up in Wales. Bullying in their young years caused them to be secluded, and cast out. This caused the twins to speak only to one another in a language they created. However, both girls had underlying feelings of hatred towards one another. They ended up turning to petty crimes, where they ended getting admitted to the mental institute. In the end Jennifer died a peculiar death, but it was deemed only natural. However, the suspicious circumstances around it continue to raise eyebrows.
