Jeena Han had overcome a difficult childhood to become co-valedictorian at her high school, just like her twin sister Sunny. The South Korean native seemed headed for success. Then, 23-year-old Jeena developed a gambling habit and began stealing and forging checks to pay her debts. When she needed help, her sister Sunny took her in. But sibling rivalry and close quarters proved too much. Their volatile relationship drove them apart. In November of 1996, two assailants bound and gagged Sunny and her roommate, but police intervened before they were harmed. Cops quickly traced the murder attempt back to Sunny's twin sister, Jeena. Prosecutors say it was part of a devious plan to assume Sunny's identity and leave the country. Jeena and her two accomplices were tried and convicted. She is serving 26 years to life in prison.
