Solis served 17 years in prison for murdering a security guard during a robbery in 1969. He was given parole in 1992. Following his release, he met Heather Tallchief, who became employed by a security company at his urging. In October 1993, following Solis' instructions, Tallchief drove away in an armored vehicle containing $2.5 million. The two subsequently went on the run and had a child. Tallchief gave herself up in September 2005, but Solis is still at large.
