"DNA from Chewing Gum Leads to Conviction in 1980 College Student Murder"

Robert Plympton, a man living in Oregon, has been found guilty of the 1980 murder of college student Barbara Mae Tucker after DNA from a piece of chewing gum linked him to the crime. The breakthrough in the cold case came from DNA technology that was not available over 40 years ago, and a genealogist with Parabon Nanolabs identified Plympton as likely linked to the DNA in the case. Plympton was not convicted of rape or sexual abuse due to lack of evidence, and he is scheduled to be sentenced in June.
