California man found guilty of two 1980s murders thanks to new DNA technology

In 2006 detectives discovered DNA evidence, but it was 12 more years before they could identify suspect using genealogy websites

Prosecutors in California secured the conviction of a 1980s double murderer after the first use by Los Angeles county detectives of online genealogical databases to identify a suspect.

Horace Van Vaultz, now 67, killed Selena Keough, 20, in Montclair in 1981, and Mary Duggan, 22, in Burbank in 1986, but escaped justice for 36 years until investigators were able to link him to DNA from the victims.
