Authorities in California's Bay Area are one step closer to solving a 1973 cold case killing of a 21-year-old woman after genetic genealogy led investigators to an arrest this week. Deputies from the Santa Clara County Sheriff's Office arrested 74-year-old John Arthur Getreu Tuesday in connection with the murder of 21-year-old Leslie Marie Perlov, authorities announced.
