DNA testing of ‘In Cold Blood’ killers can’t link them to Florida murders

Authorities in Sarasota County, Fla., said Kansas killers Perry Smith and Richard Hickock could not be connected to the 1959 slaying of a Florida family. Investigators, working with evidence too old and degraded, could not positively match the pair’s DNA samples to Christine Walker, who was slain with her husband and two children about a month after the Kansas killings.
