Police in Los Angeles say that DNA links a 72-year-old state insurance claims adjuster to five and, perhaps as many as 30, killings that took place in two waves in the mid-1970s.
The first wave of killings, the killer preyed on older women who he raped and squeezed their necks until they passed out died. Seventeen women were killed.
In the second wave of killings, five older women were raped and strangled. In both killing sprees, the victims' faces were covered with pillows or blankets.
Authorities say they now suspect John Floyd Thomas Jr., who twice has been convicted of sexual assault, in five of the killing and, perhaps, 25 more, the Los Angeles Times reported.
