Authorities say Rose raped and fatally stabbed Jean Savage at her Delray Beach home in April 1975.

Authorities had few leads for 40 years, but cold-case detectives processed the old evidence in 2015 and found a DNA match to Rose, who had previously been convicted of murdering an 8-year-old girl in 1975.

Rose admitted to killing Savage, telling detectives that her husband had paid him to execute her.
