In 2018, Orlando police got creative.
Investigators sent the DNA to GenMatch, a voluntary DNA database used by people usually trying to trace their family’s genealogy. In May 2018, the DNA matched to three people who are second and third cousins of the suspect, police said.
After months of hard work and help from the suspect's family, investigators were eventually able to zero in on Benjamin Holmes of Orlando.
Investigators then took his DNA from cigars and a beer can to verify before making an arrest.
Police said Franke's unsolved murder was just one of 15 cases in the country to use this technology. Orlando police said they plan to use the technology to help solve even more cases and may even start a genetic genealogy team in hopes of solving more cases.
