I think they started doing mitochondrial DNA testing in the 1990s.
The necessary sample size has been steadily decreasing since the 1980s. By the late 1990s, the required sample size shrank to the point where scratched off epithelial cells under a victim’s nails often contained a large enough sample size for testing.
