Exclusion of a man charged with murder by DNA fingerprinting.

DNA fingerprinting was used to demonstrate that two murder-rapes committed in 1983 and 1986, respectively, were connected. The probability of chance association of the fingerprint was calculated as 5.8 x 10(-8). The man who had been charged with the murder was excluded because his DNA fingerprint did not match sperm DNA fingerprints obtained from swabs and clothing attributed to the two victims.
