Jury selection began Wednesday in a rape case authorities say represents the first time someone has been prosecuted in Los Angeles County based on "genetic fingerprinting" evidence.
Henry Wilds, 33, faces rape, robbery and burglary charges in connection with attacks on two North Hollywood women in 1986 and 1987.
Samples of Wilds' blood were analyzed for genetic makeup and compared to sperm found in each victim.
Scientists say the genetic properties contained in an individual's DNA, or deoxyribonucleic acid, are as unique to each person as their fingerprints.
Superior Court Judge James Coleman ruled last month that the genetic fingerprinting evidence gained from Wilds' blood samples could be presented in court.
"The court found that the technique in question . . . has gained general acceptance in the relevant scientific community," said Deputy Dist. Atty. Lisa Kahn.
Prosecutors had argued during pretrial hearings for admission of the evidence, although Wilds' attorney maintained that genetic fingerprinting is still unproven.
