CAMPBELL, Calif. — When David Pearman gave investigators a sample of his DNA, he knew it might help them link his older brother to the brutal 1983 rape and murder of a Campbell teenager.
But last week, detectives came knocking at Pearman's door again. This time, they said, his DNA had connected Pearman to a separate horrendous crime - the rape of an 81-year-old San Jose woman.
