From ABC News:
When David Holland gave a voluntary DNA sample last month to help police link his brother to a decades-old unsolved murder, he apparently didn't know it would land him in jail, too.
Investigators suspected Holland's brother Christopher in the 1983 rape and murder of a Santa Clara County, Calif., teenager. Unable to find Christopher, they asked his two brothers for DNA samples last month to try to tie Christopher to the crime.
With the number of rapes that aren't reported at all and the number that aren't reported in time to collect DNA evidence, many rapists may assume they have forever evaded justice. But sometimes justice catches up with those who feel they are above the law.
