Tim Sharp was shocked when he heard from his aunt last month that the
woman who had killed his father in a drunk-driving accident was up for
parole. The inmate, Maelene Chambers, had served only four years of a
10-year manslaughter prison sentence for the 2006 death, and Sharp knew
that manslaughter was one of more than 20 state crimes in which
offenders were required to serve at least 85 percent of their sentence.
