MANATEE COUNTY - The Innocence Project of Florida has a record of using
powerful new evidence to overturn wrongful convictions, but that does
not mean prosecutors give up easily.
Most of the time, state attorney offices will do what Manatee County
prosecutors did in court Friday in the case of Derrick Williams --
fight to uphold a conviction that is years old, even as exculpatory
evidence mounts.
"Nobody wants to think they or their office could have had a part in
wrongfully convicting somebody," Florida Innocence Project Executive
Director Seth Miller said. "The more notoriety we have, that creates
more reluctance because of the result we're seeking."
The project says new DNA evidence on a key piece of evidence -- a gray
shirt -- proves Williams was wrongfully convicted of a rape in Palmetto
in 1993.
But prosecutors argue the evidence at trial was so overwhelming that
DNA tests would not have affected the jury's guilty verdict.
Some inmates have had prosecutors deny their requests for DNA tests
repeatedly, until the Innocence Project gets involved.
Friday's hearing cleared up some last legal issues before a main
hearing scheduled for March, which will determine if Williams should be
exonerated, face a retrial, or have his appeal denied.
Police accused Williams, now 47, of abducting the 25-year-old woman
from her Palmetto home, forcing her into her car and driving her to an
orange grove to rape her.
Williams testified at his trial; relatives told the jury he was at a
family barbecue at the time of the attack.
Williams immediately offered to give blood and saliva samples, but no
sperm was found to compare the genetic material, and DNA techniques
used to find samples on evidence were not known then.
So the case largely was based on the victim's identification of
Williams, but her description of her assailant differed from Williams
and her story was inconsistent. Misidentification is often the cause of
wrongful convictions, the Innocence Project said.
Innocence Project involvement brings extra publicity to appeals, and
has led to a reputation for taking strong cases with new physical
evidence such as DNA.
The Innocence Project called on prosecutors to immediately release
Williams last year.
But revelations over new evidence do not automatically mean prosecutors
will relent and agree to release inmates.
"The prosecutor is supposed to do justice," said Chip Thullbery, a
spokesman for Polk County State Attorney's office, where the Innocence
Project overturned James Bain's rape conviction after 30 years.
"If justice means upholding the jury's verdict because the defendant is
making a frivolous objection, that's what the prosecutor should do."
On Friday, Manatee County prosecutor Spencer Rasnake fought to prevent
the Innocence Project from using the original police records from
Williams' case to argue for his freedom.
Rasnake said the appeals based on new evidence are "difficult to do."
But in this case he does not think the new evidence would have changed
the result at trial.
The Innocence Project says those records contain incorrect information
and evidence of sloppy police work.
Rasnake says those materials were available during Williams' trial in
1993, and are not generally admissible at a trial, so they should not
be used to overturn the conviction.
The judge will decide the issue before the March hearing.
