Dr.
Larry Farwell's
Brain
Fingerprinting Test
Helps to Bring a
Serial Killer to Justice

Dr. Farwell conducts
a Brain Fingerprinting test on
serial killer J. B. Grinder
Letter from Sheriff
Robert Dawson on Dr. Farwell's
Brain Fingerprinting test of JB
Grinder
For
15 years, James B. Grinder was the
primary suspect in the brutal murder
case of Julie Helton, but there had
never been enough evidence to bring
him to trial. Miss Helton was
reported missing in Macon, MO in
January 1984. Three days later her
body was found near the railroad
tracks in Macon. She had been raped,
brutally beaten and stabbed in the
neck.
During
the 15 years after the murder,
Grinder had given several different,
contradictory accounts of the crime.
Some accounts involved his
participation and some did not. Some
involved participation by several
other individuals. Grinder's
accounts contradicted both the
physical evidence and the statements
of an alleged witness.
After
spending over 10,000 man-hours
investigating the case, Macon County
Sheriff Robert Dawson asked Dr.
Lawrence Farwell to use Brain
Fingerprinting testing to determine
scientifically whether or not
Grinder was the perpetrator of the
crime. Grinder, already serving time
in jail on an unrelated case, agreed
to participate in the Brain
Fingerprinting test. Sheriff Dawson,
Chief Deputy Charles Muldoon, and
Randy King of the Missouri Highway
Patrol provided Dr. Farwell with the
specific background information on
the case for use in developing the
test. Dr. Drew Richardson, then an FBI Supervisory Special
Agent, worked with
Dr. Farwell to structure the
Brain Fingerprnting test.
During
the Brain Fingerprinting test, which
Dr. Farwell administered in August
1999, Grinder viewed short phrases
flashed on a computer screen, some
of which were probe stimuli
containing specific details of the
crime that would be noteworthy only
to the perpetrator. These included
the murder weapon, the specific
method of killing the victim,
specific injuries inflicted on the
victim by the perpetrators before
she was killed, what the
perpetrators used to bind the
victim’s hands, the place where the
body was left, items that the
perpetrators left near the crime
scene and items that were taken from
the victim during the crime.
Computer
analysis of the Brain Fingerprinting
test found, with a statistical
confidence level of 99.9%, that the
specific details of the crime were
recorded in Grinder’s brain as
“information present”, which means
that record stored in Grinder’s
brain matched the details of Julie
Helton ‘s murder.
Following
the test results, Grinder faced an
almost certain conviction and
probable death sentence. Grinder
pled guilty to the rape and murder
of Julie Helton in exchange for a
life sentence without parole. He
is currently serving that sentence.
In addition, Grinder confessed
to the murders of three other
young women.
Testing Procedure
Dr.
Farwell's Brain
Fingerprintng test followed the
Brain Fingerprinting
Scientific
Standards,
as specified in Dr.
Farwell's peer-reviewed
publications and ruled admisible in
court. Grinder
wore a headband equipped
with sensors that measured
his brainwave responses to
words and
phrases, some of which contained relevant information
to the crime that
was known only to the perpetrator and
investigators.
Test
Results
Grinder’s brainwave responses
to the words and
phrases containing details of
the rape and murder of Julie Helton
clearly contained a P300-MERMER,
indicating “information present” which
means that the details of this crime
were stored in his brain. (As
expected, the target responses also
elicited a P300-MERMER, and the
irrelevant responses did not elicit a
P300-MERMER.)
The Brain Fingerprinting
system mathematically analyzes the
brain-wave responses and makes a
determination of “information present’
or “information absent”. “Information
present” means that the probe
responses, like the target responses,
contain a P300-MERMER indicating that
the crime-relevant information is
stored in the brain. “Information
absent” means that the details of the
crime are not stored in the brain. The
Brain Fingerprinting system also
computes a statistical confidence for
the determination of “information
present” or “information absent.”
The Brain Fingerprinting test
result for J.B. Grinder was
“information present,” with a
statistical confidence of 99.9%. From
this we can conclude with a high
degree of confidence that, even though
fifteen years had passed since the
event, significant details of Julie
Helton’s rape and murder are stored in
J.B. Grinder’s brain.
One week after Dr.
Farwell's Brain Fingerprinting
test on him, Grinder,
faced with certain conviction
and probable death sentence,
pled guilty to the rape and
murder of Julie Helton in a
plea bargain in exchange for
a sentence of life in
prison without parole.
He is now serving
that sentence. He
also confessed to the
murders of three
other young women.
