LA County Sheriffs Office Fighting Crime with ISYS
The LA County Sheriffs Office is very
excited with its plans for the implementation of ISYS across the entire
Crime Analysts' division. Having purchased a license for 25 concurrent
users, ISYS will provide a faster, more accurate method of cross-referencing
data as well as facilitating the introduction of electronic search capabilities
for crime files stretching back as far as ten years.
The Crime Analyst is described by Mr.
Steve Sullivan, one of the administrators for the site, as part computer
detective and part soothsayer. These people assist the investigators with
Crime Analysts create criminal profiles
from databases and other information using statistical and intelligence
analysis methods. In the case of serial killers, they attempt to predict
the next move of the murderer.
A lot of their work is incident-based
and Analysts attempt to identify criminals based on the information available.
With the introduction of ISYS, the Sheriffs
department can now access information that they have never been able to
before. Because ISYS does not require a structured database, text documents,
bulletins and other miscellaneous information can be accessed and efficiently
Because the analysts have never had this
type of query available before, their information base needs to be built
up. The department is working on reloading archived information back onto
their computers. They are currently reloading records from June 97 and
have tested the ISYS index on electronic documents that are ten years
old. ISYS successfully indexes these documents so plans are in place to
reload crime files for the entire ten year period.
When complete, this knowledge base will
be able to assist with re-offenders as well as increase productivity on
new cases. The advantages with re-offenders are that where a person has
committed a crime, gone to jail and been released, the information will
still be on the computer.
When a new crime occurs, the Crime Analyst
can search old documents, bulletins and databases for characteristics
of that crime. They can search for elements of the modus operandi,
words or phrases mentioned during the crime or a particular weapon. ISYS
can bring up an old crime record that matches the details and a re-offender
can be quickly identified.
The Sheriffs office is still in the developmental
stage of creating this knowledge base but anticipates some great results.
ISYS will become an integral tool in the fight against crime.
