Andresen, a senior staff scientist in the Chemistry and Materials
Science Directorate, recently received two awards for the role he
and other Laboratory researchers played in solving a southern California
hospital murder case.
At the Glendale,
California, Police Departments Appreciation and Awards luncheon,
Andresen received a Distinguished Service Award sponsored
by Citizens for Law and Order, a Glendale community group.
He also received a second award from the Glendale Police Department
Homicide Task Force in recognition of his scientific expertise,
dedication and commitment to a complex homicide investigation.
were for forensic science work done by Andresen and his Livermore
colleagues in connection with the Efren Saldivar murder case. In
January 2001, Saldivar, a respiratory therapist, was charged with
using the muscle relaxer Pavulon to kill six older patients at Glendale
Adventist Medical Center in 1996 and 1997.
the assistance of analytical chemist Armando Alcaraz, developed
a way to identify Pavulon in bodies exhumed two to four years after
the crime. Previously, no such techniques were available to detect
Pavulon after such a long time.
In March 2002,
Saldivar pleaded guilty to six murder counts and other charges in
the case for which Andresen and his Livermore colleagues provided
assistance to Glendale police.
early June at the National Conference of the American Nuclear
Society, Livermore chemist Leonard Gray received the
2002 Seaborg Medal for outstanding accomplishment and
meritorious achievement in actinide separations sciences.
Medal was established in 1987 by the University of California at
Los Angeles Department of Chemistry and Biochemistry to honor individuals
for their significant contributions to chemistry and biochemistry.
It is named for the renowned chemist Glenn Seaborg, Nobel Laureate,
former director of Lawrence Berkeley National Laboratory, and former
chairman of the Atomic Energy Commission.
accomplishments include developing processes for the recovery and
purification of plutonium from fuels and reactor targets classified
as nonprocessable by the Department of Energy; developing
chemical processes for the recovery and purification of plutonium
from hard-to-recover plutonium scrap and residues; and
recruiting and leading the international team of scientists and
engineers who developed the ceramic immobilization form for the
disposition of excess weapons plutonium. These and other accomplishments
have decreased nuclear waste or provided it with a disposal pathway
while adding large amounts of recovered or purified plutonium and
other nuclear materials to the nations stockpile.
