In a defeat for the prosecution, Judge Debra Nelson ruled that
defense lawyers can introduce evidence that Martin had the active
ingredient of marijuana in his system when he was killed.
Toxicology tests showed a THC in Martin's system, and Zimmerman told
a police operator just before the shooting that Martin "looks like he's
on drugs."
The prosecution argued the evidence was prejudicial, and the defense
countered that it was relevant given Zimmerman's observation that
Martin could be on drugs.
Medical Examiner Shiping Bao initially reported the THC level was
too slight to affect Martin, but Bao testified outside the jury's
hearing last week that his further research in preparation for the trial
indicated the drug might have had a slight but unknown effect.
