Also disclosed yesterday was that police discovered one dose of an injectable form of diphenhydramine, which is more commonly known as the over-the-counter allergy medicine Benadryl. With side effects that include drowsiness and motor-skill impairment, diphenhydramine also is used as a date-rape drug, an FBI toxicologist said yesterday.
However, Marc LeBeau, head of the FBI chemistry lab in Quantico, Va., acknowledged that it could be found in a paramedic's bag. Indeed, it was found by police in the paramedic's bag in Marsalis' University City apartment, and Marsalis used to be a paramedic in Florida.
LeBeau was called by prosecutors to perform an analysis of how much alcohol the seven accusers said they drank the night of their assaults and then compare their likely intoxication with the more severe symptoms they reported, including loss of consciousness.
The alleged victims reported blacking out or losing memory and suddenly finding themselves being raped.
LeBeau said their accounts of what happened were consistent with anterograde amnesia, in which the brain fails to record events although the person might still be conscious. That can be caused by date-rape drugs or extreme amounts of alcohol consumption, he said.
One victim, who was 5-feet tall and weighed less than 100 pounds, testified that she had two gin and tonics before blacking out.
LeBeau said that, for the woman to reach the blood-alcohol levels necessary to start losing memory and blacking out, she would need to have consumed 10 to 12 gin and tonics in the course of two hours.
The prosecution is expected to conclude its case today, and people familiar with the case say that Marsalis' lawyer may mount a defense that is brief enough that closing arguments may also begin today.
