The Mickey Finn Defense<br />

Case Report<br />

An off-duty police officer met a few<br />

colleagues after work <strong>and</strong> consumed two<br />

beers. Later in the evening, he stopped<br />

off at a topless bar, a known underworld<br />

haunt, for one more beer. After ordering<br />

the drink <strong>and</strong> taking a few sips, he went<br />

to the men's room. He returned to the<br />

bar <strong>and</strong> finished his drink. Within fifteen<br />

or twenty minutes, he suddenly felt as<br />

though his head was spinning. He felt<br />

hot, flushed, <strong>and</strong> dizzy. His throat was<br />

exceedingly dry <strong>and</strong> he had difficulty<br />

swallowing. His heart was beating fu-<br />

riously <strong>and</strong> his vision was blurred. He<br />

remembers staggering back from the bar,<br />

feeling that his mouth was burning, <strong>and</strong><br />

then he blacked out completely. He is<br />

amnesic for the events that followed.<br />

Other observers in the bar noted that he<br />

seemed to be confused <strong>and</strong> delirious. He<br />

staggered <strong>and</strong> strutted around the bar,<br />

shouting (at times incoherently). He<br />

yelled that he was a policeman <strong>and</strong> was<br />

going to "take care of troublemakers."<br />

He waved his gun in a menacing fashion<br />

<strong>and</strong> pointed it at several patrons, causing<br />

them to duck under tables <strong>and</strong> scramble<br />

to safety as best they could. He shot one<br />

of the patrons at point-blank range,<br />

causing serious injuries, for no rational<br />

reason. Then he w<strong>and</strong>ered around the<br />

nearly deserted bar for 10 or 1 5 minutes<br />

in a confused <strong>and</strong> agitated state, appar-<br />

ently unable to find the exit. The police<br />

finally amved <strong>and</strong> placed him under<br />

arrest for attempted murder. Although<br />

he appeared to be intoxicated according<br />

to police reports, no blood tests or urine<br />

screening was camed out for alcohol or<br />

drugs after his arrest.<br />

Prior to the incident described above,<br />

the officer had an unblemished record,<br />

had recently received a promotion, <strong>and</strong><br />

had no history of psychiatric disorder or<br />

substance abuse. The psychiatric expert<br />

retained by the defense (the author) con-<br />

cluded that the defendant appeared to<br />

have suffered an acute confusional state,<br />

most probably a reaction to scopolamine<br />

intoxication, in view of the constellation<br />

of psychological <strong>and</strong> physiological<br />

symptoms he experienced at the time of<br />

the incident. These included confusion,<br />

disorientation, amnesia, delirium, agi-<br />

tation <strong>and</strong> aggressiveness, as well as<br />

flushed skin, dry <strong>and</strong> burning mouth,<br />

palpitations, blurred vision, <strong>and</strong> difi-<br />

culty focusing. He testified that the spe-<br />

cific combination of such symptoms,<br />

both psychological <strong>and</strong> physiological,<br />

was pathognomonic for scopolamine in-<br />

toxication. Because the officer was not<br />

taking any prescribed medications con-<br />

taining scopolamine or related sub-<br />

stances, <strong>and</strong> because scopolamine is not<br />

usually a drug of choice for abuse, the<br />

expert opined that the most likely route<br />

of administration involved surreptitious<br />

addition of the substance to the unsus-<br />

pecting officer's drink. The expert's clin-<br />

ical inferences were based on the offi-<br />

cer's subjective account <strong>and</strong> the objec-<br />

tive observations of third party<br />

witnesses, who confirmed that he had<br />

been highly confused, disoriented, <strong>and</strong><br />

irrational at the time of the incident.<br />

The police had camed out a cursory<br />

investigation <strong>and</strong> failed to seek any in-<br />

dependent corroboration of the officer's<br />

account of the incident. Blood or urine<br />

samples were not collected for labora-<br />
