unusual case

p
lo

ee who wa
s
obviously mentally sick, but successfully evaded detection. The case surfaced with the discovery of
a
p
aper plate containing human feces along with a hand-printed note saying, “The pooper strikes!” The
p
late was d

T
he shocking and repugnant discovery caused alarm and concern among the staff and had
a
negative effect on morale. Over a period of days a succession of plates were found in various location

T
hrough handwriting comparisons, investigators were confident that they had identified the responsi

ble employee, a janitor. The evidence was not conclusive, however. Surveillances failed to catch th

M

a

p
roductive. The
p
roblem was the cul
