On another crime show the other night (I seem to watch a lot of these), the original suspect told a 911 operator that she had observed blood on her murdered friend's "headboard." This word somehow got transcribed as "forehead," however, and became a major part of the state's case against her. The investigator argued that the witness couldn't possibly have seen the victim's forehead since the body had been completely wrapped in trash bags and blankets. It's hard to know whether he made that error by mistake or on purpose, but if the latter, it was evidently an ingenious, if thoroughly corrupt, move, allowing for a certain plausible deniability. (Oops, typo!) In any case, it underscores the often critical importance of proofreading one's records; it can actually be a matter of life and death. We uncovered evidence of Eveden* twice in OhioLINK, and 57 times in WorldCat.
