Notes are found in only a minority of cases of suicide and occasionally may involve writing messages on skin surfaces. A prospective study was undertaken for cases of suicide with skin messaging over a 12-year period from 1/1/2000 to 31/12/2011. A total of 498 cases of suicide were examined with only 2 cases (0.4%) having suicide notes written on their skin. Both cases involved young males (aged 18 and 30 years respectively) with the deaths occurring by hanging. In both cases typical parchmented ligature marks were present around the neck running up to the point of suspension. Both decedents had written messages on their hands/arms expressing mixtures of sorrow and hopelessness. There were no other suicide notes present. It is not clear whether writing on skin rather than on more conventional material suggests that the suicide may not have been planned, or instead that the decedent wanted to ensure that the message was found. Messages on skin may be slightly different to messages written on other surfaces, as space is limited and pens and markers may not write as effectively. An additional problem with skin messages is their vulnerability to erasure, making clear documentation of these findings at the scene important.
自杀案例中仅有少数会留下遗书,偶尔还可能包括在皮肤表面书写信息。对2000年1月1日至2011年12月31日这12年间有皮肤书写信息的自杀案例进行了一项前瞻性研究。共检查了498例自杀案例,仅有2例(0.4%)在皮肤上写有遗书。这两例均涉及年轻男性(分别为18岁和30岁),均系上吊死亡。两例颈部均有典型的羊皮纸样勒痕,向上延伸至悬吊点。两名死者均在手部/手臂上书写了表达悲伤与绝望交织情绪的信息。未发现其他遗书。尚不清楚在皮肤上书写而非在更传统的材料上书写是表明自杀可能并非经过预谋,还是相反,表明死者希望确保信息被发现。皮肤上的信息可能与写在其他表面的信息略有不同,因为空间有限,笔和记号笔可能书写效果不佳。皮肤信息的另一个问题是容易被擦掉,因此在现场清晰记录这些发现很重要。
