This study analyzed 314 suicides by hanging between 2010 and 2014 from the Jurisdiction of Taipei District Prosecutors Office, in order to understand the basic patterns for such cases. Assessment variables included gender, age, marital status, education, mental health, hanging place, use of tools, body posture patterns, leaving a suicide note or not, the past history of suicide, suicide reason, external appearance of inspected corpse. The results are as follows: Male to female ratio was 1.6:1. In the 45-64 age group, the proportion of hanging in female (43.9%) was higher than that in men (31.9%) , but in the 25-44 age group, the proportion of hanging in male (28.8%) was higher than that in female (21.1%). The proportion with presence of suicidal thoughts in female (69.9%) was higher than that in men (56.5%). Female has a higher proportion of suicide past history (37.4%) than male (22.5%). Commit suicide by hanging posture is divided into complete suspension 82 (26.1%), the incomplete suspension 173 (55.1%), and unknown posture 59 (18.8%). The hanging position ratio was 1:2.1. Male selection hanging outside ratio (22.5 %) was significantly higher than that of female (1.6 %). Male in bathroom suicide ratio (3.7%) was far below that of female (17.9 %). Female used scarves, stockings, or cloth roping ratio significantly higher than male, however the use of wire and Scout rope ratio was significantly lower than men. Both male and female with knots located above the occipital for most. The ligature runs from the midline above the thyroid cartilage symmetrically encircling the neck on both sides to the occipital region 217(69.9%).Hanging with point of suspension on front of neck has 3(1%). Ligature mark above the thyroid cartilage 267(85%).In this study revealed the proportion of leaving a suicide note , mental illness, forensic autopsy rate and toxic analysis would be 36%, 46.2%, 1.3% and 1.9%, represently. The cause of hanging related to mental illness / substance abuse occupied the highest proportion (44.3%), followed by physical illness (20.4%). Finally, we suggest that we have to promote the frequency of forensic autopsy and toxicological analysis , which are associated with the scene investigation to determine the cause and manner of death.
