·         Solving crimes relating to the application of series of systematic approach to come up with questions from crime and use it for proceedings.  

Wounds that are incised for suicide victims may refer to the following:
 There is a trial or tentative cut; the characteristic of self infliction is repetition; the usual site is throat and/or wrist; the usually grouped incisions are paralleled; homicidal cut throat is lacking tentative cuts and is severe; homicidal cut throat is usually multiple and irregular; for suicidal cut throat the left side of the neck has a deeper incision for right-handed people and vice versa for left-handed people; most suicidal stabbings do not involve the clothing.

Forensic medical evaluation tools

1.    Weber and Milz Technique (Speed of stabs) Males: 6.14 m/s on dominant hand and 5.27 m/s on non-dominant hand. Females: 4.16 m/s on dominant hand and 3.68 m/s on non-dominant hand. The number of stabs shows some correlation with the gender of the doer. Accordingly there are fewer stab wounds done by females than in homicides that were committed by males. Some inflict a singular stab to their victim and usually if the victim is a male.
2.    Karlsson: Women who killed men usually inflicted 2-9 stabs. Singular stabs occur mostly in sequence of arguments among men under the influence of liquor or other sources of intoxications. The common anatomical distribution of wounds is located at the neck and thorax.
3.    Bajanowski: Wounds and/or injuries are located at the front left side of the trunk in half of the cases. All of the wounds appear to be fatal.
4.    Hunt and Cowling: The common stab wounds found in both sexes are on the neck and chest; the number and location of stab wounds do not conclude the gender of the perpetrator; 15 % of a more than 50 stab wounds are found in the precordial region; 69 % of the cases, wounds and/or injuries are located on the precordial region; 60 % of all cases stabs appear that the stab wounds on the chest decreased in inverse proportion to the total number of stab.

Defense Injuries: these specify evidence of infliction by the perpetrator and ascertain that the victim was conscious and able to defend against an assault to a certain point.
A.   Active defense injuries: often found on the thumb, index finger and related metacarpal regions and near the intermetacarpal space. E.g., Attempts to grab the weapon or the attacker’s weapon-holding hand.
B.   Passive defense injuries are located on the outer portions of the forearms and the back of the hands. E.g., These occur when the victim raises the hands or arms for protection.
Dominant Description of defense injuries: cuts on the hands; increasing number of injuries on the body; stab wounds of the trunk; minor superficial bleeding; most of the blood accumulates in the thoracic and abdominal cavity; traces of blood on clothes from closed injuries.

Common causes of death from wounds and/or injuries: massive bleeding; aspiration of blood; air embolism.

Less frequent cause of death: cardiac tamponade; failure of central regulatory processes.
