3

Identify and match the forces affecting blood spatter to their proper descriptions.

Draggable item		Corresponding Item
gravity		the attraction between molecules of like substances; gives blood a domed shape when resting on a surface
cohesion		the attraction between molecules of unlike substances; causes blood to cling to porous surfaces
adhesion		the force of attraction between the earth and another object; gives falling liquids a tear-dropped shape

Identify the various bloodstain patterns shown in the photograph.

Mmuae Afoforo a Wobɛpaw:

passive drops

void

pattern transfer

1

Satellites occur when a droplet of blood strikes a surface, _____.

but some of the blood overcomes cohesion and separates from the main droplet of blood

and portions of the blood still connected to the droplet extend beyond the droplet

and the droplet elongates or extends due to an uneven or possibly porous surface

and the point of impact extends the droplet in the direction that the blood was travelling

During the walk-through of a crime scene, an investigator would consider the possibility that _____.

the victim was dragged if a hair swipe pattern is present

transfer patterns indicate a victim was struck and the number of blows

furniture was moved after the crime if a blood trail is present

cast-off patterns indicate where to locate a moving victim
