As nouns the difference between swipe and wipe is that swipe is (countable) a quick grab, bat, or other motion with the hand or paw; a sweep while wipe is the act of wiping something or wipe can be the lapwing.

Regarding this, what is a wipe pattern?
A wipe pattern is a bloodstain pattern created when an object moves through an existing stain, removing and/or altering its appearance.
Beside above, what are the three types of blood stains? Types of Stains Bloodstains are classified into three basic types: passive stains, transfer stains and projected or impact stains. Passive stains include drops, flows and pools, and typically result from gravity acting on an injured body.
Also Know, what are cast off stains?
Cast-Off Pattern -- A bloodstain pattern created when blood is released or thrown from a blood-bearing object in motion. Directionality -- The directionality of a bloodstain or pattern which indicates the direction the blood was traveling when it impacted the target surface.
What is a swipe in forensic science?
Swipe Pattern - A bloodstain pattern resulting from the transfer of blood from a blood-bearing surface onto another surface, with characteristics that indicate relative motion between the two surfaces. Transfer Stain - A bloodstain resulting from contact between a blood-bearing surface and another surface.

A wipe pattern is a bloodstain pattern created when an object moves through an existing stain, removing and/or altering its appearance.What are the 4 types of passive bloodstains?
- Passive. a. formed from the force of gravity acting alone. b. subdivided (drops, drip patterns, pools, clots) c. oozing or gushes from the body, dripping finger or arm, drops from a knife.
- Transfer. a. wet bloody surface comes in contact with a secondary surface. b. wipe, smudge, swipe or smear. c.
- Projected blood spatter.
What is the drawback effect?
What is the drawback effect? The presence of bubbles of oxygen in the drying drops can differentiate a pattern created by expirated blood, it also may be lighter in color than impact spatter as a result of being diluted by saliva.What are the different blood spatter patterns?
Bloodstains are classified into three basic types: passive stains, transfer stains and projected or impact stains. Passive stains include drops, flows and pools, and typically result from gravity acting on an injured body.What is the point of convergence blood?
Point (Area) of Convergence -- The common point (area), on a two dimensional surface, over which the directionality of several blood drops can be retraced. Point (Area) of Origin -- The common point (area) in a three dimensional space to which the trajectories of several blood drops can be retraced.What are the six patterns of blood spatter?
Bloodstains are classified into three basic types: passive stains, transfer stains and projected or impact stains. Passive stains include drops, flows and pools, and typically result from gravity acting on an injured body.Does height affect blood spatter?
The height from which the blood falls will affect the size of the stain, with greater heights tending to result in larger bloodstains. This type of bloodstain is the result of a forceful impact between an object and wet blood, causing the blood to break into smaller droplets.What is back spatter?
Back Spatter -- Blood directed back towards the source of energy or force that caused the spatter. Bloodstain -- Evidence that liquid blood has come into contact with a surface. Directionality of a blood drop's flight can usually be established from the geometric shape of its bloodstain.What is the difference between the point of convergence and the point of origin?
The origin of a blood spatter in a two-dimensional configuration can be established by drawing straight lines through the long axis of several individual bloodstains. The intersection or point of convergence of the lines represents the origin point. The intersection of the three lines represents the point of origin.How do you collect blood evidence?
Collecting Liquid or Moist Blood – Small Quantity- For each separate blood drop, stain or smear, the investigator should use only one blood swab to collect a sample.
- Allow swabs to air-dry.
- The dried swabs can be placed in a paper container (e.g. paper envelope or bag).
- Properly label and seal the container.
