Bloodstain Pattern Analysis: Forensic Types & Classification
On the basis of the velocity of the force impacting a bloody object spatter is classified as follows: 1. Low-Velocity Spatter. These are large separate or compounded drops caused by an impact of fewer than five feet per second; blood cast off from a fist, shoe, weapon, dripping, or splashing.
Bloodstain Pattern Analysis - Forensic Science Simplified
Blood spatter is categorized as impact spatter (created when a force is applied to a liquid blood source) or projection spatter (caused by arterial spurting, expirated spray or spatter cast off an object). The characteristics of blood spatter depend on the speed at which the blood leaves the body and the type of force applied to the blood source.
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.

2023年2月21日 · The size, shape, location, and distribution patterns of blood stains found at a crime scene can help to determine the sequence of events, the approximate locations of blood sources, the position of the victim, the type of weapon used, intensity and number of impacts applied to the blood source, etc.
Bloodstains - Crime Scene Forensics
SPATTER VS TRANSFER: The simplest type of blood spatter analysis is determining spatters from transfers. Spatters are created when blood is acted upon by force, and travels through the air before landing on a target surface. Transfers occur when a blood source comes in direct contact with a target surface area.

2020年2月7日 · There are many classifications given by blood spatter analyst around the world. I will be using the most common here, to make it understand in a lucid form. Passive Blood Pattern: In the form of flow, pool, saturation, drip/drop, volume. Projected Blood Pattern: Instrumental, expirated, arterial spurt/gush.

2019年12月9日 · We classify bloodstains into three main categories; Passive Stains: These occur with indirect forces such as gravity acting on the injured body. These can be drops, flows and pools. Transfer Stains: These occur by objects or surroundings coming into contact with the blood.
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.
