Blood spatter patterns are a specialty of analysis in the field of forensic science. Blood spatter analysis relies on the fields of biology, chemistry, mathematics and physics in order to assist investigators in producing evidence.Know More
Blood spatter can be classified into three basic types: passive stains, transfer stains and impact stains. Passive stains occur after the initial incident and are typically the result of gravity, such as droplets of blood on the floor after someone cuts his finger on a blade. Transfer stains occur when a person in contact with blood touches an object to which the blood then transfers, such as blood on a doorknob. Impact stains occur at the initial incident and are the result of the blood being transferred through force, such as blood on the wall behind someone that has suffered a gunshot wound.
