Bloodstain Pattern Analysis Terminology - IABPA - Low Velocity Impact Spatter (LVIS) |
Note: At the 2009 IABPA meeting in Portland, OR, USA, the IABPA membership voted to adopt the SWGSTAIN recommended terminology. Definition- Low Velocity Impact Spatter (LVIS)
- A bloodstain pattern that is caused by a low velocity impact/force to a blood source.
 Bloodstain Example - Low Velocity Impact Spatter (LVIS)© 2008 FORident Software Inc. Description
This pattern was generated by stepping onto a small pool pattern on the target.
Low velocity impact spatter (LVIS) is generally produced by objects travelling less than 1.5 m/s.
The majority of stains in this pattern are larger than 3 mm in diameter.
There may also be spines radiating from the parent stain. In this example, the shoe came
in contact with the bottom portion of the pool first. |
