A lot of thing can influence a person to commit arson (criminal damage act). Usually its to cover up a murder but that isn’t helpful; because human bones don’t fully burn up into dust. And that can leave behind important evidence that can help solve a case. For example someone was stabbed with a knife the knife marks between two rib bones can identify the length, width and sometimes the type of knife just by the marks on the bones. Another example would be Rage, or even for fun. and a thing that scary even firefighters have been known to start commit arson for gratification for example firefighters would set fires and then go in and save the people in side. And even if there’s a lack of fires firefighters will go an commit arson. But you can rest assured that a firefight probably won’t commit arson it is very rare for this to happen.

Thinking about pursuing a career in forensics but don’t want to deal with blood and dead bodies. Well here are some careers without that, Computer forensics, Forensic art, DNA technician (although you may encounter some blood),Ballistics (a person who works with bullets and guns) and if you don’t mind blood and dead bodies here are some careers you may like Forensic investigator, Crime scene investigator, and Criminologist. Below are two websites to help you learn more

Transfer/Contact bloodstains A transfer or contact stain is produced when an object with blood comes in contact with an object or surface that does not have blood. It may be possible to discern the object that left the blood impression. Wipe Pattern – A bloodstain pattern created when an object moves through an existing stain, removing and/or altering its appearance. Swipe Pattern – The transfer of blood from a moving source onto an unstained surface. Direction of travel may be determined by the feathered edge. As indicated above, there are other terms currently used in BPA and different ways of classifying bloodstain patterns. For example there is a debate over the misnomer of the LVIS, MVIS, and HVIS as it relates to the physical term ‘’velocity’’. A sub-committee of the SWGSTAIN has been tasked with addressing the terminology issues and develop a taxonomy for bloodstain patterns.

Low velocity impact spatter Low velocity impact spatter (LVIS) is generally produced when objects traveling less than 1.5 m/s come in contact with a blood source. The preponderance of stains is generally larger than 3 mm in diameter.

Medium velocity impact spatter Medium velocity impact spatter (MVIS) is generally produced when objects traveling between 1.5 m/s and 7.5 m/s come in contact with a blood source. The preponderance of stains is generally between 1 mm and 3 mm in diameter. Mechanisms that could produce this type of pattern include blunt force trauma or cutting/stabbing actions.

High velocity impact spatter High velocity impact spatter (HVIS) is generally produced when objects traveling greater than 30 m/s come in contact with a blood source. The preponderance of stains is generally smaller than 1 mm in diameter. This pattern often has a mist-like appearance. High velocity patterns may be created by gunshots or explosives, but may also be caused by industrial machinery, coughing, or sneezing.

Passive bloodstains Passive bloodstains are those stains created by the force of gravity. Passive Drop – Bloodstain drop(s) created or formed by the force of gravity acting alone. Drip Pattern – A bloodstain pattern which results from blood dripping into blood. Flow Pattern – A change in the shape and direction of a bloodstain due to the influence of gravity or movement of the object. Pool Pattern – A bloodstain pattern formed when a source of blood is stationary for a period of time.

Projected bloodstains A projected stain occurs when some form of energy has been transferred to a blood source. Low Velocity Impact Spatter (LVIS) – A bloodstain pattern that is caused by a low velocity impact\force to a blood source. Medium Velocity Impact Spatter (MVIS) – A bloodstain pattern caused by a medium velocity impact\force to a blood source. A beating typically causes this type of spatter. High Velocity Impact Spatter (HVIS) – A bloodstain pattern caused by a high velocity impact\force to a blood source such as that produced by gunshot or high-speed machinery. Cast-Off Pattern – A bloodstain pattern created when blood is released or thrown from a blood-bearing object in motion. Arterial Spurting (OR Gushing) Pattern – Bloodstain pattern(s) resulting from blood exiting the body under pressure from a breached artery. Back Spatter – Blood directed back towards the source of energy or force that caused the spatter. Expiratory Blood – Blood that is blown out of the nose, mouth, or a wound as a result of air pressure and/or air flow which is the propelling force.

 Fingerprinting, i’ve learned that fingerprinting can be done by just about anyone. Fingerprinting is not hard if you know the technique that being, Holding the fingerprint brush at a slight 45 degree angle and using a spinning motion rather than a sweeping motion. Now you need powder you can get finger printing kits at sciences stores or you can get a children’s finger print kit from a toys r us which work the same. or you can buy baby powder(talcum powder) and by going to a printer store you can get ink powder which works all the same. for a brush to get a good proper one you can buy it of the Internet. but anyway here’s ho you do it put the brush into a jar of powder the techniques the same for all colors of powder and gently twirl the brush around until a print appears then blow the extra powder off with a mechanical blower not your mouth because saliva can hit the print and wreck it. Then using wide clear scotch tape and gently apply the tape with you pinkie and then peal the tape off not to fast and no to slow then put the tape on a white or black piece of paper depending on the color of powder.
