Blood in Crime Scene Investigation
At the scene of any violent crime, the examining officer will likely discover blood and evidence of other bodily fluids. These can tell a lot about what occurred, not only regarding details of how the crime was committed, but also about the people involved.
Nearly everybody knows his or her basic blood type, and whether it is A, B, AB, or 0, and Rhesus negative or positive. This categorising of blood into types was first done by Austrian physiologist Karl Landsteiner at the end of the 19th century. In his experiments, he took small amounts of blood and separated the red cells from the liquid, which is called serum. He did this by spinning the blood at high speed in a centrifuge. Then he took the serum and added red cells from different people. They responded in two different ways: either the cells mixed with the serum, or they clumped together (clotted), which is called ‘agglutination’.
Numerous attempts at blood transfusion had been made in the past, but this observation explained for the first time why a great proportion had failed. When the blood was not of precisely the same type as that in the body, it produced the clumping of red cells, and the patient died. Tests of blood samples to discover whether agglutination will occur is now done prior to a transfusion being made.
DIVIDING BLOOD INTO GROUPS
Red blood cells carry substances called antigens. These help make antibodies that fight infection and disease. Landsteiner believed that his experiment showed the presence of two specific antigens, which he labeled A and B. The discovery of these antigens enabled him to divide human blood into 4 basic groups:
Group A: antigen A present; antigen B absent
Group B: antigen A absent; antigen B present
Group AB: both antigens A and B present
Group 0: both antigens absent
The specific blood group of an individual depends on the genetic inheritance from both parents. Known as ABO typing, it has been used, for example, to help identify the biological father in paternity cases. How common each group is varies from one national population to another. In the United States, for example, the relative proportions of ABO groups are roughly 39 percent A, 13 percent B, 43 percent 0, and 5 percent AB.
In 1927, Landsteiner discovered two other antigen types, labeling their occurrence as M, N, and MN. In 1940, working in the United States, he and A.S. Wiener discovered the Rhesus factor, named after the Rhesus monkeys they used in their investigations. Since then, other researchers have introduced more than a dozen further group systems. Different proteins and enzymes associated with specific blood groups have also been identified.
WHAT THIS MEANS FOR FORENSICS
The ability to identify blood type is a powerful means to reveal important evidence in a forensic investigation. If, for example, a victim’s ABO type is O, and bloodstains of this type are discovered on the clothing of a suspect whose type is A, there is a likely probability that they have come from the victim.
Making use of the many other blood type systems now available, this probability is increased greatly. If blood of type O occurs in 43% of the population, the substance haptoglobin-2 in 36 percent of these, and the enzyme PGM-2 in 5%, then the probability of an individual having these three blood types together is 43 x 36 x 5 = 7,740 in 1,000,000. In other words, around 8 people in every thousand have this specific type of blood. It is still insufficient to obtain a conviction on this evidence alone, but it can help to reduce the group of suspects.
In 1925, another important discovery occurred. Around 80 percent of humans are ’secretors’. This means their saliva, urine, perspiration, and semen contain the same substances as their blood, and are able to be used for typing in a similar way. In 1940, two British researchers discovered it was possible to distinguish between female and male body cells, especially the white blood cells and those of the lining of the mouth. Blood typing has now become so precise that recently one scientist showed that he could distinguish between the blood of his twin daughters, who were genetically identical, because one had had chicken pox and the other had not.
SPLASHES OF BLOOD
At the scene of a violent homicidal attack, blood may be present in considerable quantities. Not only will it be found on the victim, but also on the weapon and the surroundings. Indoors, the floors, walls, and even the ceilings may be splashed. Careful observation of these bloodstains can provide valuable clues about what took place. Bloodstains and splashes are classified into six basic types.
Round drops are found on horizontal surfaces; depending on the height from which they fell, they can spray out into a starlike shape. Splashes of blood are shaped like an exclamation mark; they show that blood has flown through the air and hit a surface at an angle. While a victim is still alive, spurts of blood come from the pumping action of the heart. A major artery can spray blood a considerable distance.
Pools form around the body of a bleeding victim. If there is more than one pool, he either crawled, or was dragged, from one spot to another before dying. Smears are likely also found in this case. Trails are left when a bloody corpse is moved. There will be drops found if the body was carried, and smears if it was dragged.

Law firm marketing: Making the most of what you’ve got!
Whether the marketing strategy for your law firm is based on online marketing, niche marketing to particular industries, traditional advertising, or just retaining and growing a share of your stable of clients, you’ll need to create content.
Content is the lifeblood of legal marketing, and without it you might just as well not bother with a law firm marketing plan. But producing content is hard work, and you should make the most of the material that you can produce. Here are just a few suggestions to help you use two of the most commonly produced types of legal marketing content as effectively as you can.
Law Firm Marketing - Written material (blogs, email alerts, brochures, guides, information sheets)
If you’ve produced any worthwhile, interesting material of any of the formats above, don’t only send it off once or print it and let it sit in your reception. Distribute the content as broadly as is possible. For every piece of writing you produce, consider:
- Have I sent it to as many, relevant, clients as I can?
- Has it been loaded onto our website?
- Have I sent it directly to people who have referred me, associates and other professionals?
- Have I linked to it with a post on Facebook and a tweet on Twitter?
- Has it been sent to media contacts?
- Are others in the firm aware of it and can they explain it in detail if a client questions them?
- Can I turn it into a different type of content and distribute in a different forum?
Law Firm Marketing - Presentations
Presentations are usually created with a particular reception in mind, or because of a particular request. Therefore they are often presented only once and then left to become stale. All of that effort and time required to prepare them results in only a one time presentation. To get more benefit from your presentation consider:
- What other companies can I show it to?
- How can I let the most people know about it?
- Have I mentioned it on my website, Facebook, Twitter, or offered to present it to others?
- Is it relevant to send the presentation in hard copy to people who were unable to attend the seminar?
- Can I record an audio or video of the presentation and distribute it electronically online or directly?
- Is it viable to write an article or blog discussing topics that arose during the presentation?
- Have I sent additional content to all the people that attended the presentation?
Although a lot of these suggestions may feel like additional work just when you’ve possibly created a dent in your monthly billings with the amount of time you spent preparing the first lot of material, it’s crucial to remember that it is far easier to add a small amount of time now to really impact on what you’ve already produced than it is to produced a completely new piece of legal marketing material.
Increase the results of all the time and effort you put into law firm marketing and you’ll find that the next time you need to create some content you will feel more confident about how effective that content will be.

Social Instinct.

Sphere: Related ContentThe Importance of Proofing Designs
You’ve concluded it’s time for a new site or design. For most, the first step is to choose the right company. However, the first thing you should do is develop at least a vague concept of what you expect from a completed product. Not only is this step commonly overlooked in the starting phase of project development, but also during the creative briefing stage after recruiting a design company.
Everyone wants to send off a concept to the professionals and let them take care of everything. If you’re having your car washed, then nothing is really required of you. For design briefs, you need to be more involved. Website design and graphic design are two areas where getting involved yourself is essential to the perfect design for you and your business.
During your first meeting with a website and graphic design agency, you should provide them with your ideas and goals. This provides the company with a starting point. This doesn’t mean you are done. No one can read your mind. In order to be certain you get the best design possible, you must take the creative briefing stage seriously.
This is the part of the project where you work one on one with the designers to ensure they fully understand what you want. The more they understand, the quicker that can deliver the finished project. It also reduces the number of initial design changes.
The next step before the designer can work on your project is proofing your design. You should never just quickly glimpse the design and give your approval. Look over the design plans as thoroughly as you would any important document. If the design isn’t exactly as you envisioned it and doesn’t provide the features you discussed, now is the time to make changes.
Waiting until the final project is delivered means time consuming revisions for both you and the designer. By involving yourself in both the creative briefing and design proofing stages, you save both time and money. You also get the perfect website or graphic design the first time around. The sooner your project is in place, the sooner your customers and visitors will see it.
You should never take this responsibility lightly. It’s your design, your website. Take the time to ensure the design company you choose fully understands your vision. By communicating your needs, the company is able to provide suggestions. With thorough communication between both parties, the best designs and sites are created.

Sphere: Related ContentChoosing a Mackay Lawyer, Solicitor or Law Firm
Because it is a growing town, there are many new families and people now living in the Mackay region that are choosing a Mackay lawyer*, solicitor or law firm for the first time. Finding a law firm to do the legal work required to help you buy a house or building, to give advice about starting a business or to prepare important documents such as wills or enduring powers-of-attorney, can be a intimidating and worrying process.
When you are needing a Mackay solicitor, lawyer or law firm you ought to consider looking for these attributes:
Happy customers
For most individuals it is impossible to compare the quality of legal services that is provided by one Mackay solicitor/lawyer or another. Unless you regularly use the same sort of legal service you can’t really compare different law firms. But you can look for a Mackay solicitor who is proud of their past performance provides testimonials from previous or existing clients. If they offer plenty of testimonials it tells you two things. First, that they have numerous happy clients and secondly, that they take the time and trouble to find out what clients think of their service. They are aware that they are a service-oriented business.
Local Knowledge
Any Mackay solicitor or lawyer should have good local knowledge and demonstrated experience in helping other people in the area. Find out if the firm has worked on local developments or firms with established conveyancing sections that have built up a valuable source of “inside knowledge” about the property market, local agents and banks which can make all the difference to the way your transaction will be dealt with.
Breadth of services
Because most people only need a lawyer rarely, it is wise to find a Mackay solicitor, lawyer or law firm that can provide a full range of services without having to seek other law firms. Finding a firm that can provide conveyancing, estate planning, disputes, business services and even workplace or employment issues, means you can stick with the one firm to meet all your legal requirements. Law firms value clients who use several services, and will often provide those services more cheaply and efficiently when they have provided other work for you in the past.
*In Queensland a person with legal qualifications was traditionally referred to as a solicitor while a person who “had standing” to represent you in court was called a barrister. More recently the general term lawyer has become more widespread and can be used to describe either of these types of legal practitioner. In some other states of Australia the conveyancing process (the legal process required to transfer ownership of house) can be undertaken by licenced conveyancers. This is not the case in Queensland where conveyancing must be undertaken by a solicitor/lawyer.
