Blood in Crime Scene Investigation
At the scene of any violent crime, the examining officer will likely see blood and traces of other bodily fluids. These can tell a great deal about what happened, not only regarding how the crime was committed, but also about the people involved.
Nearly everybody knows his or her basic blood type, 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 samples of blood and separated the red cells from the liquid, which is called the serum. He managed this by spinning the blood at high speed in a centrifuge. Then he took the serum and added red cells from different people. They acted in two different ways: either the cells mixed with the serum, or they clumped together (clotted), (”agglutinated”).
A number of attempts at blood transfusion had been made in the past, but this observation explained for the first time why so many had failed. If introduced blood was not of precisely the same type as that in the body, it resulted in the clumping of red cells, and the patient died. Quick 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 contain substances called antigens. Antigens help make antibodies that fight infection and disease. Landsteiner suggested that his experiment showed the presence of two specific antigens, which he labelled A and B. The discovery of these antigens allowed 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 particular blood group of each person depends on the genetic inheritance from both parents. Known as ABO typing, it has been used, for example, to identify the biological father in paternity cases. How common each group is can vary 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, labelling 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 investigated. Since then, other researchers have introduced more than a dozen additional 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 an excellent means to uncover important evidence in a forensic investigation. If, for example, a victim’s ABO type is 0, and bloodstains of this type are found on the clothing of a suspect whose type is A, there is a likelihood that they have come from the victim.
Making use of the many other blood typing systems now available, this probability can be greatly increased. If blood of type O occurs in 43 percent of the population, the substance haptoglobin-2 in 36 percent of these, and the enzyme PGM-2 in five percent, then the probability of an individual having these three blood types together is 43 x 36 x 5 = 7,740 in 1 million. In other words, around 8 people in every 1,000 will have this specific type of blood. It’s still not enough to obtain a conviction on this evidence alone, but it can help to reduce the group of suspects.
In 1925, another valuable 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, in particular 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 experienced 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 result from the pumping action of the heart. A major artery can spray blood a considerable distance.
Pools of blood form around the body of the 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 if this happens. 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!
If the legal 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 a solid growth of clients, you will need to create content.
Content is an essential dynamic 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 need to make the best of the writing that you manage to produce. Following are some ideas for making sure you use two of the most commonly produced types of legal marketing content as best you can.
Law Firm Marketing - Written material (blogs, email alerts, brochures, guides, information sheets)
If you’ve created some worthwhile, interesting material in any of the types mentioned, you don’t need to only send it out once or print it and leave it to sit in your reception. You ought to distribute the content as much as possible. For every item of writing you produce, consider:
- Have I distributed it to as many, relevant, clients as possible?
- Is it loaded onto my website?
- Have I emailed it directly to referrers, associates and other professionals?
- Have I linked 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 could they explain it in detail if a client asks about it?
- Can I turn it into a different type of content and distribute in a different format?
Law Firm Marketing - Presentations
Presentations are generally created with a particular audience in mind, or because of a particular request. As a result they are often presented only once then left to stagnate. All of that time required to prepare them gets just one showing. To get more benefit from your presentation consider:
- Who else could I show it to?
- How can I let the greatest number of people know about it?
- Have I mentioned it on our website, Facebook, Twitter, and offered to present it to others?
- Is it relevant to send the presentation in hard copy to people who couldn’t 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 who were at the presentation?
While these suggestions might feel like more work at a time when you’ve probably damaged your monthly billings with the amount of time you spent preparing the first lot of material, it’s necessary to remember that it is much easier to add a tiny amount of time now to really maximise on what you’ve already produced than it is to produced a completely new piece of legal marketing material.
Increase the benefits of the time and effort you put into law firm marketing and you’ll see that the next time you need to create content you’ll feel more confident about how effective the results will be.

They are the most introverted of the types.
Sexual/ Intimate Instinct.
People of this type have a strong desire for intensity of experience and affection. The honest riveting gaze is the dead giveaway. When they enter a room they gravitate toward people they feel magnetized to, as if they are looking for the juice. These people can turn into intimacy addicts, often neglecting pressing matters or even basic maintenance if they are swept up in something that has captivated them. This gives a wide ranging exploratory philosophy to life, but can also give a lack of focus on one’s own achievements.
Social Instinct.
People of this variation are focused on their interactions with other people and with the sense of value and esteem they derive from their participation in collective activities. These include work, family, hobbies and clubs.
Upon entering a room, these people would immediately be aware of the power structures and subtle politics between different people and social circles. They are subconsciously attuned on other people’s reaction to them, particularly about whether they are being accepted or not.
They need to connect with others to feel safe, acknowledged and energised. They tend to live for interacting with others, but they eschew intimacy.
They are the most extroverted of the types.

The Importance of Proofing Designs
You’ve decided it’s time for a new site or image. For most, the first step is to choose the right company. However, the first thing you need to do is develop at least a vague idea of what you expect from the completed product. Not only is this step commonly overlooked in the starting phase of project development, but also during the creative briefing phase after hiring a design company.
Everyone wants to dump off a concept to the professionals and let them handle it all. If you’re having your car washed, then nothing is really needed from you. For other projects, you need to be more involved. Website design and graphic design are two fields where getting involved yourself is necessary to the ideal design for you and your business.
When you first meet with a website and graphic design firm, you should provide them with your estimations and goals. This provides the company something of a starting point. This doesn’t mean you are finished. No one is a mind reader. In order to make absolutely certain you get the most optimal design possible, you must take the creative briefing stage extremely.
This is the stage of the assignment where you work one on one with the designers to ensure they fully comprehend what you want. The more they understand, the faster they 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.

Choosing a Mackay Lawyer, Solicitor or Law Firm
Because it is a popular region, there are many new residents in the Mackay region who need to choose a Mackay lawyer or law firm for the first time. Finding a law firm to complete the legal work to enable you to purchase a house or building, to advise you about starting a business or to prepare legal documents like wills or enduring powers-of-attorney, can be a daunting and worrying process.
When you are trying to choose a Mackay solicitor, lawyer or law firm you should consider looking for these characteristics:
Happy Customers
For most individuals it’s 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 various law firms. What you can do is look for a Mackay solicitor who is proud of their past performance provides testimonials from previous or existing clients. If they provide quite a number of testimonials it tells you two things. Firstly, that they have plenty of happy clients and secondly, that they are willing to take time and go to the trouble to discover what clients think of their service. They understand that theirs is a service-oriented business.
Local knowledge
Any Mackay lawyer or solicitor ought to have a good local knowledge and demonstrated experience in assisting other people in the town. Look for firms that have 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 that can make a big difference to the way your transaction will be dealt with.
Breadth of Services
While most people only need a lawyer rarely, it is wise to choose a Mackay lawyer, solicitor or law firm which can provide a full range of services without having to find additional providers. Finding a firm that can assist with your conveyancing, estate planning, disputes, business services and even workplace or employment issues, means you can rely on the one firm that will meet all your legal needs. Law firms value clients who use several services, and will often provide those services more cheaply and efficiently when they have done 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.
