Both courts and police investigators need to be able to understand the potential effects of a particular explosive or explosive device and to be able to set it into its proper context. For example was this a mere firework being misused by a naughty schoolboy, or a weapon of mass destruction That is not, of course, to forget that devices illegally constructed from fireworks can cause horrific injuries. 

At about midnight, an explosion is heard.Nathanael s father lies burnt and dead on the floor of his study. The incident is the subject of a police investigation, but Coppelius is nowhere to be found, and the case remains unresolved. 

Viewed collectively, the preceding chapters clearly pertain to a familiar literary genre called scholarship. Due however to certain conditions unique to this particular investigation, here specifically treated as a case, another familiar literary staple necessarily informs the operations of this narrative, the detective story. As we should all know, the basic trinity of all serious police investigation comprises the following elements 1) the perpetrators confessions, 2) corroborating statements by witnesses, and, most reliable, 3)... 

Trace Evidence. Trace evidence refers to minute, sometimes microscopic material found during the examination of a crime scene or a victim s or suspect s clothing. Trace evidence often helps police investigators develop connections between suspect and victim and the crime scene. The challenge to the forensic scientist is to locate, collect, preserve, and characterize the (race evidence.

A wide range of items of a ballistics nature have been retained over the years and a large amount of information is stored on computer. This statistical database was a valuable aid to police investigating officers, and a similar intelligence framework operated for explosives and explosive devices. 

The police investigator has a problem in trying to track down the source of the drug trade he invariably proceeds from the... 

Nonetheless, the revelation of death by poisoning sent coroners, prosecutors and police investigators scurrying to learn more about the 12 or so known cases of oleander poisoning and to obtain copies of "The Poor Man s James Bond," which is not widely available but ts stocked in some survivalist shops. 

Although the police investigation collected enough evidence to prove that sarin was used by AUM Shinrikyo terrorists in Tokyo, the final scientific proof came this summer, when two laboratories independently determined sarin metabolites in blood and urine samples drawn from Tokyo subway attack victims. The Holland group of investigators liberated them from plasma butyrylcholineste-rases [14], while the Japanese group used urine instead [30],... 

It turned out to be the murder weapon. The pocketknife the police discovered at the scene had been used by the victim in self-defense. And two knives indicated a knife fight. Was it part of a gang war The police investigated and found out that the victim was a member of a gang that was at war with another gang. By interrogating members of the rival gang, they eventually identified the murderer. 

Another case, in which the bitter taste of strychnine was to play a major role in the downfall of the murderer, is that of Lincolnshire housewife Ethel Major. The police received an anonymous letter which stated that Ethel s husband, who had died on 24 May 1934 after two days of agony, had complained that his food tasted foul and throvm it to the neighbour s dog. The dog had subsequently died and when its and Mr. Major s corpse were exhumed both were found to contain strychnine. During the police investigation, Ethel unwittingly impHcated herself when she stated that she was tmaware that her husband had "died of strychnine poisoning", before mention had been made of strychnine. She was tried in November 1934, found guilty and, despite a recommendation of... 

During the police investigation of the scene of a multiple murder at the home of the victims, a greasy substance was found on a bedroom door and a fingerprint was found on the grease. 

Guidance The CMV would not be considered involved unless the police investigation officer determines that the CMV caused or contributed to the accident. 

Once the patient has been removed and taken away for treatment the site should be isolated and nothing disturbed. An investigation should start immediately. In the event of a fatal accident, the deceased should be identified and relatives informed. There could be some religious problems in the case of Indian, Pakistani, Jewish or Roman Catholic employees, etc., and their wishes in respect of, e.g. the local priest etc. should be complied with. The police should be informed and the site, including property of the deceased, tools etc., should be left undisturbed until they arrive. The police investigation will be concerned with the cause of death rather than the cause of the accident. The HSE should also be informed and, if the death was due to gassing or poisoning, a doctor from EMAS will be involved. 

A fingerprint can often be the most important piece of evidence left behind at the scene of a crime. Police investigators use a variety of methods to visualize fingerprints. One such method involves the use of a chemical agent called ninhydrin, which reacts with the amino acids present in the fingerprint to produce colored compounds that can be seen. But what are amino acids, why are they present in our fingerprints, and what function do amino acids serve ... 

In police investigations it is often necessary to detect traces of metallic lead in certain portions of substrates which may have been exposed to the impact of uncoated lead bullets discharged from fire arms. Such substrates, whether they have been penetrated or pierced, may be of various kinds in general, wood, fabrics, and paper are to be considered. The rhodizonate test as used in the foregoing procedures can be employed. 

In a police investigation of a severe accident, the investigators will look for breaches of statutory duties and other evidence of criminal negligence or wilful criminal acts. When addressing the question of culpability, the investigation will produce defensive reactions on behalf of the individuals and the organisation concerned. These reactions will counteract openness and trust and will obstruct the learning process. 

At the same time, the authorities must be aware of the negative side-effects of police investigations. It has been proposed that the authorities law-enforcement role can be played down in cases where the company demonstrates a clear willingness to learn from the accident. This principle should also apply when there is significant new learning involved as compared to a case when the same type of accident happens again. 

The approach selected here for in-depth accident and near-accident investigation should not be confused with the police investigations of such events. It differs from the police investigations in that the latter aim to discover which laws or company procedures have been violated, who violated them and who is liable. 

Where the accident is under police investigation, the police have the right to request full access to the company s internal report. Knowledge of this fact will affect the commission s work and may hamper openness and trust. A careful balance must be kept between the need for openness, to take full advantage of the accident experience, and the involved persons legitimate right of self-protection when they face the risk of legal action.
