Crime Investigation Case

Crime Investigation Case

Fisher and Fisher (2012) argue that cases of manual strangulation and sexual assault are rampant and shared in areas of residence. The incidences mostly result from malicious activities, usually perpetrated by ill minded people. It takes a good procedure and course of action to combat the malpractices and finally bring the involved individuals to book and perhaps put them behind bars to face the responsibility for their actions. For the case in question, it is proper that we critically scrutinize the evidence and location of crime to reach a conclusion and make a sound decision.

Evidence samples from the scene

In the case at hand, the primary evidence and samples to collect in the aid of investigation may include the trace evidence that includes the tiny pieces of proof in the crime scene. In this case, the trace evidence includes the fragments of cut grass (Christian, Lavelle, De Jong, Loiselle, Brenner & Joffe, 2000). The elements are vital in showing the relative movement of the victim or the criminal during the time of the crime. (Resick & Schnicke, 2002)

The next piece of evidence will be the T-shirt, handbag, and purse. According to Christian, Lavelle, De Jong, Loiselle, Brenner & Joffe (2000) the phenomena too, are critical in the determination of any contact between the victim and the potential criminal. It is vital to note that the purse and handbag could be carrying forensic evidence, usually invisible to the naked eye, but essential in the crime detection criteria. The evidence that could be transported in the bag and purse is mostly the criminal’s fingerprints (Christian et al., 2000).

It is also important to take the general photograph of the crime scene as a piece of evidence. Also, an explicit picture of the woman lying on the ground is essential. The photos show relative motion of the crime activity, from the initial to the final stage. For instance, the drag marks in the grass could provide a vital clue to the course of the crime (Christian et al., 2000).

Merits and demerits and attending scene discovery

Resick and Schnicke (2002) asserts that visiting the crime scene could both be advantageous and disadvantageous. On the practical side, the investigative officers are in a good position to notice pieces of evidence that could disappear with time. For example, the drag marks, if left for a couple of hours, could go. The scenario leads to the loss of driving hints to the course of the crime process. Such clues are useful in the determination of the likely criminal, considering the possible path before the offense happened (Fisher & Fisher, 2012).

It is also advisable to attend the crime scene to rescue the victim if they show any signs of life. Resick and Schnicke (2002) explains that it is possible that the victims may appear dead but possess some traces of life. In the case of presence of an investigation officer or any medical personnel, immediate help can be arrived at, leading to saving of life (Fisher & Fisher, 2012). The officer present can probably call the ambulance and have the patient taken to a health institution if they show signs of life.

Also, the presence at a scene of a crime can lead to the protection of the evidence present at the time of occurrence. An officer present can detect any threats to the pieces of evidence and possibly deter the interference of proof (Fisher & Fisher, 2012). Consequently, the individuals can secure the area by taping its environs to prevent entry of naive persons or people with malicious intentions (Resick and Schnicke, 2002). Doing so helps in the preservation of evidence until the time it is needed.

On the contrary, it is disadvantageous to attend the crime scene for one prime reason. The primary reason for not attending the scene is that it may lead to the distortion of the evidence available at the felony location (Resick and Schnicke, 2002). Such pieces may include forensic evidence such as fingerprints and hair follicles that may contain DNA information concerning the possible criminal. I, however, opine that the investigation officials be present at the location of crime occurrence to save lives if any and protect the area to help keep the pieces of evidence intact.

Forensic science samples from a pathologist

Notably, the police work hand in hand with the forensic scientists and forensic pathologists in the investigation of crime (Christian et al., 2000). In the case at hand, several pieces of evidence will be required to determine the occurrence of sexual assault. First and foremost, the purse and handbag will be vital in this case. Turning to Resick and Schnicke (2002), one finds that the bag could provide leading information to the coroner concerning the probable criminal. Together with the handbag, the elements may contain forensic evidence, fingerprints to be precise that could aid in the determination of the criminal. According to Christian et al., (2000), any foreign fingerprints give essential clues to the possible criminal.

Also, the blood samples from the woman’s nose, mouth, arm, and breast may give vital hints in the crime investigation. Because the scene showed minimal signs of violence, the blood test may be of so much use. The fluid may lead to the discovery of foreign DNA that could give useful leads to suspects and finally the criminal (Christian et al., 2000).

Also, the body of the woman can get scanned to unearth different fingerprints if any. The occurrence of foreign fingerprints on the body shows the presence of a person or persons during the time of crime incident. Further scrutiny of the prints leads to revealing of the responsible individuals who may be taken as suspects. Crucial interrogations can then start to help identify the real criminal (Christian et al., 2000).

Control samples

The control samples, in the given case, include blood and urine samples to help determine if intoxication could have been the cause of the woman’s death. Scientifically, the urinary and blood alcohol content disclosed in the autopsy reveals that the woman might have been intoxicated (Resick and Schnicke, 2002). As stated by Christian et al., (2000), the use of control samples in the determination of toxicology level could be useful in helping reach a sound decision.

In a nutshell, the crime resolution can sometimes be wanting, especially if it brings so many options in the circle. In cases of manual strangulation and sexual assault, the use of forensic evidence such as DNA and fingerprint samples can help disclose possible suspects and eventually criminals. However, the presence of investigative officials at the crime scene is highly recommended to help guard the scene and assist the victims in any possible way. The coordination between the police spearheading the inquiry and the forensic pathologists is the key to success in such cases.
