“The importance of gathering evidence: To assure a successful presentation in court, leading to aconviction of the person or persons responsible for a crime. To collect evidence about the crime that would help with the investigation. Preventing the suspect from destroying any evidence, thatcould incriminate him or linking him to the crime. Hence help identify the suspect and the victim. And provide legal evidence as proof of a crime”. Lasley, J., Guskos, N., & Seymour, R., (2014). If the detective fails to gather sufficient evidence, it will not be possible to prove the crime (Lasley, J., Guskos, N., & Seymour, R., 2014). Also, if the detective fails to seize evidence properly, it will be suppressed or made unavailable. Note that suspects may destroy evidence thatcould be used to incriminate them, ensuring there is no evidence to prove or link them to the crime.

J10V CRIMINAL INVESTIGATION; A4_04 interrogation. During this interrogation, the detective should try to get the suspect to admit guilt or confess to elements of the crime. Failing to arrest the suspect could result in witness tampering, the suspect could flee (and resources would have to be spent on subsequently apprehending the suspect), and failure to obtain a witness interview (which may make it impossible to prove the case). Build a case for trial The detective must provide prosecutors with evidence to prove “beyond a reasonable doubt” that the legal requirements of a homicide have been met. The detective should also be able to demonstrate that the investigative process was conducted in a fair and just matter.
