The prosecution in a criminal case relies on witnesses, including law enforcement officers, civilians, and scientific experts, to prove the defendant’s guilt. Evidence in the form of documents, tangible items, or witness testimony is presented to the judge or jury. The defendant has the opportunity to cross-examine prosecution witnesses.
In a criminal case, the state or federal government will often depend on a prosecution witness to prove its case. A prosecution witness is often a law enforcement officer, but can also be a civilian. Civilian witnesses may include a crime victim, an expert witness, a confidential informant, or a bystander who witnessed the crime when it occurred.
During a criminal trial, the prosecution must present its case to the judge or jury and convince them that the defendant committed the crime. Evidence may be admitted as part of the prosecution’s case. Evidence can be in the form of documents, tangible evidence, or witness testimony.
A law enforcement officer is almost always included as a prosecution witness. The law enforcement officer can testify to what information was gathered during the investigation of the crime or what the officer personally observed. In addition, testimony may be offered regarding any statements made by the defendant to the officer after the arrest.
Even confidential informants are considered prosecution witnesses. In many cases involving drug trafficking, a confidential informant is used to provide information or even make law enforcement purchases from suspected traffickers. If the case goes to trial, the confidential informant will have to testify against the defendant.
The victim of a crime, as well as bystanders, are often excellent witnesses for the prosecution. As a rule, their testimony is considered highly credible and may be the most detailed evidence available. A victim will also often testify at a sentencing hearing to express how the crime affected her emotionally.
Criminal trials often use scientific evidence to convict a defendant. DNA results, blood spatter, ballistics and fingerprint analysis are just some of the possible types of scientific evidence admitted in criminal trials. For a jury to understand the process of analyzing and reaching conclusions based on scientific evidence, the prosecution may hire expert witness testimony. This type of prosecution witness is responsible for explaining the results of highly scientific tests in a way that allows the jury to understand the implications of the findings.
While a person may be named as a witness for the prosecution, the defendant will also have the opportunity to cross-examine the witness. The defendant may be able to establish that the witness is biased or that the testimony you gave was inconsistent. In some cases, a prosecution witness ends up being more beneficial to the defense.
