Circumstantial evidence

CROSS-EXAMINATION EXPERIENCE OF CHILD WITNESSES Zajac, Irvine, Ingram and Jack indicated that cross-examination coerced child witnesses into indiscriminately changing their initial correct and incorrect responses. Their empirical evidence also suggested that cross-examination questioning is detrimental to the accuracy of child witnesses, and children with low assertiveness and low self-confidence are more adversely affected through being challenged about their credibility by cross-examiners.…

decedent is touched or moved, there is a significant possibility that valuable evidence could be lost or contaminated.

Because the officer touched the revolver with his bare hands, he contaminated the evidence by possibly leaving his hairs, fibers and or fingerprints. At that time,…

They collect important physical evidence that they can find like fingerprints, footprints, and trace materials, any hair that hadn’t been burnt and fibre from the clothes of the women or on the car seats.

largely upon nine (9) purported intercepted calls, which if proven false would not subject either brother to an indictment or to Michigan’s jurisdiction. The record lacks any evidence to prove that the lawyers filed several motions important to the outcome of the case. They did not file a Frank’s motion, a Motion to Suppress Evidence of Illegal Wiretapping under Title III and there is no motion under 901, 704 or 701 that could identify the voice or establish the identity of the parties to the…

Bloodstains can be key evidence to a crime because the patterns can be as unique as finger prints by giving direction, height and angel of the blood spatter. Since no one in the world has the same DNA you could figure out exactly who the blood came from and if you know where the killer or victim was you could triangulate the position of the crime. It also can give you a time frame for the crime by the way the blood coagulates and dries. There are three types of bloodstains passive stains,…

documenting of evidence from the initial discovery, in situ, up it is used in the courtroom. Through each step of the process: labeling, collecting, preserving, transferring, and analyzing,each piece of evidence, including locations and all those involved in handling the materials are systematically logged.
