Question

1. during a criminal case, the detective tells his team that there is a problem with the chain of custody. what does this most likely mean?

the judge did not grant a proper search warrant.
the jury will now wonder if the evidence is valid.
the expert witness lied when they were under oath.
the final sketch has the wrong dimensions.

Explanation:

Chain of custody refers to the chronological documentation or paper trail that records the sequence of custody, control, transfer, analysis, and disposition of physical or electronic evidence. If there is a problem with the chain of custody, it can cast doubt on the integrity of the evidence. This means the jury may question if the evidence is valid as they need to be sure that the evidence presented is the same as what was collected and has not been tampered with or mishandled. A problem with the chain of custody is not related to a search warrant (that's about the legality of obtaining evidence initially, not its handling after collection), an expert witness lying (which is perjury and a different issue), or a sketch's dimensions (unrelated to evidence handling and integrity).

Answer:

The jury will now wonder if the evidence is valid.
