o these in an immovable ———— casing with a warning label that a sharp object is enclosed.

Answer 1

First, Petra photographs and measures the mark, then makes a replica of the hole. She collects all the knives in the area for comparison and uses them to create additional replicas of the marking. She then carefully documents the chain of custody for each of the replicas, ensuring that they are stored securely and remain unaltered until they can be analyzed by a forensic expert. When packaging the knives, Petra uses airtight and tamper-proof containers, such as evidence bags or boxes, to prevent contamination or damage to the evidence. Each container should be clearly labeled with identifying information, such as the location, date and time of collection, and the names of those who collected and handled the evidence. It is important that Petra takes great care to preserve the integrity of the evidence and follow proper chain of custody procedures to ensure that the evidence can be used in court, if necessary.
