Help with peer responding to a classmates discussion post

The officers were allowed a warrantless entry due to the observation of blood and shell casting through the window. This was an emergency circumstance justified by a possible threat to life or safety. They were then justified in completing a sweep of the premises to locate the victim and possible suspect and preserving the crime scene. I would then secure a search warrant to begin the crime scene search, beyond what is in plain view, and collection of physical evidence.

I'll call upon CSI to process the scene and collect evidence. They'll document the crime scene by writing detailed notes in a notepad dedicated to the case, photos using a variety of angles, and a video-recorded walkthrough of the crime scene. They would be responsible for collecting physical evidence such as blood samples and the shell castings seen. All evidence found during a search should be marked and photographed before collection. They have evidence collection kits with the tools needed for evidence collection.

The shell casings must be collected, each separately bagged and clearly labeled. Not sure if the floors are hardwood or carpet. If the carpet is stained with blood, the parts of the carpet should be cut out, placed in porous packaging, and labeled. If hardwood flooring, use swaps or any absorbent pads to collect the blood. The swabs or pads should be placed in a suitable container and labeled. Fingerprinting kit should be used to obtain any fingerprints found at the scene. Collecting the husband's print to possibly exclude him could happen now or later in the investigation. All collected evidence should be logged into the Chain of Custody with the date, time, location, and name of the investigator who collected it.

I would also talk to neighbors to see if they witnessed any abnormal activity from the house, that day/night or any other day/night, as the husband has implicated a possible drug scene. Take note of any video doorbells.

The type of evidence from this scene is mostly Demonstrative evidence, with photos and videos, Real evidence with blood samples, shell casings, and prints if any found and Testimonial evidence from neighbors and husband.

Questions for my classmate?

Highlighting the chain of custody stresses the significance of keeping a precise record of how evidence is managed. This process is essential for ensuring the integrity of the evidence in court cases.
