CCJS 342: Crime Scene Investigation

CCJS 342 at the University of Maryland Global Campus focuses on the crime scene itself: how it is secured, recorded, searched and processed, and what follows once the scene is released.

UMGC's catalog describes an examination of crime scene investigation aimed at the skills expected of an entry-level professional in investigative forensics. The listed topics are the crime scene, crime scene documentation, evidence and post-crime scene activities. The prerequisite is CCJS 100, CCJS 101 or CCJS 105.

It is one of six required courses in UMGC's undergraduate Crime Scene Investigation certificate. Students often find that the hardest part is not knowing the steps but writing them up precisely enough that another investigator could follow them.

What CCJS 342 Covers

• The crime scene: first response, securing the perimeter, preventing contamination and controlling who enters.
• Documentation: notes, photographs and sketches, each with its own purpose and standards.
• Evidence: search patterns, recognition, collection and packaging of physical evidence.
• Post-crime scene activities: submitting evidence to the lab, follow-up, reports and preparing to testify.

Key Concepts Explained

The Three Forms of Documentation

Notes record what was done and observed, in time order. Photographs show the scene from overall to close-up views. Sketches give measured positions that photos alone cannot. Good scene work uses all three, and each supports the others.

Search Patterns

Line, grid, spiral and zone searches suit different spaces. The right answer depends on the scene's size, terrain and number of searchers.

Releasing the Scene

Once released, a scene cannot usually be re-entered without new legal authority, so a final walk-through matters.

Typical Assignments and How to Approach Them

Writing the Scene Report

Scene reports in CCJS 342 are judged on whether someone who was not there could understand what happened at the scene and in what order. Write in the past tense and the first person or passive voice your instructor prefers, and keep opinions out of the narrative.

A clear layout:

• Summary: date, time, location, case number and your role.
• Arrival and security: who was present, the perimeter and the entry log.
• Scene description: general to specific, matching the order of your photographs.
• Evidence: a numbered list with location, collection method and packaging.
• Release and follow-up: final walk-through, time released and lab submissions.

Cross-reference everything. If the report says item 4 was a cartridge case under the window, the photo log, sketch and evidence list should all agree on item 4. Inconsistent numbering is one of the easiest errors to make and one of the easiest for a marker to spot.

The Legal Side of Scene Work

Scene processing does not happen in a legal vacuum. Entering and searching a scene may need consent, an emergency justification or a warrant, depending on the circumstances and the jurisdiction. Once the emergency ends, investigators usually need legal authority to continue searching.

In assignments, a short note on legal authority at the start of your processing plan shows you understand that well-collected evidence can still be excluded if the search itself was unlawful. Your criminal procedure notes from CCJS 234 are useful here.

Where Students Get Stuck

• Skipping scene security. Contamination control comes before evidence collection.
• Photos without a plan. Overall, mid-range and close-up views are all expected.
• Sketches without measurements. A sketch must let someone relocate each item.
• Forgetting the aftermath. Lab submission and reporting are part of the investigation.

Study Tips for CCJS 342

• Practice sketching a room at home with measurements from two fixed points.
• Write a checklist from arrival to release and test it against each scenario.
• Use past tense and objective language in notes and reports.
• Connect each step to how it would be challenged in court.
