Mock Police Investigative Interview: Hospital Assault Case Study
This paper presents a hypothetical investigative interview conducted by a Queensland Police Service constable with a registered nurse who witnessed an alleged assault on a colleague at the Central Queensland Hospital and Health Service. The suspect, a combat veteran diagnosed with PTSD, allegedly struck a nurse and destroyed a computer monitor after learning his prescription medication had been changed without prior notification. The interview demonstrates proper police interview procedure, including rights advisement, open-ended questioning, and witness rapport-building. It also explores contextual factors such as PTSD, medication management, and the challenges healthcare workers face when treating traumatized veterans.

What makes this paper effective
- The script format presents a realistic, step-by-step model of witness interview procedure, making abstract policing concepts concrete and observable.
- The interviewer uses a skillful blend of open-ended prompts ("Tell me in your own words") and targeted follow-up questions, demonstrating best-practice interview technique throughout.
- Contextual details about PTSD, traumatic brain injury, and medication management are naturally embedded in the dialogue, enriching the scenario without requiring separate exposition.
- The paper humanizes both the suspect and the victim, avoiding reductive characterizations while still maintaining the procedural objectivity expected of a police interview.
Key academic technique demonstrated
The paper demonstrates applied scenario construction — building a realistic, multi-layered fact pattern and then working through it systematically using a structured interview framework. The technique shows how legal rights advisement, witness rapport, chronological narrative elicitation, and behavioral observation all function together within a single investigative encounter.
Structure breakdown
The paper opens with a stated purpose and detailed case background, followed by suspect and victim profiles. The body consists of a full interview transcript divided naturally into: rights advisement and introductions; prior incident history; the assault narrative; post-incident actions and reporting; and a closing discussion of motivating factors. The conclusion captures the witness's humanizing final remarks and the interviewer's procedural close-out steps.
Purpose and Case Background
The purpose of this mock investigative interview is to present the results of a hypothetical interview with a witness to an alleged physical assault on a registered nurse, "Martha," at the Central Queensland Hospital and Health Service, a tertiary medical center, on 30 July 2020 at approximately 0933 hours.
It has been alleged that the suspect walked into an office at the hospital and became extremely agitated, at which point he struck a registered nurse in the face with his fist, then picked up the computer monitor from her desk and smashed it against a wall. The estimated cost of the destroyed computer monitor was $200. No other patients or visitors were involved in the incident.
The registered nurse who was the victim of the assault works in the Community Mental Health Service and specializes in the treatment of adults suffering from post-traumatic stress disorder (PTSD), with a special emphasis on helping disabled Australian combat veterans who served during Operation Slipper (late 2014) and Operation Highroad (early 2015) in Afghanistan as members of the Australian Defence Force.
Suspect and Victim Profiles
The veteran suspected of the assault is a married, 50-year-old male combat veteran, "Benjamin Johnson," who served in Afghanistan from January 2014 through February 2015. During his combat tour, Benjamin suffered a severe traumatic brain injury (STBI) as a direct result of an improvised explosive device explosion that also injured several other troops in his vehicle. In addition to the STBI, Mr. Johnson suffered a broken mandible, a lacerated pancreas, two broken ankles, and a fractured right femur. To date, Mr. Johnson has undergone 17 orthopedic procedures and is currently walking with a normal gait, appearing fully recovered physically from his service-connected injuries.
During his military service, Mr. Johnson rose to the rank of staff sergeant and was ultimately assigned to lead a platoon of Australian Army soldiers prior to his injury and discharge. Following his initial treatment in Afghanistan, Mr. Johnson was returned to Australia for follow-up medical treatment and rehabilitation. After a two-month inpatient stay, he was discharged from the military and returned to civilian life in Queensland, where he remains married and employed as a machinist. Mr. and Mrs. Johnson have two adult children who live nearby but do not visit regularly.
The hypothetical interview that follows was conducted on September 10, 2020, at 1000 hours by Constable [Instructor] at an interview office at the Queensland Police Service. This case was assigned to the constable to investigate the alleged assault on Martha. The interviewee, "Jennifer," is another registered nurse who works with Martha, witnessed the alleged assault, and agreed to provide a detailed account of the incident.
