Recorded interview transcript
LEAD INVESTIGATOR: State your full name for the record.
LEWIS MARSH: Lewis Marsh
LEAD INVESTIGATOR: Do you understand the status of this interview and the limits placed on distribution?
LEWIS MARSH: I understand. My agreement to answer does not waive any objection already entered into the record.
LEAD INVESTIGATOR: Have you been offered the representation, legal advice or staff support applicable to this procedure?
LEWIS MARSH: Yes. I am proceeding under the conditions already stated.
DOCUMENTARY EXHIBIT D-01 Retained extract: A younger technician, Lewis Marsh, shifted uncomfortably. “We secured it after retrieval. Associated persons: Natalie Brooks, Derek Hastings Relevant systems or locations: black box, evidence
LEAD INVESTIGATOR: Do you accept that this extract accurately records an event in which you were involved?
LEWIS MARSH: That is broadly how I remember it. I cannot confirm the exact time from memory. Check black box against the unprocessed record before you accept the later label.
LEAD INVESTIGATOR: What did you understand at that moment, before later analysis supplied a larger explanation?
LEWIS MARSH: I am not refusing the question. I am separating what I remember from what I learned afterwards. The missing interval matters more than the wording placed around it afterwards.
DOCUMENTARY EXHIBIT D-02 Retained extract: Lewis Marsh’s flat smelled of stale air and something synthetic, like spilled medication. Associated persons: Natalie Brooks
LEAD INVESTIGATOR: Do you accept that this extract accurately records an event in which you were involved?
LEWIS MARSH: I am not refusing the question. I am separating what I remember from what I learned afterwards. Natalie Brooks can confirm the sequence, but not necessarily the interpretation.
LEAD INVESTIGATOR: Who else was physically present and capable of confirming your account without relying on the same electronic record?
LEWIS MARSH: I saw what happened. I did not know then what it meant. If the original is no longer available, that absence should remain part of your finding.
LEAD INVESTIGATOR: Are you saying the official record is wrong?
LEWIS MARSH: I am saying the record should remain evidence, not become an alibi for the system that produced it.
DOCUMENTARY EXHIBIT D-03 Retained extract: Lewis Marsh’s flat smelled of stale air and something synthetic, like spilled medication. Associated persons: Natalie Brooks
LEAD INVESTIGATOR: Do you accept that this extract accurately records an event in which you were involved?
LEWIS MARSH: That is broadly how I remember it. I cannot confirm the exact time from memory. The missing interval matters more than the wording placed around it afterwards.
LEAD INVESTIGATOR: Why was the matter not escalated through the ordinary reporting route?
LEWIS MARSH: I saw what happened. I did not know then what it meant. I will not improve my memory to make the chronology easier.
DOCUMENTARY EXHIBIT D-04 Retained extract: Marsh’s phone was locked, no notifications on the screen. Associated persons: Fiona Ward, Natalie Brooks
LEAD INVESTIGATOR: Do you accept that this extract accurately records an event in which you were involved?
LEWIS MARSH: The record may be right. I can only tell you what was in front of me. Check the physical record against the unprocessed record before you accept the later label.
LEAD INVESTIGATOR: What part of the retained record is incomplete or misleading?
LEWIS MARSH: The record may be right. I can only tell you what was in front of me. My answer is limited to what I personally saw, heard or ordered.
LEAD INVESTIGATOR: Are you saying the official record is wrong?
LEWIS MARSH: I am saying you should preserve the contradiction instead of choosing the tidier version.
DOCUMENTARY EXHIBIT D-05 Retained extract: One strike. “Lewis Marsh.” One strike.
LEAD INVESTIGATOR: Do you accept that this extract accurately records an event in which you were involved?
LEWIS MARSH: I saw what happened. I did not know then what it meant. The missing interval matters more than the wording placed around it afterwards.
LEAD INVESTIGATOR: Which physical record should be examined before this account is treated as settled?
LEWIS MARSH: That is broadly how I remember it. I cannot confirm the exact time from memory. I will not improve my memory to make the chronology easier.
[Exhibit S-01 introduced. Subject permitted to inspect the displayed copy without handling the source medium.]
LEAD INVESTIGATOR: Do you identify the person shown as yourself?
LEWIS MARSH: I identify myself in the frame. I cannot authenticate the date from the crop alone.
LEAD INVESTIGATOR: Can you establish the location or date from anything visible in the frame?
LEWIS MARSH: The location is supportable from the surroundings. The purpose you are implying is not.
LEAD INVESTIGATOR: Were you aware that the image was being made?
LEWIS MARSH: I was not aware of the camera at the time shown.
LEAD INVESTIGATOR: Who had advance knowledge of your presence at that location?
LEWIS MARSH: That depends on whether the source is an official system, a copied feed or a separate observer.
LEAD INVESTIGATOR: What does this image prove, and what does it not prove?
LEWIS MARSH: Preserve the frames before and after it. A single image is a fact about light, not a complete account of conduct.

LEAD INVESTIGATOR: Is there any material fact you have withheld because you consider this recording or its distribution unsafe?
LEWIS MARSH: No fact material to immediate safety. Other matters require a narrower compartment.
LEAD INVESTIGATOR: What is the single next action this investigation should take?
LEWIS MARSH: Find the first system that accepted an answer without asking who had authority to give it.
LEAD INVESTIGATOR: Do you wish to add or correct anything before the recording is suspended?
LEWIS MARSH: No correction. Only this: an accepted record is not necessarily a true one.
[Recording suspended. Source media sealed. Any resumed session requires a new opening declaration and exhibit schedule.]
Confidential investigator assessment
The interview produced useful corroboration points and several testable contradictions. It did not establish final responsibility for the events examined.
