TBI says the alleged conduct occurred in December 2024, but the state investigation did not begin until June 2026. The unanswered question is not what investigators ultimately charged — it is when police or prosecutors first learned there was something to investigate.

KNOXVILLE, Tenn. — A former Knoxville police officer has been indicted on a felony charge after state investigators said he exposed and inappropriately touched part of a deceased woman’s body while responding to a death scene.
The Tennessee Bureau of Investigation says the alleged conduct occurred in December 2024.
TBI did not begin its investigation until June 2026, at the request of Knox County District Attorney General Charme Allen. A Knox County grand jury indicted former Officer Shigeki Nagamoto on one count of abuse of a corpse Aug. 26, and he surrendered that evening before being booked on a $10,000 bond.
The charge is an allegation, not a finding of guilt. Nagamoto is presumed innocent unless convicted.
But the dates create a separate public-accountability question.
Approximately 18 months passed between the alleged conduct and the beginning of the TBI investigation.
The public record does not yet explain why.
KPD acted by June
Nagamoto was still a Knoxville Police Department officer when the state investigation began.
Knox News previously reported that Chief Paul Noel ordered Nagamoto to surrender his weapon and police equipment June 22 and reassigned him to administrative duties after the department learned of the TBI investigation. KPD’s Office of Professional Standards also opened an internal investigation. Nagamoto resigned July 4.
Those actions show what KPD did after the criminal investigation became known.
They do not answer when the underlying allegation first surfaced.
The essential chronology remains missing: Who first reported the alleged conduct? When did that happen? Was it reported immediately after the December 2024 death scene, months later or only shortly before Allen requested the TBI investigation?
Those scenarios would tell very different stories.
A body-camera question belongs near the top
Death-scene responses typically create records.
There may be dispatch logs, incident reports, supplemental reports, supervisory reviews and body-worn-camera files. The existence and content of any particular recording in this case have not been publicly established.
That makes the preservation timeline important.
Was Nagamoto wearing a body camera at the scene? Did another officer’s camera capture the relevant area? How long would the footage ordinarily have been retained? Was it flagged for preservation before any normal deletion date?
If a recording helped trigger the investigation, the public should know when it was reviewed.
If no recording exists, KPD should be able to explain the applicable retention policy without disclosing intimate images of a deceased person.
Resignation does not end the administrative question
Nagamoto’s July 4 resignation ended his employment.
It did not erase the need to determine whether departmental policy was violated or whether a supervisory or systems failure occurred.
KPD should explain whether its Office of Professional Standards investigation continued after the resignation and whether it will reach administrative findings that can legally be released. It also should identify the policies governing conduct at death scenes, respect for deceased persons, body-camera use and supervisory review.
Those issues extend beyond one defendant.
Officers routinely encounter people at their most vulnerable — during deaths, overdoses, crashes and medical emergencies. The public entrusts law enforcement with unusual access to bodies, homes and private family moments that cannot be recreated later.
That makes professional rules at a death scene more than a matter of etiquette.
They are part of the trust that accompanies the badge.
The missing 18 months should not be filled with speculation
An 18-month gap can look suspicious.
It can also have an ordinary explanation.
The alleged conduct may not have been discovered until much later. A witness may have come forward. A recording may have been reviewed for another reason. Information may have reached prosecutors long after the original response.
Without records or on-the-record sources, none of those explanations should be presented as fact.
That is why the next reporting should focus on the first report.
When did KPD learn?
When did the district attorney learn?
What caused Allen to request TBI in June?
The state investigation moved relatively quickly after that point. TBI began work in June, and the grand jury returned an indictment roughly two months later.
The unexplained period is the time before that.
Nagamoto will answer the criminal allegation in court.
KPD and prosecutors have a different question to answer publicly:
What happened between the December 2024 death scene and the June 2026 investigation?
