The room, one moment at a time
The same case as the Chronological View, drawn as the room it happened in. Move the line along the bar, or step with Previous and Next, and the room changes with the moment: who was in it, who was only on a screen, and which parts of it stood empty.

The jury box
Empty: no jury in either case
Federal jury selection was set for September 8, 2026, then October 13, then January 5, 2027, and the plea of August 14 ended the need for one. The state trial set for September 8, 2026, has not begun.

The public gallery
Supporters, and the press
A few dozen supporters came, most of them women and some dressed in green. About two dozen had lined up outside to get in, one of them for thirty hours.
-
The public gallery
Not recorded
The reporting used here describes the supporters outside the courthouse and not the benches inside. His state hearings have drawn lines for seats, so these were probably not empty.
-
The public gallery
Not recorded
A minute entry lists the lawyers and says nothing about who watched. His hearings in the state court have drawn lines of supporters and a full press bench, and the same kind of crowd is likely here.

Notes
How this was made, and what it leaves out
Source
The federal case is built from its own docket, No. 1:25‑cr‑00176 (MMG), read in full through the archive of PACER filings. Every federal citation on this page is an ECF No. and can be pulled from that docket. The two January opinions are quoted from the filed text.
The state indictment is quoted from the signed copy published by the District Attorney’s office, and the August 17 scheduling order from the copy filed in Part 32 — both in full, both short. The People’s October 9 response is quoted from the copy Courthouse News published.
The two state decisions that matter most — the September 2025 omnibus decision and the May 2026 suppression decision — are summarized here from contemporaneous reporting of them, with one quoted passage from the first. That is a weaker chain than the rest of the page and is marked as such below.
What is not here yet
The People answered the double jeopardy motion on October 9, 2026, and the defense replied at the end of the month. The Side by Side View sets the two side by side, each quoted from its own papers. The defense reply is quoted from the court-stamped copy LA Magazine published.
New York County Supreme Court has no public docket of the kind PACER provides, so the state record here is not a complete list of filings in the way the federal one is. Where a state filing is described, it is because a copy or a reliable account of it is public — not because the docket was read end to end. Assume the state side is less complete than the federal side, because it is.
The Pennsylvania case is noted once and then dropped. It has never been tried and nothing in it bears on the question this page is about.
The victim, and the inference
Brian Thompson was fifty, and had a wife and two sons. The case is interesting for reasons of statutory construction, and a page organized around statutory construction can quietly turn a killing into a puzzle. He is named here every time the record names him, and the one thing nobody in any of these courtrooms has disputed since August 14, 2026, is how he died.
One reading on this page is an inference rather than a fact: that the open plea was entered to trigger the state double jeopardy bar. Neither side has said so on the record. It is marked as an inference where it appears, and it is the only place this page reasons about motive.
What this is not
Not legal advice, not a finding, and not a verdict. He has been convicted of two federal stalking offenses by his own plea and has not been tried for murder by anybody. The state counts are allegations and remain allegations, and the question of whether they can be tried at all is undecided by the only person who gets to decide it. Where the record does not reach, this page says so and stops.
Tell me what I got wrong
If something here is missed, misrepresented or unfairly portrayed, let me know. Point me at a filing or record and I will verify it on my end. I actively look to correct, improve and remain unbiased.

Record reviewed through November 8, 2026. Both cases are live: the federal one awaits sentence on December 18, and the state one awaits a decision on a motion both sides have now briefed. This page will be wrong in some particular within weeks, which is the condition of writing about a case while it is still happening.
Terms
Plain English
Words this page uses because the courts use them. Nothing here is special to this case.
The paperwork
- Docket
- The court’s numbered list of everything filed in a case. Entry 42 is the forty-second thing filed.
- ECF No.
- How a federal filing is cited: its docket number. A number after a dash, like 59-2, is an attachment to it — usually an exhibit.
- Indictment
- The document a grand jury returns to start a felony prosecution. It lists the charges and nothing else; it is not evidence of anything.
- Count
- One charged offense. An indictment with eleven counts charges eleven separate offenses, and a jury answers for each one separately.
- Grand jury
- A panel that hears the prosecution’s evidence in secret and decides whether there is enough to charge. It does not decide guilt.
- Transcript
- The word-for-word record of a hearing. Cited by page and line, so 12:7 means page 12, line 7.
- Under seal
- Filed with the court but kept off the public record. Both sides and the judge can read it; nobody else can.
How a case moves
- Arraignment
- The hearing where a defendant is formally told the charges and enters a plea to them.
- Motion
- A formal request that the court do something. The other side files an opposition or response; the moving side may then reply.
- Suppression
- Keeping evidence out of a trial because of how it was obtained. The evidence may be entirely genuine; the question is only whether the police were entitled to get it that way.
- Inventory search
- A search of a detained person’s property to log what is in it, done to a standard procedure rather than to look for evidence. Lawful without a warrant, which is why the procedure itself gets litigated.
- Miranda warnings
- The caution police must give before questioning someone in custody. Answers given before it are generally inadmissible; answers to routine booking or safety questions generally are not affected.
- Voir dire
- The questioning of prospective jurors before a trial, to decide who sits on it.
- Interlocutory appeal
- An appeal taken in the middle of a case, before final judgment, usually only where a statute allows it.
- Presentence report
- An investigation by the probation office, ordered after conviction, that the judge reads before sentencing.
- Learned counsel
- A lawyer experienced in death penalty cases, appointed at public expense whenever a federal case is capital. Required by statute, not discretionary — so the appointment arriving and being withdrawn marks when a case was and was not capital.
- Primary jurisdiction
- Which of two governments holding claims on the same defendant gets to deal with him first. It usually follows who arrested him.
- Rule 600
- Pennsylvania’s speedy-trial rule. It normally requires trial within a year of the complaint, but time a defendant is unavailable does not count against it.
Pleas
- Open plea
- A guilty plea entered with no agreement from the prosecution — no charge concessions, no sentencing recommendation. The defendant gives up the trial and keeps none of the usual consideration for it.
- Plea agreement
- The usual arrangement: a plea in exchange for something, normally dropped charges or a position on sentence. There was none here.
The tests in this case
- Double jeopardy
- The bar on being prosecuted twice for the same offense. New York’s statutory version is broader than the Fifth Amendment’s and reaches across sovereigns.
- Dual sovereignty
- The doctrine that a state and the federal government are separate sovereigns, so a prosecution by each for the same conduct is not the same offense under the Fifth Amendment.
- Criminal transaction
- Conduct closely connected enough in time and purpose to count as one episode. New York’s double jeopardy statute works on transactions, not just on single acts — which is why the date on a count matters.
- Crime of violence
- For these statutes, a felony that has as an element the use, attempted use, or threatened use of physical force against the person or property of another.
- Predicate offense
- An offense that another, more serious charge is built on top of. If the predicate fails as a matter of law, the charge built on it fails with it.
- Categorical approach
- A method that ignores what the defendant actually did and asks only whether the offense, as written, always requires force — judged by the least serious conduct the statute could cover.
- Legally insufficient
- The evidence put before the grand jury, taken at its best, could not establish an element of the charge. The count goes without any finding about whether the defendant did it.
- Armed felony
- A New York classification attaching to certain offenses committed with a loaded weapon. It restricts what sentence and what plea are available.
