On the morning of October 14, 2024, the body of ELIAS HARGROVE, 61, senior partner at Hargrove & Voss Capital Management LLC, was discovered in his private office on the 19th floor of the Alderton Building, downtown Carver City. The initial ruling by the responding unit was acute cardiac arrest, natural causes. The case was closed within 72 hours.

Three weeks later, an anonymous package arrived at MHD containing a partial router traffic log and a single handwritten note reading: "He didn't die. He was erased. Check the time of the last keystroke."

You are the re-examining investigator. All documentation recovered from the original scene, digital systems, and subsequent warrants has been compiled in this interface. No lead has been pre-filtered. No clue has been highlighted. You must read everything.


The case has three structural locks. Each lock requires you to identify a specific contradiction in the raw data and input the precise answer in the control panel below. Answers are case-insensitive but must be exact values from the documents — a name, a time, a substance, or a number.

Begin with Category A. Take notes. Cross-reference everything.

⚠ This file contains real-seeming forensic, medical, and financial data. All persons, entities, and events are entirely fictional. No hints will be provided by the interface. Estimated investigation time: 90–180 minutes.

◈ THREE-STAGE VERIFICATION LOCK — INVESTIGATOR INPUT REQUIRED
Stage 1 — The Core Anomaly
The official cause of death is cardiac arrest. Cross-reference the autopsy body temperature reading at time of discovery against the 911 dispatch log arrival time and the pathologist's cooling rate formula. What is the latest possible time of death the pathology data permits? (Format: HH:MM, 24-hr)
Stage 2 — The Technical Discrepancy
One suspect provided a verbal alibi placing them outside the building during the calculated death window. Cross-reference security badge swipe records, router device logs, and toll transponder data. Which suspect's digital footprint directly contradicts their stated alibi? (Full name)
Stage 3 — The Fatal Material Link
The prime suspect claims they never touched Elias Hargrove or his personal effects. The full toxicology report and the crime scene physical catalog together contain one item that places this person at the exact micro-window. What is the specific substance found in the victim's bloodstream that is only consistent with the compound stored in the suspect's private office supply cabinet? (One word, substance name)

⊕ CASE CLOSED — CONVICTION VIABLE

SUSPECT IDENTIFIED: DIANA VOSS

You have successfully reconstructed all three tiers of the evidentiary chain.

Stage 1: The body temperature of 31.1°C recorded at 07:44 AM is physiologically inconsistent with the official cardiac arrest ruling at 06:00 AM. Algor mortis cooling data places the latest possible time of death at no earlier than 02:20 AM — over three hours before the building's cleaning staff allegedly discovered him. The 911 call was placed at 07:31 AM, meaning the body cooled for approximately 5 hours, not the stated 1.5. The scene was staged.

Stage 2: Diana Voss claimed she left the Alderton Building at 22:45 on October 13th and drove directly to her home in Westfield, spending the night there. However, her proximity card shows a badge swipe at the 19th floor service entrance at 01:54 AM on October 14th. Her home router shows her laptop disconnecting from the home Wi-Fi at 00:47 AM — she was never home.

Stage 3: The toxicology panel identifies digoxin at 4.8 ng/mL — a dose range lethal in patients with a pre-existing arrhythmia (consistent with Elias Hargrove's documented condition). The crime scene catalog notes a crushed tablet residue on the inner rim of the victim's whiskey glass. Diana Voss's office supply cabinet (Vault Access Manifest, item V-09) contains an unopened foil strip of Lanoxin 0.25mg tablets — brand-name digoxin, prescribed to her deceased mother and never returned to pharmacy. The fingerprint on the glass base matches Voss's right thumb (Latent Prints Ledger, Print ID: LP-004).
