On March 1, 2026, Monique Delacroix contacted PGPD after her son Antoine failed to respond to calls or texts for 36 hours — unusual behavior she described as unlike him. A welfare check found the apartment unlocked, a meal partially prepared in the kitchen, and Antoine nowhere on the premises.

A plain brown box — sealed with brown packing tape, no label, no postage — was found on the kitchen table, open and apparently inspected by the subject. A small amount of dark granular material was found inside the box lining. Submitted to FBI lab for analysis. Results pending.

Neighbors on Hampton Park Blvd described seeing a gray cargo van parked across the street on February 28th for approximately 25 minutes. No delivery was observed — van departed without anyone exiting. Antoine was observed retrieving a package from his porch earlier that same afternoon.

Antoine had no criminal history, no known enemies, and no financial distress. His freelance IT work was entirely remote. His primary laptop and phone were not found at the scene — the only instance in the case cluster where devices were not left behind.

Sandra Kim was reported missing on March 18, 2026 after failing to appear for her morning homeroom class at Bladensburg High School without notice. Administration contacted family; her mother in Greenbelt confirmed she had not heard from Sandra since the evening of March 16th.

A welfare check at her Annapolis Road apartment found the door locked but unlocked via spare key held by property management. Sandra's car, coat, and personal items were inside. The apartment was neat and undisturbed.

Sandra had recently separated from her husband, David Kim, who was interviewed and cleared via alibi. There were no indications of financial trouble, mental health crisis, or domestic threat. Students described her as upbeat and engaged the week prior to her disappearance.

This is the only case in the cluster where the package itself was not recovered — believed to have been taken from the scene or destroyed. The absence of the package is a notable deviation from the cluster pattern.

Darius Pemberton was reported missing by his wife, Roxanne, on April 9, 2026 after he did not return from a walk he described taking the previous evening around 8:00 PM. Roxanne stated he had been acting unusually for two days, describing him as distracted and "not himself" since receiving a package on April 7th.

The package — a plain brown box — was found on the kitchen table, sealed and unopened. This is the only package in the cluster recovered in an unopened state. It was submitted to FBI Evidence Lab in Quantico. Preliminary findings noted: no fingerprints on exterior, no identifiable shipping material, and a notable electromagnetic signature on the outer surface that investigators have not yet explained. Full analysis pending.

Roxanne confirmed Darius received the package on the afternoon of April 7th, carried it inside, and told her "it must be a mistake — I didn't order anything." She noticed him checking the front window several times that evening. On April 8th, he was quiet throughout the day. At approximately 8:00 PM, he said he was going for a walk and never returned.

Darius is a retired USPS carrier of 28 years with no criminal history, no known health issues beyond managed hypertension, and strong community ties in Oxon Hill. His retirement card, medication, and reading glasses were left on the nightstand.

Marcus Webb was reported missing by his sister Tamara Webb on May 2, 2026 after she was unable to reach him following a text exchange in which he mentioned receiving an unexpected package. Tamara drove to his Forestville home and found the door unlocked, his truck in the driveway, and Marcus nowhere inside.

A plain brown box was found on the living room coffee table, open. Interior examination found fragments of a dark wax-like material consistent with the material found in Case 2 (Delacroix). Both samples submitted to FBI lab for comparative analysis.

A neighbor across the street, who asked not to be identified, confirmed observing a gray cargo van briefly stopped in front of the residence at approximately 3:00 PM on May 1st. A courier in dark clothing delivered the box and departed without interacting with the subject. The van bore no visible markings.

The geographic proximity to Case 1 (Hargrove, Seat Pleasant — 3.4 miles) and the similar wax residue found in both Cases 2 and 5 represent the most significant cross-case forensic link to date. FBI is treating this as a priority lead.
