Chalice attended a birthday party at the Embassy Suites. Multiple eyewitnesses reported that Chalice appeared heavily intoxicated and was physically assisted into a vehicle when departing the gathering.
February 3, 2024 · 3:58 AM
Last Confirmed Sighting — Dallas, TX
On-site Airbnb surveillance footage confirms Chalice was inside the Luxia Midtown Park complex at 8107 Manderville Lane, Apt. 1519, Dallas, Texas. This footage directly contradicts the initial account given by Salahssie Donatto ("Big S"), the last known person reported to be with Chalice prior to her disappearance.

Final Phone Ping & Deliberate Device Destruction — Dallas, TX
Chalice's mobile device last pinged at Walnut Hill Lane & North Central Expressway, Dallas, Texas — approximately one mile from the Airbnb location. The device was moved in the 38-minute interval following the 3:58 AM surveillance footage, after which it was deliberately rendered inoperable. Carrier records confirm intentional tampering.
February 5, 2024 — Monday Morning
Deyon Mason Williams Appears at Chalice's Workplace
Deyon Mason Williams, father of Chalice's four children, appeared at her workplace on the Monday morning following her disappearance, seeking her tax information. Per the record available to AIDBIPOC, he has never publicly assisted in searching for her.

Trafficking-Platform Advertisements Bearing Chalice's Likeness
Escort advertisements bearing Chalice's likeness appeared on known trafficking-associated platforms both before and after her disappearance. Phone numbers linked to these postings have been traced to an individual in Roswell, Georgia. This information has been provided to investigators.
Pre-2024 — Approximately Twelve-Month Period
Coordinated Relocation Pressure
A coordinated, year-long effort to pressure Chalice to relocate to Dallas preceded her disappearance. The onset of this pressure coincided with the first appearance of trafficking-platform advertisements using her likeness.

III. Evidence Categories Referenced in the Demand Letters

A. Surveillance Evidence

Airbnb hallway surveillance footage from the Luxia Midtown Park Airbnb complex at 8107 Manderville Lane, Apt. 1519, Dallas, Texas, for the night of February 2–3, 2024. Footage at 3:58 AM on February 3, 2024 confirms Chalice was inside the complex and directly contradicts the initial account of Salahssie Donatto.

B. Telecommunications Carrier Records

Mobile carrier records for Chalice's phone reflecting: (i) final GPS ping at 4:36 AM on February 3, 2024 at Walnut Hill Lane & N. Central Expressway, Dallas, TX; (ii) intentional tampering inconsistent with battery drain, user disablement, or routine device failure.

C. Eyewitness Accounts

Statements from multiple eyewitnesses present at the Embassy Suites gathering of February 2, 2024 reporting that Chalice appeared heavily intoxicated and was physically assisted into a vehicle when departing.

D. Digital Evidence of Trafficking-Platform Activity

Standing & Good Faith

AIDBIPOC submits this Case Documentation Package in good faith, in its organizational capacity as a public-interest 501(c)(3) advocating for accountability in the investigation of missing persons whose circumstances reflect trafficking indicators. All factual claims in this package are drawn from the documented record available to AIDBIPOC and from sources represented to AIDBIPOC by Chalice's family, advocacy contacts, and ongoing public coverage of the case. AIDBIPOC welcomes independent verification of each element by the reviewing agency.

Note on Evidentiary Standards: This package is prepared by a public-interest nonprofit organization in an advocacy capacity, not by a licensed law enforcement investigator or a forensic evidentiary custodian.
