Alexander Silva III: The Houston Timeline and the Monitor Record
Four dated reports distinguish personal contact, device activity, and later family accounts.
Abstract
Alexander Silva III, known as A.J., was 19 when he disappeared from Houston in 2021. Gabby Hart’s August 1, 2022 FOX 26 report dates his mother Conception Moreno’s last sighting to April 5, 2021 and her missing-person report to May 6.2
A Reported Sighting
Randy Wallace’s September 27, 2021 report also gives April 5 for the family’s last sighting.1 The underlying dated statement was not independently reviewed.
Holly Galvan Posey’s December 2024 family profile quotes Moreno describing her son as outgoing and fond of dancing.4 This personal context does not establish the timing or cause of his disappearance.
The Reported Device Activity
Wallace described April 11–14 monitor events and an April 16 tampering entry in court records. He also reported April 17 pings in the Dacoma and West T.C. Jester areas.1 The court file and full log were not independently reviewed.
Hart relayed Moreno’s interpretation of records: an April 14 tampering indication, an outage on April 15, renewed activity on April 16, and about 41 hours at a Lumberdale warehouse. The report dates the final shutdown to April 17 at 11:49 p.m.2
A device trace requires its own timeline label. It does not establish who was wearing the device at every moment. The published summaries do not reproduce the complete trace or define every event; differences in those summaries do not establish competing witness accounts.
What the Later Date Describes
Posey’s December 16, 2024 KPRC report uses April 16, 2021 for the warehouse account.4 It does not reproduce a separately dated witness statement. That published date should retain its source and context.
Sourced Accounts and Questions
Here’s where you come in. Can you compare the mother’s dated account with the May 6 report, separating the observation from the reporting date?2 Those documents could clarify what each date records.
Can you align each monitor entry’s timestamp and event type with a separately documented sighting?1 A complete log could clarify whether published descriptions concern the same system event.
Can you locate the document supporting the April 16 warehouse date and determine whether it records a person’s observation or a device event?4 That distinction could clarify the timeline.
As you examine later family accounts, can you identify what is attributed to relatives and what has independent documentary support?3 Keep the source, date, and question in a Research File in Almost Solved.

Later Reporting and Its Limits
Hart reported that Houston police considered a reported witness unreliable and continued a missing-person investigation.2 That dated assessment does not establish the present case status or an outcome.
Damali Keith’s March 4, 2024 report interviewed Moreno and uncle Paul Vasquez. Vasquez described a private investigator, a dog alert, and messages the family interpreted as ransom demands.3
Those are attributed family accounts. The reviewed report does not reproduce a forensic analysis or authenticated messages.3 They do not confirm an identification, abduction, death, or any person’s responsibility.
Posey’s December report describes Vasquez’s leafleting and advocacy, and reports his death in November 2024.4 It is a family account, not an identification of Alexander or a forensic resolution.
Scope and Method
This study compares dated original reporting. The underlying police, court, monitor, private-investigator, and forensic records were not independently examined. Current NamUs fields were unreadable. Published device descriptions do not prove the wearer’s location; later family accounts are not official identifications or findings. No present case status, responsibility, or outcome is inferred. Unmatched results are excluded.
