Missing Persons: What the Term Means

A missing person is someone whose whereabouts are unknown after being reported missing to law enforcement. A missing-person case may involve a child, teen, adult, elderly person, vulnerable person, runaway, possible abduction, or suspicious disappearance.

A case is often treated as urgent when the disappearance is out of character, the person may be in danger, the person is young or vulnerable, or there are signs of possible criminal involvement. Law enforcement commonly relies on details such as the person’s name, age, physical description, last known location, clothing, travel plans, vehicle information, medical needs, and who last saw them.

Missing-person cases may be grouped by circumstance, including endangered, involuntary, juvenile, catastrophe victim, runaway, unknown, or suspicious circumstances. The FBI’s NCIC Missing Person File uses categories such "disability," "endangered," "involuntary," "juvenile," "catastrophephe victim, and other. NamUs also serves as a national resource center for missing, unidentified, and unclaimed person cases.

If someone goes missing, act quickly. Try calling and texting, check places they normally go, contact family and friends, gather recent photos and identifying details, and file a report with local law enforcement. Sharing accurate public information can help, but rumors, assumptions, and unverified accusations can harm an investigation.

The more specific the details are, the easier it is for police, media, advocates, and the public to assist. Early reporting creates a record and gives investigators a starting point. In serious cases, those first details can make the difference between a safe recovery and a long-term cold case.

Charlotte Denese Doles, I did not find a reliable case photo in the image results returned here.For Donna Kay Saunders Basden, the image results I found do not appear to match the missing-person case reliably, so I’m not using them as case photos.Chriscinda Joy Stephens, I found a collage-style photo set from a missing-person sourceYes, but not because of the polygraph alone. A failed polygraph is an investigatory lead, not evidence by itself; the strongest reason to pursue DNA testing in the Doles case would be that the disappearance is long unsolved, suspicious, and involves a documented last-known companion, which makes biological reference samples worth comparing if they exist. Best-practice guidance on missing-person identification emphasizes DNA when a case is old, unresolved, and there are possible family-reference or direct-reference samples available. Those recommendations specifically note that DNA can be used with relatives or direct items such as medical specimens or personal effects, and that older cases may benefit from mtDNA or kinship testing when direct samples are limited. �In Doles’s case, the public record says her boyfriend failed a polygraph and the case remains unsolved, but no public source here shows a completed modern DNA comparison. That means DNA testing could still add value if investigators can collect family reference samples or locate preserved evidence from the original file. �Here’s a one-paragraph investigative memo version: Charlotte Denese Doles, Mylette Josephine Anderson, Donna Kay Saunders Basden, and Chriscinda Joy Stephens each present a different suspect-profile pattern in Jacksonville missing-person work: Doles is the clearest boyfriend-linked case, with Henry Mann identified as the last known companion and public reporting noting a failed polygraph but no charge; Anderson is a **strangera side-by-side suspect-profile comparison of Doles, Mylette Anderson, Donna Basden, and Chriscinda Stephenson.Here is a side-by-side suspect-profile comparison for the four Jacksonville cases. The key difference is whether the public record points to a boyfriend, a stranger, an unidentified male, or a named external contact. [1][2][3][4]## Suspect profile table| Case | Last-known contact | Suspect profile | Public confidence | Notes ||---|---|---|---|---|| Charlotte Denese Doles | Boyfriend, Henry Mann | **Boyfriend-linked POI** | Medium | Public reporting says she went to the movies with Henry Mann and he reportedly failed a polygraph, but no charges were filed in the disappearance. [1][5][6] || Mylette Josephine Anderson | Unknown / alleged stranger suspect | **Stranger-suspect theory** | Low–medium | One suspect cited was Paul John Knowles, but the public summary says police later believed his confession was probably false. [2] || Donna Kay Saunders Basden | Unidentified man | **Unidentified male companion** | Medium | She reportedly left work with an unidentified man, which makes the case suspicious without naming a confirmed suspect. [3][7] || Chriscinda Joy Stephens | Danny Vidal | **Named stranger / outside associate** | Medium | The public summary says the last person known to have seen her was Danny Vidal, described as armed and dangerous. [4][8] |## What separates themDoles is the clearest **boyfriend-linked** case because the named male is her intimate partner and the public reporting includes a polygraph reference. [1][5][6]Mylette Anderson is a **stranger-suspect** case because the suspect theory centers on Paul John Knowles, an outside offender figure, but the confession is considered unreliable. [2]Donna Basden sits in the middle: the public record names no one, only an **unidentified man**, so it is suspicious but not fully person-linked. [3][7]Chriscinda Stephens is the cleanest **named stranger / outside associate** profile because the last known contact is specifically identified as Danny Vidal. [4][8]## Investigative useIf you are coding these for analysis, use these labels:- Doles: `boyfriend-linked`.- Mylette Anderson: `stranger-suspect theory`.- Basden: `unidentified male companion`.- Stephens: `named outside contact`. [1][2][3][4]That gives you a clean framework for comparing relational proximity, evidentiary strength, and whether the public source names a person, a role, or only an unidentified male. [1][2][3][4]If you want, I can turn this into a **one-paragraph investigative memo** or keep building a larger suspect-profile matrix.Charlotte Denese Doles
