Cristina Tomas Martin -- ATTEMPT TO MATCH to JANE DOE

Resumen: Este artículo examina la posible coincidencia entre Cristina Tomas Martin (NamUs #MP15992), desaparecida el 25 de junio de 2007 cerca de Altar, Arizona, y una Jane Doe (NamUs #UP6413) encontrada en 2009 en Arizona, con muerte estimada entre 2004-2007. Shane Lambert sugiere un 50-70% de probabilidad de que sean la misma persona, basándose en similitudes visuales, etnia, edad y ubicación, aunque hay discrepancias en altura. Se necesita ADN para confirmarlo. Lambert, involucrado desde 2016, pide compartir el caso en Guatemala para encontrar familiares.

Cristina Tomaz Martin

VITAL DETAILS

Ethnicity: Hispanic/Latino
Sex: Female
Age at time of disappearance: 19 years old
Birthdate: June 26th, 1987 to June 25th, 1988
Hair details: Black
Eye details: Black or dark brown
Scars: None known
Height/weight: 4-foot-10 to 5-foot and 100 to 130 pounds
BMI*: The missing person was overweight by BMI at the time of the last contact.
  • Please, Google BMI if you aren't familiar with the phrase.
  • BMI can be important even when there are photographs to look at. It is an indicator that helps get an idea of what a person's body might have looked like.
Attempt to Match to Jane Doe: In my opinion, Cristina Tomas Martin might be Jane Doe #UP6413 at NamUs. This is worth attempting to rule out.

AI's Take on the Chances of This Being a Match: Reasonably High


The likelihood that Cristina Tomas Martin (NamUs #MP15992) and Jane Doe #UP6413 are the same person is estimated at 50–70%, factoring in a strong visual similarity noted between Cristina’s photo and the Jane Doe’s compositesketch (Grok, 2025). This probability also considers overlapping timelines (last seen 2007 vs. estimated death 2004–2007), matching Hispanic/Latino ethnicity, female sex, close ages (19 vs. 16–21), and nearby locations (Altar, AZ, vs. San Miguel Village, AZ).

However, a height discrepancy (4'10"–5'0" vs. 5'5") and lack of matching identifiers lower certainty. Forensic evidence like DNA is needed for confirmation (Grok, 2025).

Cristina Martin, a missing person, was last heard from on June 25th, 2007 when she was 19 years old. This is a case that I have some familiarity with, as I submitted an ATTEMPT TO MATCH in July of 2016. I thought then, and I think now that Cristina Martin is the Jane Doe at NamUs #UP6413.

What stands out with this attempt to match is the composite sketch of the Jane Doe and Cristina's known likeness as per the photographs of her. They really do look like one and the same person in a lot of ways.
Also, at the time of her disappearance, Cristina was 19 years old.

Furthermore, the timeline makes some sense. The Jane Doe was found in 2009, but she was thought to have died in the range of 2004 to 2007. The higher end of that range is close to matching up with when Cristina was last seen.

I had some email exchanges with the authorities on these two cases back in 2016. I think I had published something somewhere or other but I can't find it now, so perhaps I deleted it. I still have the emails I sent, however.

Writing in 2021, I'm actually a little surprised that the cases are still active. As per the email exchanges I had, they were looking for a next of kin for Cristina. The lead seemed to be in Guatemala, however, I got the impression that finding the NOK was difficult. My advice to people who are interested in this case is to share this link with hashtags that target Guatemala or major cities in that country.

If these kinds of mysteries intrigue you, then you can find more like them at Websleuths.com or by clicking around this site. The hashtag I use when I try to match up a Jane Doe or a John Doe to a missing person is called "Attempt to Match." You can find it in the hashtags below.

I have reason to believe that the missing person may have been from Guatemala. Accordingly, I have included translations in the main languages for that country in hopes the SEO improves that country and helps her family find this webpage. - Shane Lambert

Jerry Strickland, Melissa (Missy) Munday -- What Happened After the "Unsolved Mysteries" Episode 2

Image
By: Shane Lambert Time of writing : December 5th, 2020 If you are a fan of the old "Unsolved Mysteries" episodes that Robert Stack hosted in the 1980s and 1990s, then you might remember Episode 2 of Season 1. That program opened with a murder case, one that saw Elmer DeBoer brutally killed, allegedly at the hands of one Jerry Strickland. Wed, Feb 19, 1992 – Page 22 · Detroit Free Press (Detroit, Michigan) · Newspapers.com The story of Strickland, his girlfriend Missy Munday, and the murdered DeBoer ended with viewers learning about the arrest of Strickland after the episode aired. For those wondering what happened next, here's a rundown. According to an article in the Detroit Free Press from August 17th, 1988, Munday testified against Strickland and named him as the murderer of DeBoer. She claimed that Strickland confessed to the murder. Charges against her were dropped because of this. Wed, Aug 17, 1988 – Page 4 · Detroit Free Press (Detroit, Michigan)...

Missing Kids and Their Bicycles - Cases of Dario Cicolecchia, Janice Pockett, and Others

Image
By: Shane Lambert Season 2 of the hit TV show Forensic Files included an episode (Episode 12) that contained information that those who work on missing person cases should note. The episode tells of the missing person's case of Dario Cicolecchia, a boy in Switzerland who went missing in 1993. Importantly, this boy was found, his murderer was apprehended, and this murderer also made statements to the police about how he operated. I think there's a nugget of information that's worth extracting from this case and using it as food for thought in similar cases. Dario Goes Missing: Secluded Area, Unwittingly Leaves Trail for Pedophile to Follow Dario went missing after departing his home on a bicycle to go fishing. He was later found dead and mutilated in a Swiss cornfield. As described in the episode, forensic Medicine, the branch of forensics that deals with the body, was used in this case and it was discovered that the boy had been drowned. Investigators found diato...

The Mystery of Beverly Sharpman's Disappearance: The 1947 Philadelphia Missing Person Case

Image
By: Shane Lambert Original time of writing: February 18th, 2018 Tonight I looked at the mysterious case of Beverly Sharpman, an individual who was last seen on September 11th, 1947 in Philadelphia. NamUs has her listed as 16 years old at the time of her disappearance. However, all the newspaper articles I looked at indicated that she was 17 years old at the time. Generally, she is reported as 17 years old, which has always meant that she is a missing child. Exploring the Enigma of Beverly Sharpman’s Disappearance The case stands out to me because of the huge effort that individuals in Beverly's family made, especially her mother Nettie, in attempting to find her. Furthermore, I'm not convinced that Beverly Sharpman died at a time close to her disappearance. Lastly, I'm not convinced that the love that Beverly's family felt for her was entirely reciprocal. My opinion in this cloudy case is that Beverly disappeared voluntarily. Have a look at t...

James Hugh Wilson -- Missing Since Plane Crash in 1970

Image
Missing Person : James Hugh Wilson Last-contact date : January 28th, 1970 Area MP was last seen : Cleveland, Ohio Link to government source : NamUs #MP62284 Ethnicity : White Sex : Male Age at time of disappearance : 48 years old Hair details : gray or graying Eye details : blue Height/weight : 6-foot to 6-foot-1 and 180 to 220 pounds Details from NamUs : this individual was on a plane that crashed into Lake Erie on the day of his disappearance. Note: this article is not about the musician, James Hugh Wilson, who plays the cello. James Hugh Wilson, a missing person, was last heard from on January 28th, 1970 when he was 48 years old. When James disappeared, he was of the Cleveland, Ohio area. What stands out in this case, is the elephant in the room: James was on a plane that crashed. They recovered most of the bodies, however, James was not among those recovered. Someone lost in a plane crash might be lost for all time. However, his remains might turn up someday. From what I read, the ...

The Rahway Jane Doe from March 25, 1887 (New Jersey)

Image
By: Shane Lambert Updated: February 16th, 2021 The Rahway Jane Doe is an individual who was murdered in the town of Rahway, New Jersey on March 25th, 1887. The mystery of the murder victim's identity stands out, because it is the oldest unsolved mystery listed at DoeNetwork.org.  I researched this mystery using online newspaper databases for a good two hours on February 5th, 2017. In my opinion, there is very little chance of conclusively solving this mystery for websleuths even with modern technology, like searchable newspaper databases, that wasn't available in 1887. The "clews" in this case (that's the 1887 spelling of "clues") are 99% red herrings if you ask me. Perhaps the best chance in identifying her is through DNA and the family-tree method.  Why bother with this case? If you are interested in this case then it's not so much about justice or helping surviving relatives learn where a loved one went, is it? After all, the perpetrator ...

Dottie Caylor's Disappearance - What Happened After the "Unsolved Mysteries" Episode

Image
By: Shane Lambert 03 Apr 1998, Fri The News Journal (Wilmington, Delaware) Newspapers.com Dottie Caylor's disappearance was featured in one of the opening episodes of the "Unsolved Mysteries" television program. According to a Youtube video I watched , it was in the pilot episode. From Wikipedia, it was a special program that was aired before the series became the series that fans grew to love. According to a newspaper article I consulted (The Leaf-Chronicle out of Clarksville, Tennessee), the show aired on November 29th, 1987. If you watched the "Unsolved Mysteries" program and wondered what happened with this case, then this article is for you. 29 Nov 1987, Sun The Leaf-Chronicle (Clarksville, Tennessee) Newspapers.com Firstly, this individual, as of the time of writing (December 17th, 2021), still has an active missing person's profile with NamUs, America's national database of missing people.

NamUs #MP8602 - Notes on Ashley Fuller Reed

Image
By: Shane Lambert The Original Time of Writing : October 1st, 2018 Updates : February 25th, 2025 On October 1st, 2018 I took a look at the missing person's case of Ashley Fuller Reed ( NamUs #MP8602 ). I read over her case at NamUs and then used an online-newspaper database to look at the reporting from 1990 that covered her case. I feel that anyone websleuthing this case should know about details that I came across during this research. It's my opinion that NamUs doesn't provide enough information. Furthermore, I took a look at the greater region and the large time frame associated with this case. I've noted numerous cases of white females going missing from Texas after experiencing car troubles between 1988 and 1994. These cases may or may not be related. NamUs says that Reed was last heard from on January 15th, 1990, a Monday holiday (Martin Luther King Jr. Day). One newspaper article (El Paso Times/March 24th, 1990/page 13) contradicted that and said that she ...
