My search for Juan Corona began with the statement that he was a 'primo' or cousin to the Medina family, which became the ultimate research question: is this man truly related to my husband? Or was this simply an erroneous assumption, based on family lore?
Let's get to the answer.
Follow the brother (and the father and the mother and aunt...)
An important technique in genealogical research is to expand the scope to multiple family members - beyond those of interest. Records of brothers, sisters, aunts, and uncles can reveal critical insights into the lives of direct ancestors. Indeed, a full picture of each family member enriches the stories of all. This proved to be the case in my search for Juan Corona.
The Corona family entry in the 1930 Mexico National Census suggests that Natividad and Juan were half-brothers. With confirmation that Cándida Uribe was the mother of Juan, and the implausibility that she was the mother of Natividad (due to their proximity in age), the next step was to identify Natividad's mother and perhaps find a clue to the relationship to the Medina family.
For Mexican research, I rely heavily on the FamilySearch database, filled with hundreds of millions of records from the Catholic Church and the Regístro Civil - some indexed and others not. Using the search tools available for the indexed records, I looked for more information about Sebastian Corona and his first marriage (children, marriage record, etc.). No luck. There simply were no indexed records in FamilySearch matching this family. I then began the old-fashioned (and incredibly time-consuming) process of searching the unindexed Civil Registration records page-by-page.
The problem with this approach was that I was using erroneous information discovered in books written about Juan Corona. Nearly all references I consulted (which largely included research conducted by lawyers, and not genealogists) suggested that the family was from Autlán. Incorrect. It appeared I had hit a brick wall.
And then, using the Ancestry.com database of Mexico to U.S. Border Crossings, I located a record for Natividad. It proved to be the wrecking ball that busted through my brick wall.
Within this one document is Natividad's date and place of birth, the name of his wife, a photo, and...the name of his mother! This piece of information was the key to unlocking the connection to the Medina family.
Using this new information (and, in October, the release of Ancestry.com's collection of indexed Mexican Civil Registration records), I quickly discovered the rest of the story.
Natividad Corona was born on December 30th, 1922, as indicated on the border crossing document. This was supported by the civil registration of his birth. Interestingly, he is listed as 'hijo ilegítimo' which would explain the reason for no marriage records for Sebastian and Gerónima.
He died in Guadalajara in 1973 (following the storyline of most investigators in the U.S. that he fled to Mexico during his brother's trial).
The next and final step to answering the research question was to build the family tree of Gerónima Sanchez.
It didn't take long to tie into a tree I had long researched. My husband's great grandmother was Francisca Sanchez Ramos. The first record I discovered, though tragic, connected Gerónima to Sebastian Corona and to Francisca Sanchez. It was a 1927 death record for Señora Gerónima Sanchez, in which the informant was Sebastian Corona, and the parents were listed as Pascual y Basilia Ramos. Pascual and Basilia were Francisca's parents, as well.
Natividad Corona's mother, Gerónima, was my husband's great grandmother's sister. Put another way, Natividad (Juan's half-brother) was my husband's grandfather's cousin.
Ultimately, this confirmed that Juan Corona and my husband are not related. Unfortunately, it never quite resolved the question as to whether or not I married an axe murderer: Natividad was also suspected of committing the crimes.
Eh. I'll take my chances. ;)

I am related to Juan Corona through the Michel last name. I have been researching my family for 32 years and have been doing it professionally for a little more than 10 years. I was looking for my connection to him through the Corona last name but I found it through the Michel line.
Hi Lisa, I am a Corona researcher myself. I have been working tirelessly trying to identify each of the victims, which has been a painstaking task. I have been looking for any info about Natividad and it has eluded me for years. You cannot imagine how exciting it is for me to see his face and a certificate of death. This is a huge piece of the puzzle, trying to separate misinformation and lore from the truth. I am currently writing an entry about Natividad and decided to put his name in Google for about the 1,000th time and this was the first thing to pop up.I don't know why facts about him have been elusive to me for so long. I nearly cried. Thank you for sharing this info. You may (or may not) know, that officials never could substantiate Natividad's death. So this is really a huge deal.

Anna - I am so glad to hear that this research was useful. While the initial motivation for my investigation was personal, I learned much more than I had anticipated about the case. It is quite satisfying to hear that this post may have advanced (in some small way) your work. Best of luck to you!

It's my understanding that officials obtained the death certificate however they were never certain it was genuine.

Oh, how interesting. I have not heard that. As far as my husband's family is aware, he died in 1973 as indicated in the death record.

It is something that is mentioned in at least one documentary.
