How a Cook County sheriff’s detective may have solved a 93-year-old mystery
The disappearance of Mary Agnes Moroney has gone unsolved for nearly 100 years.
But answers to this Chicago mystery seemed to reveal themselves only months after a Cook County detective began looking into her case last year, this time with the help of commercial DNA tests.
Now, members of two families are convinced she is the woman who died 20 years ago as Jeanette Burchard of Florida.
Mary Agnes’ nephew, Don Moroney, and Burchard’s daughter, Terri Arnold, reached that conclusion based on the work of Jose Rodriguez, a detective with the Cook County sheriff’s office. Rodriguez said he was assigned to investigate Mary Agnes’ disappearance on June 10.
“This was a mystery that I, personally, just had to figure out how to solve for myself,” Rodriguez said. “Fortunately enough, this case just provided the right information needed to be solved. And it was good timing.”
Rodriguez’s work was part of Sheriff Tom Dart’s Missing Persons Project. Cmdr. Jason Moran said it focuses on cases of women who have been missing for more than three years and who appear in the National Missing and Unidentified Persons System, or NamUs.
Rodriguez and Moran said the sheriff’s office cannot confirm, definitively, that Burchard and Mary Agnes are the same person. Doing so would likely require the exhumation of Burchard and Mary Agnes’ mother, Katherine, who died in 1962, in order to see if their DNA matched.
That means Mary Agnes’ case does not fit the official criteria for removal from NamUs, which lists Mary Agnes’ case as the oldest from Illinois in an online database.
Still, Moran said he plans to explain that “the family accepts the findings and are no longer searching for Mary Moroney. So if the family is no longer searching for their missing loved one, then could we have that removed from the website?”
Dart, Rodriguez and Moran sat down with the Sun-Times this week to discuss the nearly century-old mystery, and why two families are now convinced it has been solved.
The investigation began with a search for original police reports. Rodriguez said he then began to search for members of Mary Agnes’ family. Eventually, he discovered an online forum where someone had identified themselves as a Moroney and made contact.
The detective found out that some members of the Moroney family had accounts with commercial DNA testing companies like Ancestry and 23andMe. Another member of the family agreed to also submit DNA.
Within the results of the tests, Rodriguez said he was searching for an unfamiliar person who would be listed as a Moroney relative. A granddaughter of Burchard’s, Lori Hart, was ultimately identified as a second or third cousin of the Moroneys.
Hart said Rodriguez reached out to her, and she put him in touch with Arnold, her aunt.
Arnold told the Sun-Times she didn’t initially believe the detective’s theory, but she agreed to take a test. She said her maternal grandmother’s family hailed from Poland, so she expected to see Polish DNA.
Instead, she said it showed she is mainly Irish. Not only that, but Rodriguez and Moran explained that it also revealed a genetic association with Don Moroney and his cousins, suggesting Arnold was also their cousin.
The Cook County sheriff’s office wound up sharing the findings with members of both families. However, Moran said there is no way to “responsibly investigate” the circumstances of Mary Agnes’ disappearance in 1930.
That means it may never be clear how Mary Agnes made her way from the Moroney family to the people who raised her. And what role, if any, was played by a woman named Julia Otis.
