How Advanced DNA Technology Solved a Heartbreaking Cold Case
In an extraordinary turn of events, Andrea Michelle Reyes, a child abducted from New Haven, Connecticut, in 1999, has been found alive in Mexico after 25 years. The story of her disappearance and eventual discovery is a testament to the power of persistence, hope, and cutting-edge forensic science.

The Abduction: A Parent’s Worst Nightmare
In October 1999, 23-month-old Andrea Michelle Reyes was abducted from her home in New Haven by her non-custodial parent, Rosa Tenorio. The disappearance shattered her father’s world, but he never gave up hope. For over two decades, he tirelessly searched for his daughter, keeping her case alive in the National Missing and Unidentified Persons System (NamUs).
The New Haven Police Department, along with other agencies, investigated the kidnapping, but for years, the case remained unsolved. That all changed in 2023, when a breakthrough finally arrived.
The Breakthrough: A Daughter’s Call and a DNA Match
Earlier this year, Andrea Michelle Reyes, now 27, reached out to her father, sparking a renewed investigation. Authorities turned to Othram, a Texas-based forensic laboratory specializing in advanced DNA techniques, to confirm her identity.
Reyes provided a DNA sample, which was compared to her father’s DNA profile. The results were conclusive: the woman claiming to be Reyes was indeed the child who had been kidnapped over two decades ago.
Investigators believe Reyes was taken to Puebla, Mexico, where she has lived for the past 25 years. The details of her life during this time remain unclear, but her discovery has brought closure to a case that haunted her family and the New Haven community.
The Role of Forensic Science in Solving Cold Cases
Kristen Mittelman, Chief Development Officer for Othram, emphasized the importance of their work in cases like this. “Whether it is unidentified human remains, the identity of a suspect in a crime, or, like in this case, confirming the identity of a woman who has been missing for decades, we do the same thing every day – we find answers for families,” Mittelman said.
Othram’s cutting-edge forensic technology has been instrumental in solving numerous cold cases, offering hope to families who have waited years, or even decades, for answers. This case is a powerful example of how science and determination can come together to achieve the seemingly impossible.
A Community’s Relief and Reflection
The news of Reyes’ discovery has brought relief and joy to her family and the New Haven community. For her father, the decades-long search is finally over, and he can now reunite with the daughter he thought he had lost forever.
This story also serves as a reminder of the countless families still waiting for answers about their missing loved ones. It highlights the importance of never giving up and the potential for modern technology to bring closure to even the most heartbreaking cases.
Why This Story Matters
The discovery of Andrea Michelle Reyes is more than just a feel-good story – it’s a powerful reminder of the resilience of the human spirit and the incredible advancements in forensic science. It also underscores the importance of keeping hope alive, no matter how long it takes.
For families with missing loved ones, this case is a beacon of hope. It shows that even after 25 years, answers are possible, and reunions can happen.
