A heartbreaking incident has unfolded in Santee, San Diego, where a baby girl lost her life after being left in the back of a hot car. This tragic event occurred just two months after her adoptive parents brought her home. Is hot car death common?
Discovery and Emergency Response Into The Hot Car Death – An Ongoing Investigation
Diana Sofia Aleman Roman, the infant victim, was found unresponsive in the SUV parked outside her family’s home around 12:20 AM on June 13. The child had been left in the vehicle for several hours in 63°F weather before a family member discovered her and immediately called 911.
Despite being rushed to Sharp Grossmont Hospital, Diana could not be saved. The San Diego County Sheriff’s Office is actively investigating the circumstances that led to Diana being forgotten in the car and determining who was responsible. As of now, no charges have been filed.
The Dangers of Hot Cars – a Tragic Hot Car Death
Studies highlight the rapid rise in temperature inside a parked car. On a 70°F day, the temperature inside a car can soar to 104°F within just half an hour. Reaching 115°F in an hour. The human body’s organs begin to shut down at 107°F, making such environments lethal, especially for children.
Adoption and Family Background – A Loving Family
Diana was welcomed into the home of Romer and Jayson De Los Santos on April 11, after they traveled to Arizona to meet her in the hospital. Heartwarming photos captured the couple cradling Diana and introducing her to their two-year-old son, who was also adopted. Romer expressed his grief after the hot car death, writing, “I haven’t slept in days,” next to one of the photos.
The De Los Santos family had been actively seeking to adopt a second child, sharing their adoption profile on social media in November. They expressed their desire to provide a loving home filled with cherished memories. Special moments such as beach outings, biking to the park, and raising foster kittens. Romer, a senior consultant at Jama Software, and Jayson, a stay-at-home dad, have been together for over 20 years. They married in 2008 during a brief period when same-sex marriage was legal in California. Their home is described as a “zoo,” housing numerous pets including cats, dogs, chickens, and parakeets.
Community Reaction

Neighbors described the De Los Santos family as kind and attentive parents often seen playing outside with their children. One neighbor said, “They seem like a nice family who wanted to give a couple of kids a good life. It’s just a shame it didn’t turn out that way.” It seems many suggested that the hot car death wasn’t intentional.
Medical Examination and Broader Context

The San Diego County Medical Examiner’s Office will determine the cause and manner of Diana’s death. Annually, around 37 children die from being left in hot cars across the U.S. Since 1998, California has witnessed at least 56 such fatalities, according to statistics from San Jose State University’s No Heat Stroke project.
Preventive Measures and Legal Implications & Expert Insights
Parents are urged never to leave their children alone in vehicles, even for short periods. Temperatures can rise dangerously fast, posing severe risks to children who cannot regulate their body temperatures as efficiently as adults. Which can effectively cause hot car death. California law imposes a $100 fine for leaving a child under six in a car under hazardous conditions. With potential charges ranging from neglect to manslaughter depending on the outcome.
Experts explain that it’s possible for any parent to forget a child in a car, especially when distracted or following routine habits. The increase in such cases since the 1990s is partly attributed to the recommendation of placing child car seats in the back, out of sight to protect them from airbags.
Recommendations for Prevention
To avoid such tragedies, No Heat Stroke suggests placing a soft toy in the front seat as a reminder of the child in the back or placing essential items next to the child’s seat. They also recommend keeping vehicles locked at all times and teaching children never to play in cars.
The loss of Diana Sofia Aleman Roman serves as a stark reminder of the dangers associated with leaving children unattended in vehicles and the importance of vigilant parenting practices. Hot-car tragedies can happen to anyone due to human memory lapses.
Here are key strategies to prevent these incidents:
Create Safeguards: Establish agreements with child-care providers to notify each other if a child is absent or late. Set phone reminders to ensure the child has been dropped off.
Secure Vehicles: Always keep vehicles locked and keys out of children’s reach.
Visual Reminders: Place the child’s items, such as a diaper bag or jacket, in the front seat as a reminder.
Back-Seat Checks: Keep essential items like your backpack or briefcase in the back seat to prompt a check before leaving the car.
Never Leave Children Unattended: Never leave a child alone in a vehicle, regardless of the outside temperature.
Technological Solutions & Expert Advice:
Invest in car seats or vehicles with integrated reminder technology, such as SensorSafe. Systems that default to “on” are most effective. Use education and technology together to prevent these tragedies. Real-life experiences, like that of Jennifer Stockburger, highlight the importance of these precautions. Combining awareness with practical strategies and technology can protect children from hot-car incidents.
I WENT FOR AN ULTRASOUND AND SAW MY HUSBAND HUGGING A PREGNANT WOMAN — SO I SECRETLY FOLLOWED THEM

The ultrasound image, blurry yet undeniably real, still swam before my eyes. Two pink lines. Two tiny flickering lines that promised a future I had yearned for, a future I had almost given up on. After five years of longing, of disappointment, of tears shed in the quiet hours of the night, it was finally happening. I was pregnant.
But the joy that should have consumed me was quickly replaced by a chilling dread. As I walked out of the clinic, my eyes fell upon a scene that shattered my world. Ronald, my husband, stood in the hallway, his arms wrapped around a woman with a swollen belly. It wasn’t just a casual hug; it was a tender, intimate embrace, his hands resting gently on her burgeoning stomach.
A wave of nausea washed over me. Who was she? What was he doing here? The questions raced through my mind, each one sharper than the last. My carefully constructed world, the world I had envisioned with Ronald at the center, was crumbling before my eyes.
Gripping my purse tightly, I felt a surge of adrenaline. I couldn’t just stand there, frozen in disbelief. I had to know. I had to understand.
And so, I did something I never thought I would do. I followed them.
My heart pounded like a drum as I trailed behind them, my breath catching in my throat with every step. They walked slowly, their conversation hushed and intimate. I stayed hidden, peering through shop windows, ducking behind parked cars, feeling like a ghost in their world.
They turned down a narrow street, the houses quaint and old-fashioned. My gaze followed them to a small, two-story house with a rose bush spilling over the fence. This was it. Their destination.
I found a secluded spot across the street, my eyes glued to the window. The living room was cozy, filled with sunlight and the scent of freshly baked bread. They sat on a worn-out sofa, the pregnant woman gently stroking her belly. Ronald leaned in, his face radiating a warmth I had rarely seen directed towards me. He spoke softly, his voice filled with a tenderness that made my chest ache.
“I’m so excited, darling,” he said, his voice thick with emotion. “We’re going to be parents.”
The woman smiled, her eyes sparkling. “Me too, love. I can’t wait to meet our little one.”
“Our little one,” he repeated, the word hanging in the air.
The scene before me played out like a cruel, twisted movie. Their happiness, their shared dreams, mirrored my own, yet they were a mockery of my own hopes. I felt a wave of dizziness, the world tilting precariously on its axis.
As the afternoon wore on, I watched them. They laughed, they argued playfully, they planned for the future. I saw a love story unfold before my eyes, a love story that did not include me.
Finally, as dusk began to settle, they left the house, hand in hand. I watched them walk down the street, their silhouettes bathed in the fading light. And as they disappeared from view, I was left alone with the shattered pieces of my heart.
The walk back to my apartment was a blur. The joy of my pregnancy, the hope that had bloomed within me, felt like a distant memory. Betrayal, anger, and a deep, suffocating sadness consumed me. How could he? How could he do this to me?
That night, I cried myself to sleep, the ultrasound image of my tiny baby a bittersweet reminder of the shattered dreams. The next morning, I woke up with a resolve I didn’t know I possessed. I would not be a victim. I would fight for myself, for my baby, and for the future I had always envisioned.
The road ahead was uncertain, filled with pain and uncertainty. But I knew, deep down, that I would find my way. I would heal, I would be strong, and I would build a life for myself and my child, a life filled with love, joy, and happiness, a life that had nothing to do with him.
