Have you seen Mario? Separated at the border in 1996

It has been 30 years since I last held my sister Mario's hand. We were separated, and I have been searching ever since. After years of struggling to make ends meet, the decision to leave was made. Mario had just turned 47 when it happened. We were caught up in the chaos at the border processing center in Phoenix. I remember staying up late telling stories by flashlight when the power went out with Mario. The last time we heard anything was 2025. Every lead has gone cold. Mario would be around 77 years old now. They were compact build, thick eyebrows, always well-groomed, with a gap between the two front teeth. Not a day goes by when I don't think about them. If anyone has any information about Mario, please reach out. Our family will never be complete without them.
