Please help me find my brother Rafael, missing since 2020

It has been 6 years since I last held my brother Rafael's hand. We were separated, and I have been searching ever since. The drought destroyed everything. The fields were dead and so was our hope of staying. At the time, Rafael was just 46. The separation happened because of the chaos at the border processing center in New York. I remember the way they would hum while doing chores around the house with Rafael. There was a brief call in 2022. We've heard nothing since. Rafael would be around 52 years old now. They were heavyset, with a booming laugh and gentle eyes, with a gap between the two front teeth. The not knowing is worse than any bad news could be. If anyone has any information about Rafael, please reach out. Our family will never be complete without them.
