Searching for my father Juan, separated at the US border in 2018

My father Juan and I were separated in 2018 during what was supposed to be a routine stop near New York. That was the last time I saw them. We had been living peacefully for years when everything changed overnight. Juan had just turned 4 when it happened. The separation happened because of a traffic stop that turned into a detention in New York. What I miss most is the way they would hum while doing chores around the house. The phone number stopped working around 2018. Since then, complete silence. Juan would be around 12 years old now. Last I saw them, they were tall for the family, around 5'10", with an easy grin. I've never stopped looking. I never will. If anyone has any information about Juan, please reach out. Even knowing they are alive would mean everything.
