Looking for Oscar — lost during border crossing 2023

Oscar, my aunt, was taken from our family in 2023 near Phoenix. We have spent every day since trying to find any trace. Violence in our hometown made staying impossible. Oscar was 4 years old at the time. We were caught up in the sudden deportation order carried out in Phoenix. What I miss most is walking to school together every morning, rain or shine. Someone who knew them mentioned seeing them in 2023. We've heard nothing since. Oscar would be around 7 years old now. Last I saw them, they were medium height, athletic build, with a distinctive walk. My children ask about them, and I don't have answers to give. If anyone has any information about Oscar, please reach out. Our family will never be complete without them.
