Please help me find my grandfather Hector, missing since 2020

My grandfather Hector and I were separated in 2020 during what was supposed to be a routine stop near Tucson. That was the last time I saw them. We joined the caravan hoping for safety in numbers. Hector was 11 years old at the time. The separation happened because of a raid on the workplace in Tucson. I remember Sunday mornings when the whole family would cook together with Hector. The phone number stopped working around 2022. After that, nothing. Hector would be around 17 years old now. They were short and stocky, with a round face and kind eyes, with always wore a silver chain necklace. The holidays are the hardest — their empty chair at the table speaks volumes. If anyone has any information about Hector, please reach out. Any detail, no matter how small, could bring us back together.
