Please help me find my son Ngozi, last known to be in London

I've been looking for my son Ngozi since 2017. This platform is my latest attempt to bridge the gap that opened when they left. Ethnic tensions in our region made it dangerous to stay. Ngozi, then 45, left with the blessing of the whole family. For the first 17 months, we received occasional calls. Ngozi was working in landscaping in London and seemed to be doing okay. They talked about sending money home, about eventually bringing us over. A friend saw them around 2023. We tried everything — calling mutual friends, reaching out to the diaspora community — but no one had recent news. I remember walking to school together every morning, rain or shine with Ngozi. Those are the memories I hold onto. Ngozi would be around 54 today. about 5'8", medium build, with dark hair and brown eyes. The holidays are the hardest — their empty chair at the table speaks volumes. Please, if you know anything about Ngozi, reach out. Our family back home is waiting.
