Giant swastikas drawn in the snow on the hood of my car

This has happened 3 times already. My car stays outside (on the street parking) overnight. It is the only car they do this amongst many others (they could also do). My boyfriend is a Jew. We just arrived in the country a month ago, we live and work at a tiny village high up in the mountains. We are scared and don’t know what this means… or what could happen. We suspect is someone from work who knows he’s a Jew, and also knows which one is my car. I’m going to try to check for street camera footage, but don’t even know where to start…. Tips?
