What to do with a newborn fawn, its mother died?

A fawn and its mother used to hang out in our backyard often so we came to the point where we could even identify them around our area. One day we saw the mother get killed by a car running into her and now the fawn still comes into our yard, crying for its mother and I'm assuming its hungry. We don't know the exact number of weeks, just that its a little over a foot tall and we want to feed it without getting our scent because we're afraid predators might come after it. Animal Services doesn't really exist around here because they go missing/die all the time. Thank you lovelies :)
