Sad, but knowing how strange society is, there's actually a decent chance she'll find that out of production can of juice. Due to collectors, hoarders, forgetful people, and those who recreate classics so faithfully it's impossible to tell the difference. There are so many stories of people finding 50 years old consumables in odd place, like abandoned houses, in an old fridge in a warehouse, storage units people have almost forgotten about, etc.
Plus, people investigating a constantly wandering robot who do their due diligence and research her owner could easily find out he's dead and get her turned in to the robotics company. Or it might blow up as a viral news story and somebody could "adopt" her and let her keep the memories, but encrypted or something.
