How long had the flat been empty? We don’t know what year it was written, do we? Could it have been earlier than 2018? I wonder if it’s possible to determine the names of those living in that flat around that time. It might be good to check again for deaths of a girl that age on or about Jan 28 for several years prior. The death wouldn’t likely have been listed as a suicide. Often news articles are discreet about that. I would definitely pass this along to LE, even at this late date. She might be listed as a missing person if she committed suicide in a secluded place, as often happens. If she is considered a missing person/runaway it would be helpful for LE (and her parents?) to know this. If this did happen in January of 2018, she would be almost 17 by now if she didn’t go through with it. What a sad note to happen upon.
