I dunno if this helps, but the Philadelphia hotel in which she died is probably The Windsor Suites, going by the appearance of the carpet and door in her TikTok videos and druggy pic. But tere is the possibility that she stayed at another cheaper seedier hotel -- what is certain is that she had walked past Russell Byers Charter School on the night of Feb 6, as she posted a Tiktok video of herself dancing in front of the building with its distinctive red awning over the entrance.

The embedded timestamp of her last public TikTok video https://www.tiktok.com/@grubage/video/6790802504029359365 is 2020-02-07 20:21:57 UTC i.e. February 7 16:21:57/4.21pm Eastern Time, the afternoon before her death, but iirc her actual last Tiktok video is set to be only viewable by mutuals. I'd only need the URL to find the timestamp tho [Embed]
