Tracking down a missing relative

Hi,

I posted a few times about my situation. My grandad was terminally ill and died on Saturday. My aunt (his daughter, mum's sister) visited about two weeks ago, maybe a week and a half ago. Think it was a Thursday.

Now none of us can get in touch with her. She's not responding to text messages or phone calls, or responding to answer phone messages. Yesterday or the day before I went to her flat, got someone to let me in, and pushed a note through her door. Her phone is still ringing which suggests it's still got battery, and after almost two weeks that probably means she's charged it at least once.

At first we were angry that she missed her dad's death and might miss his funeral, and now my mum and nana are panicking that she could be dead in the flat or in serious trouble and nobody would know.

My aunt has past history about these things. She's disappeared for a while before and just reappears after months, but I think they're particularly worried now because of the bad news she had and because it seems an odd time to just disappear. For their peace of mind more than her safety (because I'm cynical enough to presume she's drunk in a ditch somewhere) I want to track her down.

Any suggestions?
I'm going to drop in at her flat tomorrow morning around 9 and ask the residents politely if they've seen or heard her coming and going at all. I'll try her flat again if I can get in there.

As a long shot, just in case she really is in trouble, I'm going to call the hospital and police to see if they've had any dealings with her. Beyond that, I'm stuck. She lives about four miles away but I don't know any of her friends, and she doesn't work either. All I know is that a child in Year 11 at a local school calls her "aunty" because his mum is best friends with her, but I don't know her name and I don't think I can just stroll into a school and ask to see the kid for that reason...
