Hi, I hope this doesn’t seem materialistic or shallow, but this is an unresolved and still quite emotional issue for me.

My mum passed away from cancer three years ago. I’m the youngest of four, with two older brothers and one older sister. I no longer speak to my sister as of about two years ago, as she was a negative person in my life. Me and my sister went into care when I was three and she was twelve, my brothers both went to live with our nana and grandad. I went to live with my dad shortly after. My mum was a loving mum, just due to her own issues she wasn’t able to cope. I remained in contact with my family throughout my life, and was always very close to my mum. When I was seventeen she was diagnosed with lung cancer. She received treatment, but unfortunately this didn’t work and the cancer spread to her brain. She held on for a couple more weeks until she finally passed. 

My mum had a locket that my nana gave her on her 18th birthday. She wore it every day, it was her most valued possession. When she got ill she told me that when she finally passed, she wanted me to have it, which meant the world to me. However when she passed away, this locket seemed to go missing. The first person I suspected was her ex partner - they broke up in the weeks before the cancer spread to her brain and ended on bad terms, he wasn’t allowed to go to the house. However he ignored this and went to the house, and found my mum unconscious - this is when the cancer had spread. Knowing he wasn’t supposed to be at the house and that he’d be in trouble if anyone found out, he put my mum in the bath (I assume to prevent her causing any harm to herself) and left, before calling my eldest brother to tell him he couldn’t get in contact with her and that he was concerned. My brother went to Mum’s house and found her, and called an ambulance. She was taken to the hospital, where they discovered the cancer had spread. 

So first I suspected her ex.  I’d asked my sister and she was adamant she didn’t have it, and my brothers would have no reason to have it so I knew they hadn’t taken it from the word go. So of course I suspected her ex. He wasn’t a very nice person at all, he treated my mum horribly. He messaged me shortly after she passed and said some horrible things, trying to cause an argument and slated my brothers and sister. We had words and that was the end of it until a year later when I contacted him to ask if he had any photos of my mum as I didn’t have many. He sent me some, but he seemed to want to properly talk whereas I wasn’t interested in this - I had the photos and that was all I’d messaged for - still I was civil for the most part. Until once again he started saying cruel things and I lost my cool. It turned extremely nasty, we both said things. I thought that was the end of it, until. A few months later when he sent me a friend request on Facebook which I declined. He then messaged me asking if I’d gotten Mum’s locket. The fact that he’d brought it up only made me more suspicious that he’d taken it.

Anyway, I said no, that I thought he had it. He denied this and accused my brothers and sister, who I defended and accused him. He once again became nasty and said some awful things about my brothers, but also my mum (who he was claiming to love). I told him to stop messaging me and blocked him. I figured that I’d never find out what had happened to the locket and decided to let it go. 

However recently I’ve been having dreams about the locket, which had dredged it all back up. I started thinking what reason her ex boyfriend would have to have taken the locket, and started thinking that it maybe wasn’t him - he was the one who found my mum unconscious, and that was the last time he ever saw her before she was taken to the hospital and passed - he’d put her in the bath, so I can’t imagine his mindset in that moment was to take her locket. I then started thinking about my sister. 

When my mum and her partner broke up, she told my brother to take the washing machine and the TV to put in storage, because she didn’t want her ex to have them as he hadn’t paid for them and would most likely sell them. So when my mum passed, my brother took the washing machine and put it into storage as our mum had requested - but my sister took the TV for herself. I thought from the beginning that this was a pretty selfish thing to do, as she didn’t ask anyone before she did this, but it didn’t affect me so I never said anything about it. But now looking back on this, it’s possible that she would have taken the locket because she wanted it for herself (like the TV). She knew Mum wanted me to have the locket, I’d asked about it, she’d denied that the had it and I’d just taken her word for it, but now I seriously suspect that she has it - there’s just no one else. 

I messaged my brother about a week ago to ask if he knew where it was, and he said that it had been in mum’s bag at grandad’s house after she passed, but now that bag had gone missing. 

So now I knew that her ex couldn’t have taken the locket. He couldn’t have taken mum’s bag from grandad’s. My brothers wouldn’t have taken it. So I know it has to be my sister. We don’t speak and I have no interest in speaking to her ever again because of the way she was with me before we fell out, and I know that she’d never admit to having the locket. I’m honestly just so lost as to what to do, it’s all I can think about. I know to some people it’s just a locket, but it was my mum’s and it means so much to me. Does anyone have any theories or ideas from what I’ve written? I’d really appreciate hearing them. Sorry for how long this was. TIA x
