This is such a sad case; Mariam was shown on CCTV with her mum in the local Lidl supermarket at 1pm on the afternoon of 30 November 2011 but 20 minutes later she’d suffered fatal head injuries.
Although three people have been charged in connection with her death we are still actively investigating and desperately want to hear from anyone who could help.
I’m keen to understand where Miriam was, what she was doing and who she was with, in the minutes between leaving Lidl and becoming critically ill.
