Missing teen: Police working to understand last Tweet

Police say they are working with the siblings of missing teenager Georgia Williams to try and understand what the last Tweet she sent may have meant.

The message on Twitter was sent on the 26th May at 10.30am just nine hours before she went missing. In the message she wrote that she had 'stuff on her mind' and could not sleep.

The 17-year-old former Head Girl has two sisters, both of which are currently working with police to try and understand what may have been preoccupying her when she posted the message.
