THE post mortem into the death of Lewes teenager Annie Edwards has failed to establish her cause of death.

Sussex Police said further tests have been requested after the examination was inconclusive this morning.

The 17-year-old Varndean College student died at a house in Ditchling on Friday after a party with close friends.

Her family has paid tribute to their "wonderful, happy, loving, warm-hearted, clever, mad, beautiful daughter".

In a statement, her family said: "She was at a party with close and loving friends, having a wonderful time, and at the end it seems she laid down, went to sleep, and never woke up.

They told how the former Priory school student loved music and would have taken her grade eight flute exam this year.

She was predicted to get three A grades at A-levels and had an unconditional offer from Birmingham University to study English Language and Classical Literature.

Miss Edwards died at a house in South Street, Ditchling. Emergency services were called there on Friday morning.

Police have been treating her death as “unexplained” as they await the results of the post-mortem.

Friends also paid tribute. Emma Hughes said words cannot describe “how much I love you and how much I miss you. My beautiful, wonderful friend. Forever in our hearts”.
