Chloe had attended the swimming awards ceremony on Saturday and later went to a party at a friend's house.
Police said the cause of death was not yet known but there are not believed to be any suspicious circumstances and details have been passed to the coroner.
At about 8.30am on February 3 2013, police were called by the ambulance service who had attended a house on Bryons Drive in Timperley.
Paramedics were there to treat a 16-year-old girl who had gone into cardiac arrest.
She was taken to hospital but sadly died.
The spokesman said that Chloe had slipped and cut her lip at her friend's party, but described it as a "minor injury".
