The way police handled a rape allegation - made by Dorset teenager Gaia Pope - is to be investigated by the Independent Office for Police Conduct.
Nineteen-year-old Gaia's body was found near a cliff path close to Swanage in November last year. She had been missing for 11 days and died of hypothermia.
Her family are determined to discover if her mindset had been affected by fear over the way her rape allegation was dealt with.
Dorset Police told us they referred themselves to the IOPC and are co-operating fully with the inquiry.
