A judge has called Danilo Restivo a 'cold, depraved and calculating killer', as he sentenced him today to life behind bars for the murder of Heather Barnett.

The thirty-nine year old Italian has been told he will never be released from prison.

Mum of two Heather was killed and mutilated at her Charminster flat in 2002, and, Mister Justice Burnett said, deliberately left to be found by her two children.
