A 'devious' drug addict who savagely murdered her mother 'in cold blood' and then tried to cover up the killing must serve at least 17 years in jail.
Cassandra Scott, 36, stabbed her mother Beverley 10 times in a crack cocaine fuelled rage, then left her body in the house they shared for two-and-a-half months.
Beverley, 58, had previously told police she was 'terrified' of her daughter and scared of her temper.
