William Barnard's mental health carers 'missed opportunities'
Health workers missed vital chances to assess the state of mind of a man who later killed his grandfather, a report has concluded.
William Barnard, 32, stabbed John McGrath, 81, in July 2009.
Barnard was found guilty of manslaughter and is now detained in Rampton high security hospital.
The findings have been published following an independent investigation for the East Midlands Strategic Health Authority.
