Khalid Peshawan, 33, killed Halimah Ahmed at his Derbyshire home in 2007 before hanging himself. The health and social care Advisory Service report into Mental health Services in Derby criticised Mr Peshawans diagnosis and care.
Although the report stated there was no link between Mr Peshwan’s care the incident, it is said that mental health services failed to diagnose his condition and the care he received was inadequate.
The parents of Mr Ahmed were unhappy about the timing of the report being released on the same day as two or more relating to the treatment of people involved in other deaths in the East Midlands.
A spokeswoman for the East Midlands Health Authority has said that they chose to release the reports on the same day because they came together at a similar time.
The report highlights the care of a mentally ill women who was killed in a flat at Earl Shilton in Leicestershire in January 2006 and it found that much better communication and care in needed between medical staff and the family.
Another case that was mentioned was that of Joanne Butler who was killed by a neighbour who had not received proper mental health care and also included an inquiry into the care and treatment of mental health patient Kelvin Trenfield, 31, who stabbed neighbour Karen Godden, 50, in the head with a chisel after receiving no treatment for his illness.
