Harrow killing blamed on school drug culture
The father of a young fashion designer stabbed to death by a former pupil of Harrow school who went on to Oxford University yesterday blamed both institutions for failing to tackle the "despicable" drug culture that drove the student to kill. (emphasis mine)

William Jaggs stabbed Lucy Braham 66 times in a "ferocious and unrelenting" sexually-motivated attack at her home in north London. She was stabbed more than 16 times on the arms and hands as she tried to defend herself. Jaggs stabbed her 12 times in the chest. After she collapsed face down on the floor in the kitchen, he stabbed her 33 times in the back. The killer then tried to carve her torso with a saw, and used a pair of garden secateurs to attempt to chop off her thumb. When officers arrived Jaggs was standing over the body, holding the knife towards them. He then stabbed himself 32 times and required emergency surgery.
Let's dig a little deeper:
The Old Bailey heard that 23-year-old Jaggs became a drug user at Harrow school, where his father was a teacher.

One pyschiatrist said that tests carried out after the killing showed he was showing early signs of mental disorder and "severe emotional disturbance" from the age of 14. The court heard that Jaggs had visited a GP in Oxford, who gave him prescription drugs after he complained of being depressed. But the doctor failed to diagnose the signs of schizophrenia.

Jaggs pleaded not guilty to murder but admitted manslaughter on the grounds of diminished responsibility. The judge, Mr Justice Bean, told him he might never be released and said doctors had described him as dangerous, and a grave and immediate risk to others. Jaggs, who was judged by psychiatrists to be suffering from schizophrenia, was sent to Broadmoor secure hospital indefinitely.
But the headline - 'Undiagnosed schizophrenic kills young woman and then attempts to take own life' doesn't appeal as much to The Telegraph as 'Drug crazed old Harrovian/Oxford student in murderous sex assault'.
