Road rage murder

There seems to be a spree of random serial killers and murderers lately going ballistic on other people.
A Matthew Daley (35) killed the person who crashed in the back of his car, a Donald Lock, aged 75, by putting a knife through the retired man with no less than...39 stabs.

I get it it's pretty annoying getting in a car accident out of the blue.

Apparently Daley had mental health problems that drove him to commitic homicide. He's been deemed unfit to be tried in court and was sent to an institution.
The victim's family is perfectly satisfied with the fact that Daley is being treated for his mental illness, and they are suing the NHS (UK public healthcare system) for failing to provide the best care for their loved one.
