Teed went to rob a Fforestfach post office and was surprised to find 73-year-old postmaster William Williams not only present but in a mood to resist him. The thief had brought along a hammer in case he needed to force a door or something, so he grabbed it and hammered Mr. Williams … over and over and over. Twenty-seven times. Then he rifled the station as planned while the mortally wounded old man moaned and twisted, unable to come to his feet because the floor was so slick with his own blood.
“The defence is not that this man did not kill the unfortunate postmaster,” his attorney told the jury. “That tragic fact is true. The defence is that when the accused did it he was suffering from abnormality of the mind which impaired substantially his mental responsibility for what he did when he killed the postmaster.”
After many decades when hanging was the mandatory sentence for the crime of murder (even though in practice not every murder resulted in an execution), public consternation at certain sensitive cases like those of Ruth Ellis and Derek Bentley had driven a legal reform whose intended upshot was confining the death sentence to the proverbial worst of the worst.
The Homicide Act created a new subcategory “capital murder” — especially heinous murders, such as killing a policeman or committing murder in the course of a theft. Vivian Teed went to the gallows under the latter statute.
But the Homicide Act also removed certain types of homicide from the murder category altogether — notably for Teed’s purposes, a new defense of “diminished responsibility” was explicitly authorized and defined. This defense would have saved the mentally impaired Bentley. Now Teed tried to claim that an “abnormality of the mind which impaired his mental responsibility” was what really hammered William Williams’s skull.
Only one holdout member of the jury bought this, but after a number of hours and a couple of separate attempts by the panel to declare itself deadlocked, she or he finally came around and voted to convict. Teed hanged at Swansea Prison seven weeks later.
