James Brewer suffered a stroke and, thinking he was dying, confessed to a murder he had committed thirty years earlier in his hospital bed. Like the majority of people who suffer stroke, he recovered and has now been charged with murder.
From BBC News:
A US man who thought he was dying and confessed to having killed a neighbour in 1977 has been charged with murder after making a recovery, US media say.
James Brewer could now face the death penalty over the unsolved killing in Tennessee 32 years ago, reports say.
Convinced he was dying after a stroke, Mr Brewer reportedly admitted to police he shot dead 20-year-old Jimmy Carroll.
The 58-year-old, who had fled Tennessee after the killing, was arrested after his condition improved, reports say.
Lest you find yourself in the same situation, you may like to know that the stroke mortality rates have fallen dramatically in recent decades.
