A bloke named Terry Cottle, father of four and married to Cheryl, shot himself.
He was put on a life support machine but there was no hope. His family gave permission for his organs to be used and so his heart went to a man named Sonny Graham who was on the transplant list as he had heart failure.
Sonny, through an agency,wrote to the Cottle family to express his thanks as the heart had effectively saved his life. He ended up meeting up with Cheryl, they fell in love, got married and then ..... he went and shot himself
