Mum never got over injecting son with infected blood

Euan got a settlement payment of £20,000 in 1993, which he wanted to spend on a motorhome.

But at the dealership there was a boat that caught his eye, and he said, “I want that boat”.

So they bought a 29ft boat and the next day it was in the water at the marina at Cameron House on Loch Lomond.

John says it gave Euan a huge amount of joy. He named it Butterfly 23, after the needles used for his many intravenous drips.

“The first time we came down, I drove the boat out to the bottom of the loch and then Euan pushed me out of the way and he said, ‘Let’s see what this baby can do’,” he says.

Euan took over the wheel and the boat planed up out of the water, and for 26 miles it flew up to the top of Loch Lomond and back down again, overtaking the traffic on the A82 on the shore.

“He loved it, absolutely loved it,” John says.

“The last time they were on the boat was on his last birthday in June 1993 when he was 16.

“All his pals were there on the boat, and it was a fantastic party. But after that he was too ill to go back.”

Euan died seven months later, on 12 January 1994.
