Three years ago today at an army base in Afghanistan British soldiers came under fire from one of their own.
An Apache helicopter fired more than two hundred rounds into the compound believing it was occupied by the Taliban.
Among those on the ground that night was Lance Corporal Christopher Roney, from Sunderland. He was shot and killed in the crossfire. At an inquest earlier this year a Coroner said "mistaken beliefs and cumulative failures" among those in command led to his death.
Photographs taken days after Christopher was killed show the severity of what happened. Bullet marks can be seen on the walls of the buildings.
At the time his family thought he had been killed by the Taliban. Only at the inquest did the full horror of what happened emerge.
At the time of his death Christopher Roney had just become a father. He was only able to spend a short time with his son, William, before he was deployed.
In an exclusive interview, his wife Lorna says she will do everything in her power to make sure the youngster grows up knowing what kind of man his father was.
