Gunman 'going mad' before rampage
Horrific details of Derrick Bird's ruthless killing spree have been revealed for the first time at the inquest into the deaths of his 12 victims.
The taxi driver, 52, began his murders by blasting his semi-naked twin brother David in his bedroom, shooting him 11 times.
Days before, David told his estranged wife Susan that his brother was "going mad" and needed to be sectioned, the Workington inquest heard.
He was worried about a tax investigation involving up to £60,000 of income, some of which was not declared, and feared he would be sent to jail.
And Derrick's son, Graeme told how his father was "not his normal self", worried and holding his head in his hands in despair the day before the murders.
Relatives of the dead held hands to their faces as the full horror of the taxi-driver's rampage through West Cumbria was revealed for the first time.
During the murders on June 2 last year, Bird, 52, carrying a 12-bore sawn-off shotgun and a .22 rifle, had repeatedly stopped his Citroen Picasso car, called victims over as if to ask the time or for directions, then blasted them in the face with a shotgun.
On more than one occasion he left his vehicle, changed his weapon to the rifle, and finished off his victims by shooting them in the head at point blank range.
Graeme Bird, 29, said his father was "not his normal self" the day before the shootings and was worried he was being "set up" to go to jail.
He said his father did not appear worried when he previously mentioned his tax investigation but when visiting his home on June 1 last year he "sat on the sofa with his head on his hands".
