LONDON (AFP) – The sons of a cab driver who killed 12 people in a gun rampage across rural northwestern England described him as “the nicest man you could ever meet” Sunday, adding they were baffled by his crimes.

Derrick Bird, 52, killed his twin brother David and their family's lawyer plus 10 other people and also injured 11 Wednesday.
Most of the killings came as he drove around taking pot-shots at passers-by in the sleepy county of Cumbria.
In their first public comments on the tragedy, Bird's two sons Graeme, 28, and Jamie, 16, said their father was a “loving, cheerful” man whose death had left them “devastated”.
The brothers also sent their condolences to the families of those killed by Bird.
Police confirmed Saturday that Bird was being investigated over his tax affairs, although they said they were still unsure of a motive for the killings.
A friend of Bird, Mark Cooper, said the cabbie had told him: “'They have caught me with 60,000 pounds (90,000 dollars, 70,000 euros) in the bank, the tax people'.” Cooper added: “He just said: 'I'll go to jail'.”
