'Hitmen killed wrong schoolboy,' court hears Two hitmen went to the wrong address in a fatal mix-up and stabbed a teenage schoolboy to death, a court heard yesterday. Aamir Siddiqi, 17, was attacked on his doorstep in Cardiff in April 2010. Ben Hope, 39, and Jason Richards, 38, denied charges of murder and the attempted murder of the victim's parents at Swansea Crown Court yesterday. The case continues.
