The man known as the DC sniper has been executed for the October 2002 killings of ten people in DC, Virginia and Maryland. John Allen Muhammad was killed by lethal injection Tuesday after Virginia Governor Timothy Kaine denied a last-minute appeal for clemency. Larry Traylor of the Virginia Department of Corrections announced Muhammad’s execution.

Larry Traylor: “The execution of John Allen Muhammad has been carried out under the laws of the Commonwealth of Virginia. Death was pronounced at 9:11 p.m. There were no complications. Mr. Muhammad was asked if he wished to make a last statement. He did not acknowledge this or make any statement whatsoever.”

Defense attorneys had argued for sparing Muhammad’s life on grounds he suffered mental illness worsened by the Gulf War syndrome he developed while serving in the first US invasion of Iraq.
