Qamar David was a Pakistani Christian who was arrested on charges of insulting the Prophet Muhammad in 2006. A cosmetics supplier in Lahore, he had apparently gotten into an argument with a business competitor over text message, and he was accused of insulting the Prophet’s name during this conversation, though its content is not known. Only in February 2010, after four years of litigation and death threats, did his case actually produce a result: conviction by trial to life in prison.

"This is not a natural death ... He was fine the last time I saw him. He never informed me of any heart condition or blood pressure. This is a false story of the prison authorities." - Aslam Chaudhry, Qamar's lawyer

Though Qamar fully intended to undergo the process of appealing his verdict, he never had the chance to get far. In March 2011, he died in prison at the age of 55. The official story is that he suffered a heart attack, but neither his family nor his lawyer believe this; Qamar, they said, was a healthy man with no history of heart problems, and he had been receiving death threats. Prison authorities, on the other hand, insist that there was no evidence of murder or foul play.
