Clarence Ray Allen

Clarence Ray Allen (16 January 1930 – 17 January 2006) was an American murderer who was executed by lethal injection at San Quentin State Prison in California for the murders of three people. At age 76 in 2006, he became the second-oldest inmate to be executed in the United States since 1976, after John B. Nixon of Mississippi who was executed in December 2005 at age 77. His execution was the most recent one to take place in California.

Pro-death penalty activists cite Allen's actions as a reason to support capital punishment in the United States. He was already serving a life sentence for one murder when he was convicted of organizing the killing of three more people.

While in prison, Allen claimed Choctaw heritage. He also claimed to be deaf, blind and severely disabled, requiring a wheelchair for mobility. He did not know any sign language to communicate with hearing people. During his execution, he was able to walk from his wheelchair to the death podium unassisted. In addition, he appeared to be looking straight at his family prior to receiving the first dose of drugs during his lethal injection procedure. Allen had a confirmed advanced case of type 2 diabetes, and he suffered a perhaps related heart attack on September 2, 2005. His lawyers declared that "he presents absolutely no danger at this point, as incapacitated as he is. There's no legitimate state purpose served by executing him. It would be gratuitous punishment." They argued that his execution would constitute cruel and unusual punishment and requested that he be granted clemency by California governor Arnold Schwarzenegger, which was subsequently refused.
