Daryl Linnie Mack (August 28, 1958 – April 26, 2006) was an American man who was executed in Nevada for murder. Mack was sentenced to death for the October 1988 rape and murder of Betty Jane May in Reno. The murder went unsolved for twelve years until DNA evidence linked him to the crime. He was already in jail at the time, having been sentenced to life in prison without parole for the April 1994 murder of Kim Parks. He was sentenced to death, waived his appeals and asked to be put to death. Mack was executed via lethal injection at Nevada State Prison on April 26, 2006. He remains the last person executed in Nevada.
