Daryl Linnie Mack (August 28, 1958 – April 26, 2006)[1] was an American man who was executed in Nevada for murder.

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.

[4] On October 28, 1988, the body of 55-year-old Betty Jane May was found in her basement room at a boarding house in Reno, Nevada.

[6] On April 8, 1994, the body of 35-year-old Kim Parks was found in a motel room in Reno by a maid.

He originally denied ever being at the motel, but the DNA evidence obtained from the bed sheet matched his.

[10] While Mack was in prison, the unsolved homicide of Betty Jane May was reexamined by another detective who requested DNA testing of some of the evidence.

Semen that had been taken from May's body as well as blood stains found on her blouse matched the DNA profile of Mack.

His execution was originally scheduled to be carried out on March 5, 2004,[16] but it was put on hold until the court resolved his legal appeals.

"[21] Mack is the first and only African-American man to be executed by the state of Nevada since capital punishment was reinstated in 1976.

[27] In 2021, convicted mass murderer Zane Floyd was scheduled for execution in Nevada on July 26, 2021.
