Richard Moore on death row for 'slaughter of clerks' executed by lethal injection

The U.S. state of South Carolina executed Richard Moore, who was convicted of killing a convenience store clerk.

At 6:24 p.m. local time on the 1st, 59-year-old Richard Moore, who was sentenced to death in 2001 and was serving in a South Carolina prison, was executed, the Associated Press reported.

The death penalty was carried out in the form of injecting poison with syringes, the South Carolina Department of Corrections explained.

Moore was sentenced to death in September 1999 for shooting and killing a clerk during a robbery at a convenience store in Spartanburg County.

Moore entered the store unarmed at the time, but when the clerk pulled out his gun, he took it and shot it.

Moore's lawyers asked for a commutation to life in prison, saying he had continued his exemplary incarceration, but it was not accepted.
