Clark, 45, from Roswell, New Mexico, died in the state prison here. Just before dying, Clark said: «I will be with God in 15 minutes.»
Clark was condemned to death in 1986, accused of raping and killing Dena Lynn Gore, a 9-year-old girl from Artesia. Dena´s parents were present at the execution.
Archbishop Michael Sheehan of Santa Fe, as well as other bishops of New Mexico, had appealed for clemency for Clark, but Republican Governor Gary Johnson and the state´s Supreme Court rejected their appeals.
