In page Volunteer (capital punishment):

"

Since the 1976 reinstatement of capital punishment in the United States, there have been at least 150 documented cases of execution volunteers. The first documented case since 1976 was of Gary Gilmore in 1977 who "withdrew his rights of appeal from Utah’s legal system and requested that the courts enforce his death sentence as soon as possible".[1] A notable, recurring pathology of criminals requesting execution is serial killers, including Westley Allan Dodd and Michael Bruce Ross.[citation needed]
