HUNTSVILLE, Texas (AP) _ Family members of the victims of a serial killer had little sympathy for his execution-room pleas, expressing satisfaction after the one-eyed radiator repairman died by injection.

Ricky Lee Green, 36, was pronounced dead Wednesday, seven minutes after the drugs were administered.

``Now we can go on and not have to worry about him getting out and hurting anyone else,'' said Shirley Bailey, whose sister was killed by Green.

Green was condemned for the Dec. 27, 1986, death of Steven Fefferman, an advertising executive with Fort Worth television station KXAS.

Fefferman, 28, was castrated and repeatedly stabbed with a butcher knife at his home after he and Green had sex, according to testimony at Green's trial. He also admitted killing three people in 1985, including a 16-year-old boy who was castrated and stabbed like Fefferman.

Speaking quietly and slowly, Green turned to four relatives of his victims, who watched through a window a few feet away, and said he was sorry.

``This to me is another killing and it's not going to solve nothing,'' he said. ``I feel my punishment is over and now my friends and family are being punished.''

Lee Fefferman, the victim's mother, referred to Green as a ``heinous monster'' and thanked the state ``for its courage in ridding society of those fiends who take another's life for the thrill of it...''

Green had been sentenced to life prison terms for two other killings.

``He's real cold,'' said former Fort Worth police Detective Danny LaRue. ``When I finally got through with the confessions and asked him why he killed these people, his reply was: `They all deserved it. They were kind of the dregs of society.'''

LaRue said eight other unsolved murders in North Texas bear Green's trademarks.

The execution was the 31st this year in Texas, adding to what already is a record year for capital punishment in the state. Nationally, Green was the 58th condemned killer put to death this year, the most active year for executions in the United States since 1957, when 65 took place.
