A paroled burglar who claimed he wanted to be a serial killer of minorities was executed Wednesday for the slaying of a mentally impaired woman who once worked with him.

Robert Neville Jr., 31, apologized to members of Amy Robinson's family as they watched from an observation room.

"I hope you can find it in yourselves to forgive me, and I hope all this here will kind of settle your pain. ... I just want you to know I am very sorry for what I have done," he said.

He added: "If I see Amy on the other side, I will tell her how much you love and miss her. And we will have a lot to talk about."

Neville and a companion were condemned for abducting Robinson as she rode her bike to the Dallas-area supermarket where all three had worked. They took her to a remote area and shot her with a rifle as she begged for her life.

Neville's companion, Michael Wayne Hall, 26, does not have an execution date.

At the time of the Feb. 15, 1998, slaying, Neville had been on parole after serving two years in prison for burglary.

Robinson, 19, was mentally impaired, according to prosecutors. She also suffered from Turner's syndrome, a chromosome disorder found only in women and characterized by short stature and lack of sexual development at puberty.

After his arrest, Neville told the Fort Worth Star-Telegram he and Hall wanted to become serial killers whose victims were minorities. Robinson was part American Indian
