HUNTSVILLE, Texas (AP) _ A man was executed by injection Tuesday for fatally shooting a laundry clerk when he was 17.

Glen Alan McGinnis was convicted of shooting 30-year-old Leta Ann Wilkerson in the head, shoulders and back while stealing $140.

The Vatican, the European Union, the American Bar Association and a collection of anti-death penalty groups pleaded for the life of McGinnis, 27, because he was a juvenile when he killed Ms. Wilkerson in 1990.

McGinnis said in a recent interview that he didn't want to use his difficult childhood as an excuse for his crime.

After his father abandoned him, the young man lived in a one-bedroom apartment with a mother who traded sex for crack cocaine. McGinnis was raped as a child and beaten with an extension cord.

McGinnis' execution was the sixth this year in Texas. He was the eighth juvenile offender executed in Texas since capital punishment resumed in the 1970s.
