3 teen girls plead guilty in carjacking, dragging death of 73-year-old New Orleans woman: "I hope that you all can forgive me"

Three teenage girls involved in the dragging death of a woman whose arm was severed during a carjacking in New Orleans last year pleaded guilty Monday to reduced charges and were sentenced to 20 years in prison.

CBS affiliate WWL-TV reports that the three were convicted of attempted manslaughter in the death of Linda Frickey, 73. A fourth suspect, a male who is now 18, still faces a second-degree murder charge, which carries a life sentence.

All four had been slated for trial Monday. Jury selection for the lone remaining suspect, who prosecutors said was behind the wheel when Frickey died, got underway after the three girls' guilty pleas were entered.
