NEW ORLEANS (AP) — 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 Oliver James Montgomerywere sentenced to 20 years in prison.

New Orleans news outlets report 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.

The four ranged in age from 15 to 17 when they were charged as adults in the March 2022 killing. Authorities said Frickey died of blunt force injuries after she became entangled in a seatbelt as carjackers sped away with her car on the afternoon of March 21. She was dragged while neighbors watched helplessly.

Outside the courthouse, Frickey’s family talked with reporters about listening to statements two of the defendants made.

“When they were saying they were sorry, I’m sure they were,” said her sister, Jinny Frickey. “Because you go back, hindsight, a lot of times, you are sorry for the actions you completed. But you did it. And, unfortunately, they did it and they have to serve the time.”

One defendant wrung her hands as she stood before Frickey’s family, according to an account of the hearing in The Times-Picayune/The New Orleans Advocate. “That’s not what we set out to do,” she said tearfully of the killing, “and I hope that you all can forgive me.”

Prosecutors won’t comment until the case is over, District Attorney Jason Williams’s office said.

“However, we would like to highlight the remarkable grace of Mrs. Frickey’s family in response to the words of the three defendants who accepted responsibility for their roles in this horrific matter,” the statement said. “Our hearts and unwavering support continue to be with the Frickey family as we fight for justice and pursue a resolution that honors Linda’s memory.”
