PLAQUEMINE - A White Castle man who killed his wife and stepdaughter in 2007 was sentenced Wednesday to serve the rest of his life in prison.

Ervin Allen Sr., 63, was convicted May 11 of two counts of second-degree murder.

“He was mad at his wife; now he’s going to die in prison,” 18th Judicial District Attorney Ricky Ward said after the sentencing hearing.

Prosecutors said Allen left divorce court proceedings on June 12, 2007, drove to his home and shot his wife in the back of her head while she was using a computer.

After killing his wife, Allen went after his stepdaughter, Herkeshia Young, Ward said.

Allen killed the 27-year-old woman by shooting at her through a door, breaking through the door and shooting her again, Ward said.

But Allen wasn’t finished, prosecutors said. He went downstairs, retrieved a knife and then stabbed the young woman, Ward said.

Allen was upset that a judge ordered him to move out of his house at 34210 Bowie St., White Castle, after his wife, Lorna Allen, 42, filed for divorce, Ward said.

State District Judge Alvin Batiste presided over the trial and Wednesday’s sentencing.
