Daryle Guillot was sentenced to 30 years in the Avoyelles Correctional Center after pleading guilty Monday to carjacking a woman in Metairie in 2013.

Guillot, who has the word “REDRUM” — “murder” spelled backward — tattooed across his forehead, was already serving a 10-year sentence for attempting to rob a woman in New Orleans with a knife.

But shortly before committing that crime, he used a jagged piece of glass to carjack a woman on Veterans Memorial Boulevard, fleeing with her 2004 Chevrolet Cavalier.

Guillot withdrew his “not guilty” plea Monday before Judge Ellen Shirer Kovach in 24th Judicial District Court in Gretna.

He also pleaded guilty to having contraband in prison, which got him another five years, although that sentence will run concurrently.

Guillot was initially sentenced to 20 years, but the sentence was increased because the carjacking was his third felony conviction. He will not be eligible for parole, probation or a suspended sentence.

Before the guilty plea, prosecutors with District Attorney Paul Connick’s office were set to point out that the car stolen from Susan Caillouet on Nov. 12, 2013, in the 200 block of Veterans was found a mile from Guillot’s apartment at 516 Marigny St., New Orleans, and 1.6 miles from the site of the attempted robbery in Orleans Parish.

Investigators said the Metairie carjacking occurred six hours before Guillot tried to rob Christena Nizialek near the intersection of Chartres and St. Philip streets.

According to a police report, Guillot blocked Nizialek’s path, pulled out a knife and said, “Give me all you got!”

Nizialek screamed and fled down Chartres toward Jackson Square. She gave police a description of Guillot, who was arrested shortly afterward when he showed up in a surveillance video.
