Darryl Littlejohn, who was convicted of murdering John Jay graduate student Imette St. Guillen three years ago, was sentenced Wednesday to life in prison without parole.

The sentencing will run consecutive to the 25 years to life he is already serving for the kidnapping of a Queens woman.

Last month, Littlejohn was convicted of kidnapping St. Guillen from a SoHo bar in 2006 and killing her. The 24-year-old's body was found in an East New York lot about a day after she was last seen.

Prosecutors used DNA, fingerprint, and fiber evidence, as well as cell phone records, to link Littlejohn to the murder.

The former nightclub bouncer did not take the stand at the trial, nor did he speak today.

Littlejohn showed no visible sign of remorse during the sentencing.

St. Guillen's mother and sister read victim impact statements in court, prior to the judge making his ruling. They explained how her untimely death affected them and why the judge should give her killer the maximum punishment.

"I understand there is no punishment that will bring Imette back and that is why there is never closure," said her sister, Alejandra St. Guillen. "I have a wonderful family and an incredible group of friends, but no one, no one replaces my little Imette, my little girl, who was with me through the hardest of times."

"I don't think there's any sentence that would be harsh enough," said Maureen St. Guillen, the victim's mother, through tears. "I leave it up to you and thank you very much."

The defense tried to blame the murder on Daniel Dorrian, the manager of the bar where St. Guillen was last seen and where Littlejohn worked as a bouncer.

In court, the judge chastised workers of that bar and asked how they could show such indifference.

Defense attorneys say they plan to appeal.
