A man who murdered a party-goer at rapper Lil Kim's 2008 birthday party was sentenced to 20 years-life in prison for the crime Tuesday. Sayed Rahman, 26, was handed the sentence after confessing to the brutal murder of Ingrid Rivera, 24, at New York City's karaoke hot spot Spotlight Live, during Kim's public bash.

Rahman, an employee of the club, helped an inebriated Rivera get back into the venue after she had been kicked out. He apparently lured the victim away from her friends to a secluded area of the club before bludgeoning her and slicing her throat. Her body was discovered two days later.

Rahman pleaded guilty to the crime in February. "I want to express my deepest sympathy to the family and friends of Ingrid Rivera," he said in a prepared statement during sentencing. "I know that I have caused them a tremendous amount of pain and suffering."

Providing no motive for the crime, it is believed that Rahman may have been on drugs at the time. Several of Rivera's family and friends assembled at the State Supreme Court in Manhattan for the sentencing. "Thank God that he's locked up -- somebody who will never be able to kill anybody else," said Rivera's mother Ingrid Estrada during sentencing. "Thank you for locking him up so he could pay for this murder."

Kim has yet to make a statement on the matter.
