A 25-year-old Saudi Arabian air force sergeant has been sentenced to serve a mandatory 35 years in Nevada state prison for kidnapping and sexually assaulting a 13-year-old boy at a Las Vegas Strip hotel two years ago.

A judge spared Mazen Alotaibi (MAH'-zen ah-loh-TAH'-bee) additional time for lewdness, kidnapping and other convictions during sentencing Wednesday in Clark County District Court.

The victim's mother sobbed and told the judge her son's life is ruined. He's now 15.

A jury found Alotaibi guilty in October 2013 of having sex with the boy at the Circus-Circus hotel after a night of drinking cognac at a strip club on New Year's Eve 2012.

Alotaibi's lawyers argued the boy consented to sex for marijuana, and Alotaibi was too intoxicated to know he was committing a crime.
