Rapper Sean Kingston has been sentenced to three and a half years in federal prison after being found guilty of wire fraud alongside his mother, Janice Turner.

According to NBC news, Kingston, 35, and Turner, 63, were convicted in May of defrauding luxury businesses of more than US$1 million through fraudulent wire transfers. Turner received a five-year sentence last month.

During Friday’s sentencing, Kingston’s attorney argued that the entertainer’s actions were influenced by trauma from a 2011 jet ski accident and the absence of role models during his rise to fame. Prosecutors rejected that defence, calling Kingston “a thief through and through” and pushing for a longer sentence.

Kingston, whose real name is Kisean Anderson, briefly addressed the court, saying, “I’ve learned from my actions.” He was remanded immediately after sentencing. A restitution hearing is scheduled for October 16.

Authorities said Kingston and Turner used his celebrity status to obtain jewelry, luxury cars, furniture, and electronics without paying, in a scheme that lasted several years.
