Rapper Petey Pablo has already started working on his three-year jail sentence since he was arrested on September 11, 2010 when he tried to smuggle a gun through an airport. The former platinum-selling rapper reportedly turned himself in to a medium security federal correction institution in West Virginia.

The 38-year-old Petey Pablo quietly started working on his jail sentence on January 4, reports say. According to the court docs, the court recommended Pablo receive “intensive substance abuse treatment, vocational training and educational opportunities” while he is behind the cold bars of prison.

Petey Pablo, real name Moses Mortimer Barrett III, was given a 35-month jail sentence on a federal gun charge. The rapper, best known for his hit songs “Raise Up” and “Freek-a-Leek,” was arrested at Raleigh-Durham International Airport when a security screener found a 9mm handgun in his hand-carry luggage. According to the authorities, they later found out that the gun was stolen during a 2005 residential burglary in Gardena, California. Petey Pablo then pleaded guilty in March for the possession of the said stolen firearm.

When he was asked about the possibility of jail time a week prior, PeteyPablo expressed hope for a positive outcome on his jail sentence. “I mean, I always feel confident,” the rapper said in an interview. “In the end, the truth always comes to the light. And, regardless of what the outcome is, I’m a man. And whatever has been written in my book of life is written in my book of life. So whatever the outcome of any situation is, I have no choice but to handle it.”

Petey Pablo is scheduled to be released on July 17, 2014 after serving his jail sentence.
