A Cook County judge has sentenced Keith Cozart to 90 days in a rehab facility associated with the Cook County Department of Corrections.
Keef is 18 years old. He was sentenced to rehab after failing a random drug test ordered by the courts for an earlier traffic charge. In July, Keef was arrested for driving an excessive speed in the northern suburbs. A condition of Keef's release on those charges was that he must take random drug tests.
He failed one in September. According to his lawyer, marijuana was found in his system. Keef will next appear in court April 3.
The rapper Tweeted just after 3 p.m. "In court Finna go to Jail Judge Wants to send me Back."
The sheriff's confirmed that Cozart was back in custody and was en route to the Cook County Jail on Chicago's Southwest Side.
Cozart made his much-anticipated debut on Interscope records in December 2012 with the album "Finally Rich." He gained notoriety last year for a gloating tweet sent from his account after rival Chicago rapper Joseph "Lil Jojo" Coleman was shot to death in the Englewood neighborhood on the South Side.
The rapper was locked up in a juvenile detention center in January for wielding a gun in a music video, which violated his probation for an earlier gun conviction for pointing a weapon at police.
Cozart was arrested for disorderly conduct in May after security at the LeMeridien Atlanta Perimeter hotel "observed smoke and a smell of marijuana from a room," according to Dunwoody, Ga., police.
In July, he was ordered to pay a $531 fine after the Illionois State Police stopped him in May driving 110 miles per hour on the Edens Expressway in Northfield, according to court records.
In August, the rapper and his label, Glory Boyz Entertainment, were ordered to pay more than $230,000 to a Washington D.C.-based concert promotion company for failing to appear at a London show in December 2012, according to court records.
Cozart walked out of jail about 9 a.m. October 23 after serving nine days of a 20-day sentence, according to Cook County sheriff's office spokeswoman Sophia Ansari.
He had been in jail since Oct. 15, when he was ordered to jail for 20 days after testing positive for marijuana. Cozart received one day's credit from the sentencing judge, while receiving another 10 days credit for good behavior.
An hour after he was released, Cozart, known for his Twitter and Instagram feeds, posted a snapshot picture of a text which read "I'm back b----."
Cozart missed an Oct. 21 court date in a child support case he's involved with while in the jail, but his lawyer appeared on his behalf, Ansari said. He's scheduled for a court hearing at the Daley Center court complex in downtown Chicago on Dec. 10. The case is one of two child-support cases against Cozart.
Jasmine Woodford, the plaintiff, has accused Keef of contempt for failing to pay the full amount of child support ordered in the case. On Oct. 21, Cook County Judge Mary Trew ordered Cozart to turn over child support funds to Woodford, Ansari said.
According to the child-support suit, Cozart signed a document acknowledging he is the father of a girl born in November 2011 to Woodford.
In June, Cozart was hit with a second paternity suit. The plaintiff, 29-year-old Erica Early, claims Keef fathered her daughter, born on Jan. 28.
Cozart, who grew up in Englewood, currently lives in Northbrook.
