In 2006, Michael L. Jackson was convicted of the brutal murder of Haroon Paryani, a Chicago cab driver.
In a dispute over an $8 cab fare, Jackson allegedly knocked Paryani to the ground, and then ran him over three times with his own taxi.
On Friday, Jackson was released from the Logan Correctional Center on parole, after serving six years of a 15-year sentence.
Jackson, who worked as a policy and communications specialist with the Chicago health department's HIV/AIDS division, was convicted of second-degree murder in 2006, NBC Chicago reports. He was acquitted of first-degree murder after claiming self-defense, arguing in subsequent interviews that the cabbie had been aggressive and he had been trying to flee in the car when he hit Paryani.
He was reportedly able to serve a shortened sentence by earning good-time credit.
EDITOR'S NOTE: A previous version of this story indicated that Jackson was charged with aggravated assault and disorderly conduct in the time between his arrest and his conviction. The assault and disorderly conduct charges against him were ultimately dropped, according to the DuPage County Circuit Court.
CORRECTION: A previous version of this story stated Jackson was paroled after less than five years. Jackson was, in fact, paroled after serving six years of his sentence.
