*Former NBA star Jayson Williams pleaded guilty to aggravated assault this week in the 2002 shooting death of his chauffeur, according to the New Jersey Attorney General’s Office.

Under the plea deal, Williams faces a mandatory sentence of 18 months in prison without the possibility of parole. He was scheduled to be retried on a manslaughter charge stemming from the shooting death of limousine driver Costas Christofi.

Sentencing for Williams is scheduled for February 23. Prosecutors said they will recommend five years in prison on four charges of attempting to cover up the fatal shooting. He was convicted of those charges in 2004.

Williams was tried in 2004 on eight counts, including aggravated manslaughter. A jury acquitted him of three of the more serious shooting counts, found him guilty on four “coverup” charges, and was unable to reach a decision on the second count of reckless manslaughter. The trial judge, Edward Coleman, declared a mistrial on that count, and the state decided to move forward with a retrial on that charge.

Williams is free on $250,000 bail with conditions that require him to check in daily with probation officers and not consume alcohol.

Last week, in an unrelated case, authorities charged Williams with one count each of operating a vehicle while intoxicated and operating a vehicle while impaired, the Manhattan District Attorney’s office told CNN.

Those charges allege that Williams was driving a black Mercedes sport utility vehicle fast when he hit a tree at 3:15 a.m., a New York police spokesman said. William’s bail was set at $10,000 and he was ordered by Judge Melissa Jackson to wear a monitoring bracelet.
