The accused gunman in a fatal shooting near Clay Street and Mission 66 has pleaded guilty to manslaughter.

Another suspect in a separate weapons case also pleaded guilty the same day.

In the homicide, Lance Maniel, 25, 195 Countryside Drive, had been charged with murder in the Aug. 14 fatal shooting of 22-year-old Jarvis Donald, 2607 Pearl St.

The plea to the reduced charge was entered Friday before Judge Frank Vollor in Warren County Circuit Court. Maniel’s trial had been set to start Monday.

The plea was entered with no deal. Vollor ordered that the Mississippi Department of Corrections prepare a presentencing report.

No sentencing date was set.

The maximum sentence for manslaughter is 20 years. A conviction on a murder charge carries a mandatory life sentence.

Donald was shot about 7:18 p.m. Aug. 14, a Sunday, as he was sitting in his car near Jubilee Exxon, 1215 Mission 66, police said. After Donald was shot, his car rolled across Clay and struck a pole, where it came to rest, police added.

About 5 1/2 hours later Maniel turned himself in to police. He was charged with aggravated assault until Donald died the next morning at University Medical Center in Jackson.

Police, at the time, said they had determined no motive in the killing.

District Attorney Gil Martin said Monday that the two men were members of separate groups that had been engaged in an ongoing dispute.

&#8220They had been arguing back-and-forth over a period of days,” Martin said.

Maniel remained in the Warren County Jail, where he had been since his arrest.

The second case was that of Tremaine Williams, 21, 1900 Baldwin Ferry Road, Apt. 10B. He pleaded guilty to gunfire a month earlier and within about a mile of the Clay and Mission intersection.

Williams was sentenced to eight years in prison with six to serve for firing several shots at a 36-year-old Clay Street resident and for possessing a weapon, a 9-mm handgun, as a convicted felon. The intended victim ran from the scene at Clay and First North streets and was not hit. Williams also pleaded guilty to the weapon charge and was sentenced to two years in prison, to run consecutively with a prison sentence in the other case.

Williams also had pending a charge of possessing cocaine on Feb. 15, 2004. On that conviction he received a six-year sentence with four to serve.

Vollor further ordered Williams to serve three years’ post-release supervision.

Martin said authorities did not believe the two shootings were related.

Police are still seeking a suspect in a similar case, the July 17 shooting death of David W. &#8220Jones” Anderson, 41, 4719 Gibson Road, outside the Elks Lodge, 2916 Walnut St. A companion was also wounded in that case.

Crimestoppers and family members of Anderson have both offered rewards for information about Anderson’s death.
