An indictment says Keiwana Hoza Jones, 25, shook his girlfriend’s 4 1/2-month-old son so violently the child died.

The manslaughter charge resulted from one of two homicide cases reviewed by Warren County grand jurors who ended their session Thursday. In the other, jurors determined there was not enough evidence to indict a Vicksburg man accused of shooting his brother-in-law near a North Washington Street Lounge.

Jones was arrested in February and charged after an autopsy showed the infant, Matthew Parker, son of Felicia Parker, died of Shaken Baby Syndrome. Parker told authorities she woke during the night to find her son was not breathing and called for help. The baby was pronounced dead at 11:27 p.m. on Feb. 6. An autopsy later revealed the cause of the death to be Shaken Baby Syndrome.

“I’m just in shock, total shock,” Felicia Parker said earlier this year. “I keep thinking this is all a dream, that it’s not true.”

The syndrome is described as resulting in death due to swelling of the brain inside the skull after extreme shaking. Manslaughter carries a maximum 20-year sentence and doesn’t require jurors to find there was a specific intent to kill.

The father of the infant, Matthew Nash, 29, was facing a murder charge himself at the time his son died. In June, the trial of Matthew Nash ended with jurors unable to reach a verdict. Nash is among five men charged with murder in the killing of 25-year-old Justin Maurice Harris, on June 17, 2007. He remains in jail awaiting retrial.

Grand jurors, empaneled Monday, issued no bill in favor of James Ainsworth, who was arrested in the Feb. 10 shooting death of his brother-in-law, Donald Wayne Vinson, 39.

Police said Ainsworth, 24, shot Vinson following a family argument and claimed self-defense, something his lawyer affirmed.

“We clearly had evidence showing that it was self-defense,” said attorney Jerry Campbell. “We accumulated evidence and presented it to the district attorneys who then presented it to the grand jury. It was incredibly evident that the act was in self-defense.”

The deaths of the Parker infant and Vinson were the first and second homicides of the year in Vicksburg.

According to its tally, the jury heard a total of 93 cases and returned indictments in 79 of those cases. No bills were returned in 10 cases, three cases were reduced to misdemeanors, one case was dismissed and one case was referred for further investigation.
