The trial for Brittany D. Kelly, a 16-year-old charged with her mother’s September murder, has been postponed because the prosecution needs more time.

In November, a grand jury indicted Kelly for the murder of Jacquelyn Thompson, 35, who died from a gunshot wound to the head at her Proby Road house.

The trial was scheduled to begin Thursday, but Judge Forrest “Al” Johnson granted a motion for continuance Monday, which will postpone the trial.

District Attorney Ronnie Harper filed the motion Wednesday, which said neither he nor the defendant had received a copy of the autopsy report.

“It has turned out to be a little more difficult to obtain information than we originally thought,” Harper said at the motion hearing Monday.

He said he had requested crime lab reports, as well as the autopsy results.

“And there may be some other things that need to be made available,” Harper said.

He would not comment on why the paperwork was taking so long to obtain.

Kelly’s attorney, Joe Hollomon of Jackson, opposed the motion and to the delay.

“On behalf of my client, I object,” Hollomon said. “The trial is weighing unnecessarily on her family.”

Johnson said that since Kelly was out on bond — $120,000 — he had few qualms about granting a continuance.

He ordered the two attorneys to exchange information and “confer on a new trial date.”

Kelly’s scheduled trial date Thursday came on the heels of another murder trial that ended March 15.

The timeline between Kelly’s indictment and the trial date was relatively short, Harper said after the hearing.

“She was just indicted in November,” Harper said. “Very few cases of this magnitude go to trial that quickly.”

Johnson’s next session is scheduled for July, so that will likely be the earliest a trial date would be set, Harper said.
