Henderson County District Attorney Mark Hall is preparing for the capital-murder trial of Sarah Henderson the Payne Springs mother accused of killing her two daughters.

According to court records Henderson will go on trial Aug. 5.

Because of the size of the jury pool, jury selection will be held at the Texas Freshwater Fisheries Center. District Attorney Mark Hall has said 392nd Judicial District Judge Scott McKee will conduct voir dire on July 30. Voir dire is a preliminary examination of prospective jurors.

“During this time, Judge McKee will explain to the possible jurors what qualifications will be needed to serve on the jury, such as whether the juror is a Henderson County resident or if the juror has any felony convictions. If a person is over 70 years old, they can opt out of jury duty or if they have children without supervision.”

On Aug. 5 Hall and Henderson's defense attorneys Steve Green and John Scott, will question each potential juror individually. The process is expected to take a couple of weeks.

Henderson, 31, pleaded not guilty after being indicted in January 2018 on two counts of capital murder, attempted murder and assault on a public servant.  She remains in the Henderson County jail on a $2.1 million bond.

She was arrested on Nov. 2, 2017, at her Payne Springs home. Henderson County Sheriff Botie Hillhouse said at the time she had planned the murders of Kaylee and Kenlie for a couple of weeks and that she tried to kill her husband, Jacob Henderson, before the gun malfunctioned. The girls were 5 and 7 years old.

“The assault on a public servant arose two days later while Henderson was being held in the Henderson County jail, where she is accused of striking a detention officer while he was attempting to release her from restraint,” according to reports.

According to Hall this is only the second death penalty cased tried in Henderson County in recent history.

A pretrial hearing will be held on June 11 to hear motions made by the defense attorneys and the prosecutors for the State of Texas.

Hall will take the lead for the prosecution and Assistant District Attorney Nancy Rumar will take second chair.

The trial that is expected to last a few weeks will be held at the Judicial Complex in Judge McKee's courtroom and is open to the public.

McKee has place a gag order on the Henderson's trial making it illegal for attorneys to discuss information regarding the upcoming murder trial.
