A special session jury trial has been scheduled in Pottawatomie County District Court this summer for the defendant charged in the murder of Tecumseh Police Officer Justin Terney.

Byron James Shepard, 36, is charged with first-degree murder in the officer's death that occurred in March 2017.

Shepard, who is jailed without bond in the Pottawatomie County Public Safety Center, now has a jury trial date scheduled to begin June 18 during the special session jury term.

District Attorney Richard Smothermon also has filed a Bill of Particulars seeking the death penalty in this case.

In that filing, he said Shepard meets five of eight aggravating circumstances that warrant the death penalty, including having previous felony convictions, committing a murder to avoid arrest, being a threat to society and the fact that Terney was a peace officer in the performance of his duties.

Officer Terney, 22, died March 27, 2017 from gunshot wounds he suffered in an alleged shootout with Shepard, a passenger who allegedly fled from a traffic stop.

The driver of the vehicle in that stop, Brooklyn Danielle Williams, 23, is charged with second-degree murder. She also has pleaded not guilty and her next court date is scheduled Feb. 27.

Shepard is accused of causing the death of Officer Terney by inflicting mortal wounds when firing a Springfield XD semi-automatic 9 mm pistol into the abdomen and leg of the officer during the traffic stop.

Terney's dash cam video captured the traffic stop before Shepard fled, then audio of events and gunshots going on in the nearby treeline.

In addition to the murder charge, Shepard also faces charges of knowingly concealing stolen property relating to the stolen firearm used in the homicide, along with a charge of possession of controlled dangerous substance, methamphetamine, which officers found on his person that night en route to the hospital.
