Brad Miller, then 49, fatally shot 19-year-old Christian Taylor early on Aug. 7 while responding to a burglary alarm at Classic Buick GMC near Interstate 20 and Collins Street. Miller went into the showroom alone and followed Taylor through the building.

Police said that after Taylor was acting erratically and began to “rapidly approach” Miller while cursing. As Taylor continued to advance, Miller fired at the unarmed teenager.

In a letter to the DA, Taylor’s attorney, Michael P. Heiskell, expressed sadness and disappointment by the decision of a Grand Jury to issue a no-bill in their consideration of Miller’s conduct.

The letter reads in part:

“We are now requesting that you authorize charges be filed against Miller for either Voluntary Manslaughter or, at the very least, Criminal Negligent Homicide.”

Heiskell’s letter also states that Taylor was “exhibiting psychosis as a result of the synthetically-laced marijuana he had previously smoked.”

The letter calls into question Miller’s “unilateral decision to break protocol and move away from fellow officers.” Heiskell communicated his belief that the “compelling evidence” warrants a “second look.”

Heiskell’s letter also mentions what it refers to as a “similar no-bill” in the matter of Ed McIver, Jr. who was accused of shooting Fort Worth Officer Matthew Pearce. It reminds Wilson that her decision to file charges would not invoke double jeopardy and even mentions the fact that “unlike McIver, Miller has never been arrested for, nor charged with any offense as a result” of the incident.

Taylor’s death sparked protests; jumping it into the national debate about police officers’ use of force against unarmed minorities.
