The Texas Rangers investigated and charged her with manslaughter.

Dallas County District Attorney Faith Johnson convened a grand jury, and Guyger has been indicted for murder:

A former Dallas police officer who walked into an unarmed man’s apartment on Sept. 6 and shot him while wearing her police uniform has been indicted on a charge of murder.

The Dallas County grand jury began hearing the case against Amber Guyger, 30, on Monday. Guyger was originally charged with manslaughter in the shooting death of 26-year-old Botham Shem Jean. She was released from jail on a $300,000 bond about an hour after turning herself in.

District Attorney Faith Johnson said that by 3 p.m., Guyger had turned herself back in on the murder charge. Her bond was transferred and she has been released.

Asked why the grand jury indicted Guyger on a murder charge, Johnson said, “We presented the evidence and explained the law.” She added that the law prohibits her from talking about the evidence presented to the grand jury.

She said her office had a “very spirited conversation” with the Texas Rangers, the lead investigators in the case, back in September.

“They chose to file this case as manslaughter,” she said. “We did our own investigation.”

A district attorney who doesn’t spend their time covering up for the police is remarkable.

The fact that she is a Republican makes it it even more remarkable.

She was turfed out in recent elections, but her replacement, Democrat John Creuzot ran on criminal justice reform, so my guess is that he will continue to pursue this case with vigor.
