Killer Dallas cop Amber Guyger was sentenced Wednesday to 10 years in prison for fatally shooting her unarmed black neighbor after she mistakenly entered his apartment.

The jury sentence came after just two hours of deliberations — and one day after Guyger, 31, was convicted of murder in Dallas County court for the 26-year-old’s Sept. 6, 2018 shooting death.

Jean’s younger brother, Brandt, shared a lengthy courtroom embrace with his sibling’s killer after the sentence was handed down.

“I don’t even want you to go to jail. I want the best for you because I know that’s exactly what Botham would do,” Brandt said in a victim-impact statement after the sentencing. “I don’t know if this is possible but can I give you a hug? Please?”

The defense argued that the ex-cop feared Jean was an intruder when she barged into his unlocked apartment, mistaking it for of her own pad one floor below.

“We know by the verdict that it was an unreasonable mistake, but it was still a mistake,” defense attorney Toby Shook said Wednesday in closing statements. “She didn’t go there trying to kill him. It was the last thing on her mind.”

Prosecutors, however, claimed that her defense was “absurd” and questioned how she missed the signs that she was in the wrong apartment.

Guyger faced a sentence of 5 to 99 years in prison for the murder charge. Before the guilty verdict was handed down, she elected for the jury to decide her sentence.

The prosecution asked the jury hand the fired cop no less than a 28-year sentence.

“This is not a five, 10 or 15-year case. Botham didn’t provoke his own death,” Prosector LaQuita Long said.
