It's a moment very rare in the annals of crime history: A man hugging the killer of his own brother in the courtroom where she was convicted, wishing her the best.

That's the scene that played out in a Dallas courtroom Wednesday. In the moments following the sentencing of Amber Guyger, the former Dallas police officer who shot and killed a black neighbor after she accidentally walked into his apartment, the victim's brother had forgiveness in his heart.

Botham Jean was killed while eating ice cream in his own apartment, after Guyger mistakenly opened the door to his apartment and mistook him for an intruder. But his younger brother, Brandt Jean, didn't wish Guyger any ill will on Wednesday.

In fact, he wished Guyger nothing but the best and, holding back tears, he asked the presiding judge if he could hug the woman convicted of murder in the killing of his brother. Guyger, 31, was sentenced to 10 years in prison.

"I don't know if this is possible," the 18-year-old said in a video of the moment posted by WFAA-TV's Mike Leslie, "but can I give her a hug, please? Please?"

After a pause, Judge Tammy Kemp said yes.

Guyger and Brandt Jean embraced in the courtroom for nearly a minute. Kemp also hugged Guyger before she was led from the courtroom.

"If you truly are sorry, I know… I can speak for myself, I forgive you," he said before the hug. "And I know if you go to God and ask him, he will forgive you.

"Again, I'm speaking for myself, not even on behalf of my family, but I love you, just like anyone else. I'm not going to say I hope you rot and die just like my brother did, but I, personally, want the best for you.

Sobs were audible throughout the courtroom as the two hugged and Kemp could be seen wiping tears away.

"I wasn't going to ever say this in front of my family or anyone, but 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 want you to do. And the best would be, give your life to Christ. I'm going to say anything else.

"I think giving your life to Christ would be the best thing that Botham would want you to do."
