DALLAS, TX (CBS/WBTW) – A former Dallas police officer has been found guilty of murder for killing an unarmed man in his apartment, which she claimed she thought was her own.

Former Dallas police officer Amber Guyger has been found guilty of murder in the shooting death of her 26-year-old neighbor Botham Jean.

The 31-year-old took the stand in her own defense, testifying about the night she says she mistakenly entered jean’s apartment- thinking it was her own.

“I pulled my gun out and I yelled at him, ‘let me see your hands,’” Guyger said.

Guyger had parked on the wrong level of her apartment complex. Jean lived one floor below her.

She told the jury she thought a burglar was inside her home.

Guyger says she lives with immense guilt every day.

“And I ask God for forgiveness. I hate myself every single day,” she said.

Prosecutors argued that Guyger was irresponsible and had been sexting with a married work partner leading up to the shooting.

“For her errors, for her omissions, Botham payed the ultimate price,” said Prosecutor Jason Hermus.
