DALLAS (AP) - The former Dallas police officer who fatally shot an unarmed black man in his own home told a 911 dispatcher "I thought it was my apartment" nearly 20 times as she waited for emergency responders to arrive.

That's according to a 911 recording obtained by Dallas TV station WFAA . Amber Guyger, who is white, is charged in the September 2018 killing of Botham Jean. She has said she entered Jean's apartment, thinking it was her own, and fatally shot him.

Guyger can be heard apologizing to Jean, who was a 26-year-old native of St. Lucia. She also says: "I'm gonna lose my job."

WFAA hasn't said how it obtained the recording. The Dallas Police Department hasn't responded to Associated Press phone and email messages seeking verification of the recording.
