DALLAS (CBSNEWS.COM) — 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, according to a 911 recording obtained by a Dallas TV station.

“I’m an off-duty officer. I thought I was in my apartment and I shot a guy thinking he was, thinking it was my apartment,” Amber Guyger said in the recording obtained by WFAA. She later says, “I’m f—d. Oh my God. I’m sorry.”
