Winter Haven, Florida, woman Adele Bing shot and killed her daughter in a deadly mistake. Bing thought the person at the door was her boyfriend, with whom she had just had a serious fight.

"How could I look my grandkids in their face and say I killed their mother?" Bing told police when they arrived at the scene. "Y'all can lock me away for good."

Bing's 25-year-old daughter, Ruby Bing, was coming to visit with her 4-month-old baby the night of Nov. 26, CNN reported. Adele Bing, 52, had just had a "heated argument" with her boyfriend, James Lane.

Police said she came to the door with "a baseball bat in her left hand and a .22-caliber pistol in her right hand," intending to kill Lane, 39, who reportedly told her he planned to kill her. Police were actually interviewing Lane at the time, who was in the emergency room with a head injury caused by Bing, who had hit him with a gun.

Bing shot her daughter in the chest. She died at the scene. The baby was unharmed.

Witnesses said they heard the shot and saw Bing holding her daughter in her arms and saying, "Baby girl, don't die."

Tachelle Kemp, Ruby Bing's aunt, said it was a tragic mistake, according to Bay 9 News.

"I knew from the very beginning when it was her mom that shot her, that it truly was an accident," Kemp said. "She didn't intend for her daughter to be on the other side of that door."

Bing now faces second-degree murder charges and child abuse without great bodily harm, CBS reported.

Bing called the episode "a f--ked up accident."
