The Winter Haven Police Department said Ruby Bing was found shot to death at her mother's front door.

Police said Adele Bing, 52, had an argument with her boyfriend, James Lane, earlier in the day and allegedly hit him with a gun. Lane went to the hospital to be treated for his injuries when officers said they received a call about a shooting at Adele Bing's home.

Authorities said Ruby Bing went to visit her mother and knocked at her front door while holding her 4-month-old baby.

Police said Adele Bing was still upset about the argument she had with Lane and thought he was the person knocking.

Investigators said Adele Bing armed herself with a baseball bat and a handgun, and as she opened the door, she fired a shot, hitting her daughter in the upper chest.  The 4-month-old was not injured, but Ruby Bing died at the scene.

Police said Adele Bing charged with second-degree murder and child abuse without great bodily harm.

Bing was transported to the Polk County Jail.
