Mom 'used her last breath' to save daughter by hiding her in the toilet as marine father shoots her dead

A mother saved her six-month-old baby with her 'last breath,' sheltering the infant in the toilet after her boyfriend shot her in the head and turned the gun on himself. Jessica Arrendale, 33 (pictured with her baby), was found dead of a gunshot wound to the head along with Antoine Davis (right), 30, who police believe shot himself and Arrendale in a murder-suicide in an Atlanta suburb.

Police had surrounded Arrendale's townhouse. When they finally entered the home, they found the baby safe inside and rushed her to the hospital to treat her for hypothermia.

Officers arrived at the home in Smyrna in the early morning hours Sunday, responding to a call that there was someone in the home armed with a gun. 

Arrendale's mother, Teresa Ionniello, told WSB Radio that Arrendale and Davis were together the night that Davis became 'belligerently drunk and abusive,' an episode that sadly had happened many times before in their relationship.

Davis chased Arrendale up to the third floor of her home, where Arrendale picked up a baseball bat to defend herself, according to Ionniello, though Davis overpowered her and struck her with the bat.

Arrendale then barricaded herself in the bathroom with their six-month-old, Cobie. Davis went to get his firearm, an assault rifle, from the closet, and it was around this time that police arrived at the home..

Davis's ex-wife Tamaira Chesley described Davis in kind terms, saying that lately he had been struggling with depression and mentioning a custody dispute he had with Arrendale

The Atlanta Journal-Constitution reports that police evacuated nearby homes as a precaution and attempted to make contact with the armed man inside.

When officers made the decision to breach the doors around 1:30 p.m., they found the bodies of Arrendale and Davis, both killed by gunshot wounds to the head, Davis's reportedly self-inflicted.

Cobie was found in the toilet bowl, covered by her mother's body but safe and alive. SWAT officers rushed her to the hospital to treat her for hypothermia. "She had pure will. She wanted that baby to live,' Ionniello said of her daughter. 'Her last breath was saving the child.
