JEFFERSON COUNTY, Alabama - Five-year-old Davieon Menefee is a tough little boy.

Shot in the back of the head and left for dead more than three weeks ago in a shooting that killed his mother and younger sister, Davieon is paralyzed but remembers everything that happened that horrific night, his grandmother said.

"He talks, he remembers everything, everybody,'' said Donna Bozeman. "He remembers every single detail of what happened. He said, 'Dad did it.'''

5-year-old Davieon Menefee was paralyzed and 3-year-old sister Gabby killed in March 19, 2013 shooting at their father's hand.

Authorities believe the shooting happened during the evening of March 19, sometime after 5 p.m. The three victims were found about 11:30 a.m. on March 20 by a family friend. Tiffany Bozeman, 30, and Gabrielle Menefee, 3, were pronounced dead on the scene. Davieon was airlifted to Children's of Alabama, where he remains. They were discovered inside their second-floor apartment at The Park at Rocky Ridge apartment complex in southern Jefferson County.

Earlier that day, Brandon Menefee - Bozeman's estranged boyfriend and the father of their two children - was found dead in Fairfield inside his car on Valley Road. An officer on routine patrol discovered Menefee's body when he stopped to see why the car was on the side of the roadway.

"It is still hard to understand how a dad could point a gun at a child and pull the trigger," said Jefferson County sheriff's Chief Deputy Randy Christian. "Those questions are left for the family to ponder, the father took the answers with him when he turned the gun on himself."

Donna Bozeman said it was the hardest moment of her life when she and other family members had to tell Davieon that his mother and baby sister were dead. "I had a knot in my throat and stomach,'' she said. "We had to tell him that they were dead and that his Dad is dead, too, and won't be back to hurt him."

"We had already been prepped by the psychologists about he might react, but he just sighed,'' Donna Bozeman said. "He was there and he already knew. He laid feet from his dead sister 14 to 17 hours. He already knew. He just needed confirmation."

Donna Bozeman said either she or her mother, Barbara Dotson, is always with Davieon at the hospital. Days are spent with almost constant visits from doctors, nurses and therapists of all kinds, such as speech and physical therapists.

Initially believed to be paralyzed from the neck down, Bozeman said there has been some movement in one of his arms. "Nothing is wrong with his brain,'' she said. "They're calling it a miracle. It's just unbelievable."

The grieving grandmother said she started grief counseling this week to help cope with the loss of her daughter and granddaughter. "Some minutes are easier than others,'' she said.

She is amazed at the resilience her grandson has shown. "Some nights are worse than others, and sometimes he'll just cry,'' she said. "But I think he's doing better than everyone else."

She said she doesn't know how long Davieon will be hospitalized, and what kind of care he will need once he is released. "He's got a long road ahead of him,'' she said.

Christian said despite that long road, he wouldn't bet against Davieon. "He has family that loves him very much and he has already shown us what a fighter he is,'' he said. "No doubt he survived for a reason and a purpose. Maybe he will grow up to be something really special. That's what we hope."
