Many prayers tonight are with the lone survivor - a 12-year-old girl who survived a bullet to the head.
"He was looking at her when he shot her - she was looking at him," said family relative Joseph Simmons.
"Thankfully in the split second that mattered most, Eyewitness News is told that the terrified 12-year-old daughter flinched, and that may have saved her life. The bullet went in and out of her head without killing her.
Simmons says the bullet went through the soft part of her eye.
"Best kids you've ever seen in your life, I don't know how he could take away something like that," says the victims' relative, Wendell Warren.
Police report 34-year-old Jonathon Walker came home at 5:30 Saturday morning to his beautiful family in Brookville, Queens, then shot each one in the head - his 7-year-old daughter Kayla Walker, his 12-year-old daughter, the girls' mother Shantai Hale, and Hale's mother, 61-year-old Viola Warren. Miraculously the 12-year-old survived, and called 911.
"She IDs her father, Jonathon Walker as the shooter," said NYPD Chief of Detectives Robert Boyce.
Eyewitness News is told the father then took off in his SUV, drove about 6 miles away to a secluded area by JFK, then fatally shot himself in the head. With all of the bloodshed, there are no answers. Why would a father murder his family?
Walker, 6'6", 260 pounds, worked as a security guard and a bouncer. He had two arrests for minor issues and had legally obtained the 45 caliber handgun, which he used to wipe out three generations of one family.
Joseph Simmons says there were signs of domestic abuse, but doesn't know if Shantai had feared for her life.
"We think so, but none of us can say, because she wasn't talkative," he adds.
Eyewitness News has learned that the 12-year-old still has vision in her eyes, and that surgeons removed a part of her skull because of swelling in the brain.
