*(Via MSN News) – In the quiet of a pre-dawn Saturday on a dead-end street, a father came home and shot his family in their heads, leaving women in three generations dead and a wounded 12-year-old girl calling 911, police said.

“What I did, I cannot come back from,” Jonathon Walker (pictured)  told his brother by phone soon afterward, police said. And Walker did not come back — police said he killed himself in his car on a desolate street a few miles away, ending a burst of violence that stunned relatives who said the family hadn’t shown signs of trouble.

The 34-year-old security guard had killed his 7-year-old daughter, Kayla Walker; his 31-year-old girlfriend, Shantai Hale; and Hale’s mother, Viola Warren, 62. His and Hale’s older daughter, whom a relative identified as Christina Walker, was hospitalized in stable condition, police said.
