Christine Diane Himmel, 46

Christine Diane Himmel, also known as Christine McQueen, a 46-year-old white woman, died Saturday, April 8, after she was stabbed in the 18700 block of Vista Del Canon in Santa Clarita, according to Los Angeles County coroner’s records and the Los Angeles County Sheriff's Office.  

Himmel’s longtime girlfriend, Pamela Michelle Walker, called Himmel’s mother about 1 p.m. and told her she had killed her daughter, according to Los Angeles County Sheriff’s Sgt. Troy Ewing.

“She said, ‘Hey, I just stabbed and killed Christina. Can you get up here?’” Ewing said, 

Both Himmel and Walker, who had been a couple for nearly 15 years, had a history of mental illness, Ewing said. Walker allegedly had made untrue statements before and Himmel's mother was skeptical, he said. “So she initially didn’t believe her, and she didn’t act on her request,” Ewing said. 

But Walker went to the mother’s home in Toluca Lake about 5:30 p.m. and said again that she had killed her daughter, Ewing said. 

Walker’s clothes were bloody, he said, “and this time, she believed her.”

The mother called deputies, who forced their way into Himmel’s Santa Clarita home. They found her in a bedroom with multiple stab wounds, Ewing said. 

Himmel was pronounced dead at the scene at 6:02 p.m., according to coroner’s records.

Walker, a 34-year-old black woman, stayed at the home of Himmel's mother until she was arrested on suspicion of murder and booked into jail, where she is being held in lieu of $2 million bail, according to jail records. 

On April 11, Walker was charged with murder and pleaded not guilty, according to court records. Her next hearing is set for April 26, in Department S of the North Valley Superior Court in San Fernando.
