A 52-year-old Los Angeles man has been charged with murder for allegedly fatally stabbing his estranged wife while she was working at a Santa Monica supermarket.

The Los Angeles County District Attorney’s Office charged Kelvin Green Aug. 26 with one count of murder and one count of assault with a deadly weapon in connection with the killing of Christina Talley, 46, said Deputy District Attorney Linda Loftfield.

The complaint alleges a prior felony conviction for robbery in 1985 and that Green personally used a deadly weapon, Lotfield said.

Green is accused of stabbing Talley multiple times while she was working at a checkout counter at an Albertsons market at 3105 Wilshire Blvd. in Santa Monica Aug. 21, police said. Talley died the following day at a local hospital.

Green also allegedly assaulted a Good Samaritan, who tried to help stop the attack inside the store, though the customer was not injured, prosecutors said.

Santa Monica police took Green into custody Aug. 22 at a family residence and he was initially treated at a local hospital for an undisclosed medical illness, police said.

Green, who was placed under arrest Aug. 24, appeared at the Superior Court Airport Courthouse for an arraignment Aug. 26 but the hearing was continued to Sept. 8, district attorney spokeswoman Jane Robison said.

He remains in custody on $1 million bail, Robison said.

If convicted, Green faces up to life in prison.
