A Los Angeles man has been detained in connection with the fatal stabbing of his estranged wife at an Albertsons market in Santa Monica Aug. 21, police said.

The suspect, Kelvin Green, who was taken into custody Aug. 22, was being treated at a local hospital for an undisclosed medical illness and is expected to be booked with murder upon his release, Santa Monica police Sgt. Richard Lewis said.

Police were called at 3:24 p.m. Aug. 21 to the Albertsons at 3105 Wilshire Blvd., where a female employee was found with more than 20 stab wounds to the head and torso but was still conscious, Lewis said. The victim, identified as 46-year-old Christina Talley of Los Angeles, was transported in critical condition to a local hospital, where she was pronounced dead early Aug. 22, Lewis said.

Talley was working at a check-stand when she was approached from behind by a man and stabbed several times in the head, neck and upper torso with a knife, Lewis said. Following the attack, the suspect fled the location in a vehicle described as an older model gold Cadillac, police said.

Police initially identified Green as a person of interest, but during the subsequent investigation he was determined to be a suspect in the fatal stabbing, Lewis said.

Detectives gathered information on the possible whereabouts of Green at about 7:30 a.m. Aug. 22 and took him into custody at a family residence shortly thereafter, Lewis said.

Witnesses told police that the suspect had a brief verbal exchange with the victim and she was aware of the suspect’s presence prior to the attack, Lewis said. One customer tried to intervene but backed off when the suspect allegedly made a slashing motion, and other customers threw items at the suspect before he fled, Lewis said.

The investigation is ongoing but the police said the motive appears to be domestic related. Family members told police that Talley and Green were separated for at least a month and the victim had obtained a criminal protective order against her estranged husband, Lewis said.

Anyone with additional information regarding this case is asked to contact Det. Larios at (310) 458-8937, Sgt. Jacob at (310) 458-8460 or the Santa Monica Police Department (24 hours) at (310) 458-8495.
