According to the Los Angeles Police Department, the suspect was arrested by homicide detectives late Wednesday night.
The victim's mother told Eyewitness News police are still searching for other people spotted leaving the scene on the night Jasmine Preciado was killed.
Three people, two women and one man, were sought in the killing of the 22-year-old, who was found with stab wounds near Windward and Pacific avenues on Nov. 21.
The deadly attack was captured on surveillance video. In the footage, a scuffle appears to start on the left side of the screen. Then a woman runs onto the sidewalk and turns, appearing to hold a knife in her left hand.
Preciado, the mother of a 3-year-old girl, was pregnant with her second child.
