Miguel Castaneda, 23, of Los Angeles, has been charged with murder as well as an allegation of using a knife as a deadly and dangerous weapon. Valentina Rosales, 23, of Pasadena, has been charged with accessory after the fact, the Los Angeles County District Attorney's Office said on Friday.
Investigators said Castaneda and the victim, 22-year-old Demetrio Tapia, got into an argument on social media several days before the incident. The two met to settle their dispute on Oct. 1 and got into a physical fight, which led to the stabbing, Pasadena police said.

If convicted as charged, Castaneda faces a possible maximum sentence of 27 years to life in state prison, and Rosales faces up to six years in prison, the DA's office said.
