A San Rafael woman accused of stabbing her mother to death this week made her initial court appearance Thursday as authorities reviewed why she was allowed to leave a police station after displaying a knife just hours before the slaying.
Olivia Lucia Beltran Pacheco, 55, was named Wednesday by the coroner's division of the Marin County Sheriff's Office. She was stabbed late Monday at an apartment complex on Cresta Way in north San Rafael.
