On July 8, 2017, at 3:30 am, a homeless woman stabbed a man in the back for no apparent reason at the RABA bus terminal (1530 Yuba Street).

Michael David Terpinning, age 45, of Anderson was waiting for a ride from a friend in the area of California and Placer Street when a young woman approached him.  She was making nonsensical statements and claiming she had stolen property in her possession.  Mr. Terpinning said he told her he didn’t want anything to do with her, so he tried to walk away.  She began to follow him northbound on California Street while attempting to engage him in conversation.

Mr. Terpinning called the police to report her as a suspicious person who was following him.  As patrol officers began driving to his location, he called back to report that the woman had just stabbed him.  He updated his location by describing the RABA bus terminal.

Officer David Chapman arrived on the scene, where a Northstate security guard who witnessed the assault pointed out the suspect next to the terminal.  Mr. Terpinning was also at the scene.  He had blood on his shirt and told the officer he had just been stabbed in the back.

The suspect was holding a folding knife with a four-inch-long blade.  When the officer told her to drop the knife, she held the knife in front of her and told the officer she was going to “assault” someone.  Officer Chapman then deployed a Taser, which caused the suspect to fall to the ground and drop the knife.  She was then handcuffed and taken into custody.

An ambulance arrived at the scene and determined the stab wound on the victim’s back was likely very shallow, but he was transported to Mercy Emergency Room for further evaluation.

The victim and the security guard said the suspect became increasingly agitated as she followed Mr. Terpinning.  She stabbed him in the back as he was walking away from her.

The suspect was identified as Ruby Markest Acosta, age 25, a Redding transient.  She said she lost her temper because the victim asked her for a cigarette.  She admitted to using methamphetamine earlier in the evening.

Acosta was booked at the Shasta County Jail for Assault with a Deadly Weapon.
