A 26-year-old Renton woman pleaded not guilty on Thursday to assault and robbery charges in connection with stabbing and injuring a 64-year-old Kent man at his home.

Abbie M. Rupnick, who was arrested by Kent and Auburn police on Aug. 15 at the Muckleshoot Casino in Auburn, entered not guilty pleas in King County Superior Court in Kent to first-degree assault, second-degree assault and first-degree robbery charges for the July 22 attack at a East Hill home.

Rupnick remains in custody at the county jail with bail set at $500,000. She is scheduled to return to court on Sept. 1 when a trial date could be set or attorneys could ask for more time to prepare the case.

According to court documents, Rupnick allegedly helped Michael Antony Santos, 32, of Kent, rob and attack a Kent man who knew Rupnick but didn’t know Santos. Santos also faces first-degree assault, second-degree assault and first-degree robbery charges. He has pleaded not guilty and remains in jail with bail set at $500,000. His trial date has yet to be set.

After a roommate of the 64-year-old man let Santos and Rupnick into the house, they reportedly attacked the man. Santos allegedly accused the man of being a child molester and a snitch. The man suffered stab wounds to his groin, back and legs. He was released in mid-August from Harborview Medical Center in Seattle, according to a hospital spokeswoman.

Kent Police issued media releases to help find Santos and Rupnick after the attack. Kent Police arrested Santos on July 28 in Kent.
