A man accused of robbing a convenience store and killing the cashier 32 years ago is now in police custody. A grand jury has indicted Antonio Wabol, 52, on a charge of aggravated murder with a firearm. Myong Su Cho, 29, was working behind the counter at a Plaid Pantry near Portland State University on January 18th, 1980. Police say, after the cold case was reopened last year, evidence sent to the state crime lab led to the identification of Wabol as the suspect. Wabol is scheduled to be arraigned today.
