ANNAPOLIS, Md. — Prosecutors have dropped nine charges, including first-degree murder, against a Glen Burnie man in a fatal shooting during a botched robbery of a convenience store.

The Capital of Annapolis reports that prosecutors said Tuesday that they lacked physical evidence in the case against 19-year-old Shawn Johnson in the 2010 slaying of 48-year-old Youssef Attia at a 7-Eleven in Glen Burnie.

Earlier this month, Johnson was sentenced to 50 years in prison for his involvement in the armed robbery of Mr. Wings & Pizza that led to the death of 20-year-old Misael Flores.
