PITTSBURGH -- A Pittsburgh-area woman already accused of murdering an FBI agent who came to arrest her husband on drug charges was arraigned on drug trafficking and weapons violations on Thursday.

Investigators said Christina Korbe, 40, has been trafficking cocaine since 1990.

Korbe pled not guilty to the new charges.

Korbe has been jailed since Nov. 19, when she shot and killed agent Samuel Hicks, who was the first of several officers to enter her Glenshaw home in a pre-dawn raid. Her attorneys have portrayed Korbe as a soccer mom who shot Hicks only because she feared he was an intruder endangering her children.
