St. Louis County's top elected official is asking the Missouri Attorney General's office to take over the case of a police officer who shot an unarmed teenager, a shooting that spurred international attention. But Attorney General Chris Koster has no plans to do so.

Koster on Friday confirmed that St. Louis County Executive Charlie Dooley asked that the county's prosecutor, Bob McCulloch, be removed. Dooley spokeswoman Pat Washington told the St. Louis Post-Dispatch that Dooley believes McCulloch is biased and shouldn't handle the case. Messages left for Washington by The Associated Press were not returned.

Koster says that except in very rare circumstances, the governor and the attorney general have no authority to remove an elected county prosecutor or transfer a case.
