TOPEKA, Kan. (AP) — The head of the state's medical board and its general counsel announced their resignations Wednesday amid criticism that the agency mishandled cases, including that of a doctor accused of running a "pill mill" linked to 56 deaths.

Legislators have pressed for Executive Director Larry Buening to be fired, saying the Board of Healing Arts was too slow in investigating allegations of misconduct against physicians and too lax in its punishments.

The most recent was the case of Stephen Schneider, who is jailed without bond and faces 34 federal charges, including four counts of unlawful distribution of a controlled substance resulting in death. He has proclaimed his innocence.
