One of two charges has been dropped in the case against Topeka Dr. John Toth.
Dr. Toth is charged with the death of his patient Beverly Wunder, 47, after giving her and another woman treatments for Lyme disease, which they never had.
Toth is charged with the second-degree murder of Wunder.
A charge of Aggravated Battery for bodily harm to the other woman was dropped Friday.
The Board of Healing Arts suspended Toth's license in 2005.
It all started when the two women ended up in the hospital. Both were patients of Dr. John Toth, both receiving the same treatment for Lyme Disease.
He is accused of treating them with injections of bismacine, which contains a chemical that can be poisonous.
