KANSAS CITY (AP) – A special prosecutor who was reviewing the case of a handcuffed Iowa man who drowned in the Lake of the Ozarks has recused herself, citing that it would be a conflict if she stayed on the case.

The Kansas City Star reports that Osage County Prosecutor Amanda Grellner filed a motion Wednesday to take herself off the case. Grellner said that she stepped down because a conflict had recently developed in the additional investigation that is being performed.

She did not reveal the nature of the conflict.

A new prosecutor will be appointed.

Brandon Ellingson, who drowned in May 2014 while in custody of a Missouri Highway Patrol trooper. Grellner had initially decided to not file charges after jurors at a coroner’s inquest found the death to be accidental.

The prosecutor reopened the case in January after receiving new information.
