From The Wichita Eagle today:
Authorities today are investigating the "very suspicious" death of a
Newton man identified by sources as Richard Schroeder, a retired former
U.S. marshal who has worked as a private investigator.
Richard Schroeder helped protect Dr. George Tiller – first as a U.S.
marshal and later as a private detective. Schroeder also got to know
Tiller on a personal level and thought of him as a friend.
