Newton Police investigating the Thursday death of 62-year-old Richard Schroeder, a retired U.S. marshal of Newton, now believe the death was from natural causes, based on preliminary autopsy reports.

At about 9 p.m. Thursday, Schroeder's wife arrived home in the 1000 block of Boyd Avenue to find her husband lying in the driveway with head injuries, according to the Newton Police Department. She called 911, and Newton EMS transported Schroeder to Newton Medical Center, where he was pronounced dead.

While the death initially was investigated as "very suspicious" by the NPD, all indications are it was from natural causes, according to Sgt. Craig Dunlavy with the NPD.

Schroeder had been involved with protecting late-term abortion provider Dr. George Tiller, first as a marshal and then as a private detective, as well as being involved in other high-profile cases. For a complete story, see Saturday's Kansan.
