Members of the Osage County Sheriff's Office set up a makeshift home base in Carbondale Monday, after a mushroom hunter found human remains in the area Saturday evening. The Osage County Sheriff's Office sent a press release Tuesday stating that the search had concluded. Additional bones were discovered, but it's not clear if they are human or animal.

Law enforcement officers have concluded their search of an area where human remains were discovered Saturday night near Carbondale, about 15 miles south of Topeka in Osage County.

The Osage County Sheriff’s Office sent a news release to media outlets Tuesday afternoon stating that “numerous bones and bone fragments were located” during the search.

Those bones and fragments have been sent to the First Call Morgue in Kansas City, Kan., “to determine whether they are human or animal,” according to the release. Additional DNA testing on the remains found Saturday “could take several months.”

On Saturday evening, a mushroom hunter discovered the human remains on 118th Court, just off Wanamaker Road, in Carbondale, a town with a population around 1,400. Osage County Sheriff Laurie Dunn has not yet disclosed more specifics about what was found.

Other news services, including The Associated Press, have reported that a skull was found.

Dunn said the nature of the case — whether it’s a possible homicide, suicide or death by natural causes — remains unclear.

In addition to Osage County law enforcement, Dunn said law enforcement officers from the Northeast Kansas “M-Squad,” comprised of representatives from numerous law enforcement agencies including the Douglas County Sheriff’s Office, assisted in the search.
