DREXEL, Mo. (AP) – The remains of at least two people were found in a rural Missouri yard, where the bodies of as many as six people could have been disposed, sheriff’s officials said Saturday.

Officials planed to resume the search early Sunday. Two sets of remans were found Friday on the three-arce wooded property northeast of Drexel in western Missouri, Cass County Sheriff’s Cpl. Kevin Tieman said.

“Right now we can say for sure two sets of remains, but we know that we are looking for as many as six (sets of remains),” Tieman said.

The deaths appeared to “drug-related” and were not “random acts,” Tieman said. He estimated the deaths occured over five years, and said the most recent remains were several months old.

The remains did not appear to be related to any ongoing investigations, he said. Deputies working an unrelated theft case received a tip about the remains, Tieman said.

One man was arrested Friday and taken into custody on unrelated charges. Tieman would not identify that man or say if he owned the property where the remains were discovered.

An anthropologist identified two separate sets of remains from the bone fragments, Tieman said.

The Kansas City Crime Lab and the Jackson County Medical Examiner were assisting.

Drexel, a town of about 1,100, is 55 miles south of Kansas City, a few miles from the Kansas border.
