Court documents say a Columbia man who used Bitcoins in an attempt to buy a highly toxic chemical through the mail may have been trying to kill a woman who rejected him.

The Columbia Daily Tribune reports that 44-year-old Jason William Siesser made an initial appearance Friday on a single charge of attempting to purchase toxic poison to use as a chemical weapon.

Tim Garrison, U.S. Attorney for the Western District of Missouri, said in a news release that there are no allegations that a public attack was planned. He says federal agents executed a search warrant after observing Siesser sign for a package, which contained an inert substance.

An FBI agent wrote in the affidavit that a target was identified in writings found in the home.
