A Missouri man is heading to federal prison for trying to buy a chemical weapon. The Justice Department says Jason Siesser was sentenced to 12 years without parole after admitting he attempted to buy a highly toxic chemical in 2018. He tried acquiring the substances using Bitcoin on the dark web. The Department explained the amount of chemicals he ordered was enough to kill hundreds of people. Prosecutors noted writings were found in the 46-year-old's home that signaled his heartache and anger over a breakup, and he wanted the person who caused it to die.
