A Wisconsin man is accused of trying to buy a lethal dose of a radioactive substance on the Internet to try and kill someone.

Justin Tolomeo, Special Agent in Charge of the Milwaukee Division of the Federal Bureau of Investigation said in a news release Jeremy Ryan, 30, of the Town of Madison has been charged with attempted possession of radioactive material with intent to cause death.

Ryan allegedly attempted to buy the lethal dose in March and October of 2018. He was arrested on Tuesday.

Ryan, who was dubbed “Segway Boy” faced multiple felony drug charges in 2016. He got the nickname after he was seen riding a Segway around the state capitol in 2011 taunting Republican lawmakers.

He also attempted a congressional run against Paul Ryan in 2012.

The attempted possession of radioactive material with intent to cause death charge carries a maximum term of life in prison.

The case is being prosecuted by the U.S. Attorney's Office in Wisconsin’s Western District.
