LABELLE, Fla.- The LaBelle man at the center of a homemade poison plot admitted to making the deadly concoction today.

Jesse Korff, 19, pled guilty to making and selling the potentially deadly toxins ricin and abrin.

Federal authorities say Korff admitted to making the deadly poisons in his LaBelle home. Korff says he was selling ricin and abrin for use as weapons. He was also conspiring to kill a woman in the United Kingdom.

Today, Korff pled guilty in federal court to five counts of developing, producing, transferring and possessing toxins, five counts of smuggling toxins and one count of conspiring to kill a person in a foreign country.

Korff was arrested last January, following a joint investigation by US Immigration and Customs Enforcement, Homeland Security Investigations and the FBI.

Korff could face life in prison.

WINK News exclusively spoke to Korff's sister over the phone right after she learned her brother plead guilty.

"It is kind of shocking, I can't believe that anyone would want to do something like that," said Nancy Renaldi Hurtado.

"Whatever kind of punishment that they give him, he deserves every bit of it. I don't agree with whatever he did," said Renaldi Hurtado.
