PONCA CITY, Okla. — An Oklahoma woman accused of plotting to kill her ex-husband in Israel has apologized for manufacturing the poison ricin as a judge sentenced her to more than three years in prison.

The Oklahoman reports that Danielle Dana Layman was sentenced Tuesday. The Ponca City woman pleaded guilty to unregistered possession of ricin in February.

The 38-year-old Layman was arrested last year after another woman told the FBI of the murder-for-hire plot. The informant says she met Layman after responding to a Craigslist ad for an overseas acting job. The woman said the job involved poisoning a taxi driver in Israel, later identified as Layman’s ex-husband.

Layman acknowledged making the toxin derived from castor beans, but insisted she never intended to use it, calling the alleged plot “an elaborate fantasy.”
