A New Jersey man who planned to kidnap and kill a woman he met online and went on two dates with is headed to prison.

Federal prosecutors say 36-year-old Christopher Thieme received a 17 ½-year sentence Monday.

Authorities say the woman attempted to cut off contact with Thieme after two dates.

Prosecutors say Thieme then asked a friend for help to kidnap the woman. They say the friend called authorities, who set up a sting operation.

Investigators say Thieme told an undercover FBI agent that once the woman was kidnapped, he would empty her bank accounts and fraudulently sell off her home. He would then use those proceeds to pay for the kidnapping and murder.

Thieme, of Newton, pleaded guilty in June to attempted kidnapping and murder-for-hire.
