FBI links Carlsbad man to Wisconsin school shooting suspect

A 20-year-old Carlsbad man has been ordered to surrender his guns after authorities said he communicated with the teenage girl suspected of committing a fatal school shooting in Wisconsin, allegedly expressing his own plans to carry out a deadly attack against a government building.

Police and FBI agents went to the home of Alexander Paffendorf on Tuesday night to seize his guns and ammunition after a San Diego Superior Court judge approved a gun violence restraining order, according to documents obtained by NBC 7.

The restraining order said, in part: “During an FBI interview, Paffendorf admitted to the FBI agents that he told Rupnow that he would arm himself with explosives and a gun and that he would target a government building.”

Paffendorf was detained, but it was not clear if he was arrested.

The Carlsbad Police Department told NBC 7 on Wednesday night that “there is no threat to the Carlsbad community at this time.”

The FBI’s San Diego office declined to comment.

On Monday, 15-year-old Natalie “Samantha” Rupnow allegedly fatally shot a teacher and a student and wounded six other people at Abundant Life Christian School, in Madison, Wisconsin.

Rupnow was later found dead at the scene with what were believed to be self-inflicted gunshot wounds.
