A 20-year-old Carlsbad, California, man has been ordered to surrender his guns after authorities said he communicated with the teenage girl who committed 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 San Diego.

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 has not been charged with any crime.
The FBI's San Diego office declined to comment.
Neighbors say they saw more than a dozen agents and officers descend on the home on Tuesday.
"A couple hours into it, towards the end, they're carrying out a big black box," Carlsbad resident Alex Gallegos said. "Looked like a gun case of some sort."
The protective order, which is in effect until Monday, says firearms were reported and search for, but it doesn't say what officers found — if anything at all.
Gallegos said Paffendorf kept to himself and hasn't been spotted in the neighborhood since.
"I've only seen him a few times," the neighbor said. "He's real quiet, just seen him walk to his car and back, said hello, that's about it."
On Monday, 15-year-old Natalie "Samantha" Rupnow 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.
