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.

The Detroit Red Wings lost the services of one of their top-pair defenseman in the first period Wednesday.

Simon Edvinsson did not return after the first period because of what the team called an upper-body injury. The Red Wings announced the move on social media after the first period.

Edvinsson only played 5:36 in the first period. That forced the coaching to scramble the other pairings, and Ben Chiarot instead was out on the ice with Edvinsson’s usual partner, Moritz Seider.

Edvinsson, 21, is in his first full season with the Wings, although having played 25 games over the previous two seasons, he is not considered a rookie. The 6-foot-6 Swede quickly worked his way up to the top pairing, where he and Seider (6 feet 3) give the Wings a formidable pairing with enormous reach.

Edvinsson has also helped contribute offensively, with three goals and 10 assists, in 30 games.

It was not immediately clear how or when Edvinsson got injured in the game Wednesday vs. the Flyers.

MILWAUKEE – Prosecutors are reviewing whether to charge a 12-year-old boy with shooting and killing a man. It happened several days ago – and on Wednesday, Dec. 18, the boy was back in court via video. 

On Monday, a Milwaukee County judge ordered a 48-hour hold on the boy in the homicide investigation as the state worked to put its case together. That hold is now expired, but the boy will remain in custody until at least Thursday afternoon.

Homicide investigation near 51st and Locust, Milwaukee

About an hour after the shooting, police arrested a 12-year-old boy at a home near 52nd and Garfield in connection with the shooting. 

On Monday, the boy’s defense attorney said while brief, the initial police reports indicated the case was of self-defense. 

State law requires that when children 10 or older are charged with homicide, adult court has original jurisdiction.

The boy also appeared Wednesday afternoon on a separate juvenile petition that has been open since June. In that case, if the adult hold expires, the boy will be released to his mother.
