FBI Investigation Uncovers Carlsbad Man, 20, Allegedly Plotted Attack with 15-Year-Old Madison Shooting Suspect — Details
The restraining order, which CBS 8 obtained, detailed an alarming admission made by Paffendorf during an FBI interview, where he confessed to proposing an attack involving explosives and firearms.

Messages exchanged between Paffendorf and Rupnow, reviewed by federal agents, further substantiated these claims. The swift judicial response came late Tuesday evening, December 17, with a San Diego Superior Court judge approving the order at 8:51 p.m.
Shortly after, Paffendorf’s Carlsbad residence became the site of a significant police operation. One of Paffendorf’s neighbors, Alex Gallegos, reported seeing about 15 police officers with “full guns out all over the street.” He also mentioned that officers carried out a “black gun box” from the property.

While the FBI has deferred comments to the Madison Police Department, CBS 8 has noted that their report on the story will be updated as more information becomes available.
The protective order against Paffendorf came just two days after Rupnow’s deadly attack in Madison, where she killed two individuals and injured six others, two of whom remained hospitalized Wednesday, before taking her own life.

One victim was a dedicated teacher and the other was a promising ninth grader. They both leave behind legacies of love, talent, and devotion that have deeply impacted their school community.
Known for her compassionate nature and her ability to connect with students, West was described by seventh grader Angel Brube as “kind and caring” and an excellent communicator.
Sophomore Mackynzie Wilson, who saw West just hours before the tragedy, recalled her teacher’s infectious enthusiasm for life, and her deep love for her daughters, whose futures she was very excited about.
“She would have done anything for them… I just wish I could’ve gone back and given her a hug,” shared Wilson. West’s demise has left a palpable void in the hearts of those who knew her.
Her obituary highlighted that she was an “avid reader” who cherished creating and expressing herself through art. According to CNN and the late student’s online obituary, there will be a funeral service for Vergara in Madison this Saturday (December 21), followed by her burial at Roselawn Memorial Park.

As reported by The Associated Press (AP), Madison Police Chief Shon Barnes revealed that investigators were working to understand the reasons behind the attack.
“Identifying a motive is our top priority, but at this time it appears that the motive is a combination of factors,” he said. Reports state that the shooter used a handgun in the attack, and police are continuing their investigation to determine how Rupnow obtained the weapon.

“We also want to look at if the parents may have been negligent. And that’s a question that we’ll have to answer with our district attorney’s office. But at this time, that does not appear to be the case,” disclosed the police chief.
Additionally, investigators believe Rupnow was already inside the school when the attack began and have confirmed that no security breach occurred.

Regarding the matter of the victims, when Barnes was asked if Rupnow deliberately targeted her victims, he said, “We don’t know if there would be a reason to target a (substitute) teacher, in this case, who doesn’t have significant ties to the school.”
