A criminal investigation is ongoing into a Carlsbad man who allegedly communicated with the teenage girl who committed a deadly school shooting in Wisconsin last month, with authorities alleging in court documents that he expressed his own plans to carry out an armed attack against a government building. The law enforcement investigation has not resulted in criminal charges against 20-year-old Alexander Paffendorf, according to a deputy city attorney representing the Carlsbad Police Department at a Friday morning court hearing. No details regarding the ongoing investigation were disclosed, other than the attorney stating it is “not within the Carlsbad Police Department.” Friday’s hearing concerned a gun violence restraining order filed against Paffendorf, which led federal agents to detain him last month. The documents indicate firearms were “reported” and “physically searched for,” but do not state if any were actually seized. According to the restraining order, FBI agents discovered messages between Paffendorf and 15-year-old Natalie “Samantha” Rupnow, who fatally shot two people and injured six others at Abundant Life Christian School in Madison, Wis. The restraining order application alleges Paffendorf admitted to 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 appeared virtually at Friday’s hearing without legal representation. Though he stated he wished to go forward with the hearing, San Diego Superior Court Judge Devon Lomayesva said that with the results of the criminal investigation pending and because Paffendorf did not have an attorney, the hearing would be rescheduled to April “in (Paffendorf’s) best interest.” The gun violence restraining order will remain in effect in the meantime. At the conclusion of the hearing, Paffendorf told the judge, “In terms of just the whole thing, I would just like to apologize to the court. In terms of the gun violence protective order, whatever you feel is necessary and the Carlsbad Police Department feels is necessary, I’m willing to accept.”
