A 20-year-old man has been detained by authorities in Carlsbad, California, in connection with the deadly school shooting in Madison, Wisconsin.
According to a gun-violence restaining order issued Tuesday and obtained by CBS 8 in San Diego, FBI agents detained Alexander Paffendorf after discovering that Paffendorf had been texting 15-year-old Natalie Rupnow around the time of the shooting at the Abundant Life Christian School on Monday, where she opened fire, killing a student and a teacher. She took her own life, and two students are still hospitalized in critical condition.
