In October 2005, the city gained national media attention once again when 19-year-old resident William Freund donned a cape and mask, and murdered two of his neighbors, 22-year-old Christina Smith and her father Vernon, before killing himself. Freund had Asperger syndrome and posted on an Internet message board for people with the disorder, in which he talked of suicide and acts of violence. On November 17, 2006, the family of the two victims sued Freund's parents for "wrongful death and emotional distress." Freund lived with his parents at the time of the shooting and had a history of mental disorders including Asperger syndrome and attention deficit disorder, but the court ruled that Freund's parents were not liable for his actions because he was an adult at the time and the attacks were unforeseen.
In September 2006, Charles Salter, the principal of Aliso Niguel High School, Aliso Viejo's high school, gained widespread media attention when he banned all school dances until further notice.

At the end of the month, Salter stood his ground and cancelled the school's annual Homecoming Dance, which gained both Salter and the school notoriety. A story on the school was featured on the national television program, Geraldo at Large and the BBC also covered the dance ban. In late November, it was announced that the dances would return to the school, but under new rules that banned "freak dancing".
