From The San Antonio Express-News: Unfounded rumors about threats of mass shootings at schools the San Antonio, Texas, area have prompted thousands of students to stay home in recent weeks, which has cost local school systems more than $80,000 in state funding. The most widely spread rumor alleged that teen members of a “wolf pack” were plotting Columbine-style rampages in high schools. Another version claimed that pack members, who sometimes don a wolf tail and dog collar, had a suicide pact. According to that rumor, one member planned to commit suicide per week. Lately, schools' absentee rates have returned to normal because districts worked to investigate the claims and calm anxious parents and students.
