On September 14, 1929, she and other union members drove to a union meeting in Gastonia. They were met by an armed mob, and turned back. They had driven about five miles toward home when they were stopped by a car; armed men jumped out and began shooting. Wiggins was shot in the chest and killed. Her five children were sent to live in orphanages. Five Loray Mill employees were charged in Wiggins's murder but were acquitted after less than 30 minutes of deliberation in a trial in Charlotte in March 1930 despite the fact that the crime was committed in daylight and more than 50 people witnessed it. She was buried in the Bessemer City Cemetery on North 12th St. Hers is one of the biggest markers there, after being expanded by the A.F.L-C.I.O. in 1979 to include a marker inscribed, "She died carrying the torch of social justice."
