Three Charged in Fatal S.F. Explosion and Fire
Federal authorities Thursday charged two men and a woman with illegally manufacturing fireworks that caused an explosion and fire at an industrial park, killing at least eight people.
U.S. Atty. Joseph Russoniello said Wayne Quan, 28, and his sister, Laureen Quan, 25, were arrested by federal agents, and Steven Leong, 28, turned himself in.
All were arraigned before U.S. Magistrate Claudia Wilken, and Leong was freed on $50,000 bail.
A fourth suspected member of the operation, Thomas Cuyos, 28, was killed in the April 4 blast.
They allegedly operated a clandestine fireworks factory at Bay View Industrial Park on the southeastern rim of the city. The huge warehouse containing a maze of tiny businesses, as well as the fireworks operation, blew up and triggered a huge fire.
Nolan Florita, 26, who is missing and presumed dead, was helping Cuyos in the Bay View operation at the time of the explosion, according to court statements.
