50-year-old Chiu Chun Wong of San Lorenzo was killed yesterday after a 15-ton section of concrete came toppling down on him. Ouch. According to the Gate, the fatal workplace incident occurred at "J.C. Steel Fabrication at 220 Michelle Court shortly before 1 p.m. Tuesday." It seems that while Wong and another worker were putting a chain "around the bottom of the 20-foot-by-12-foot wall," the chuck of cement slipped, fell, and struck Wong, killing him instantly.

Although the fatal accident is believed to be an act of God, if you will, the city's building department, Cal/OSHA, and the SFPD are investigating the incident.
