HALF MOON BAY – The shooting rampage that killed seven people at two mushroom farms this week wasn’t the first time a disgruntled farmworker opened fire at his coworkers at one of the farms.

Just seven months earlier, at the same California Terra Gardens farm off Highway 92 where the first four workers were killed Monday, a different farmworker was charged with trying to kill a co-manager, firing through the man’s trailer filled with family last July.
