The death of a Con Edison worker in Brooklyn last month was caused by a short circuit in a 120-volt cable, according to an investigation by the utility.

George Dillman, 26, was killed Oct. 9 while splicing cable about 10 feet underground in East New York. The utility says the cable's short circuit caused the explosion that killed Dillman and that no combustible or flammable materials were found in the air that could have led to the blast.

Con Ed also found that Dillman's partner, Craig Penney, followed proper procedure after the explosion and did all he could to get his partner out the manhole.
