Seattle police are trying to determine why a man climbed a 200-foot electrical tower where he apparently electrocuted himself on a 120,000-volt line.

Witnesses reported seeing a flash of crackling sparks before 1 a.m. Friday and the man falling.

He landed on a platform at about the 150-foot level where the body was recovered by a fire department technical team after Seattle City Light turned off the electricity.

City Light spokesman Peter Clarke says the man could have climbed up the metal lattice of a tower leg and the utility will be reviewing that to make it less easy.
