My wife worked at the power company in the trouble center, analyzing outages and directing crews to fix the problem.
One night she had a large outage caused when a substation went down. Usually, this was caused by a critter (raccoon, opossum, or squirrel) that got inside and landed on the wrong thing. Crews would go in, clean out the remains - usually flash fried - and the power would be restored.
On this night she got a call back from the crew requesting police. It seems two guys had broken into the substation to steal copper but didn't check to see if it carried a few thousand volts first. It took authorities a while to identify them through dental records.
It seems it's not an isolated case. Thieves are zapping themselves all over at substations. Just Google it.
