In this case, it struck rather more tragically than usual. Miss D. sent me a link to this story.
Bristol Tennessee Police Department Officer Chester Emery, 47, suffered multiple injuries from a single round fired from the Ruger MK II .22-caliber semiautomatic handgun that a woman identified as his girlfriend, Kelly Crandell, 46, was shooting.
The round passed through Emery’s wrist and struck him in the chest. He was flown to Johnson City Medical Center for treatment. As of 9:20 p.m., Emery was listed in stable condition.
Emery, who is also an instructor at the shooting range, told an SCSO deputy the shooting was accidental. He said it happened when a piece of hot brass went down the front of Crandell’s shirt as she was shooting down range.
Crandell told investigators she “jerked” when the hot brass went down her shirt, accidentally discharging the pistol.

I've seen a cartridge case go into an open shirt on three occasions - and each time it led to some interesting reactions. Low-cut T-shirts or open-neck shirts are not, repeat, NOT the right clothing for a shooting range! A hot cartridge case, ejected by a pistol or rifle, is quite capable of inflicting a second- or third-degree burn on soft, tender skin. The picture below shows the burn produced by a .22LR cartridge case (the same type used by Ms. Crandell) on a shooter's neck. The burn mark is circled in red. (I'm obliged to reader Mark L. for sending me the image.)
Frankly, I blame Officer Emery for not warning his girlfriend about the possible consequences of wearing clothing like that at a shooting range. On the other hand, I daresay he's now a whole lot more likely to remember to do so in future!
