PHYSICIAN, HEAL THYSELF: Mystery employee at EPA’s Denver office smears human waste and menstrual blood on the walls, clogs toilets and urinates on the floor.

‘A male supervisor … told her that management knows that it is a female on the [redacted] floor who has been wiping feces and menstrual blood on the walls (I’m really sorry, this is beyond gross) and that they are worried that her behavior is escalating,’ according to one email obtained by Greenwire.

Another email reported: ‘The incidents of urine on the seats and the floors are still occurring regularly in the women’s restrooms; however they are no longer limited to the 6th and 7th floors. Employees are now reporting incidents more frequently.’
