A report released by the Inspector General on Monday adds new details about high ranking employees in Chicago’s Water Department sending racist emails.

According to the report, one Department of Water Management supervisor sent an email to coworkers joking about a “Chicago Safari adventure.”

Using a taxpayer-funded email account, the employee referred to black residents as animals and listed murder scenes on the South and West sides as attractions.

A different supervisor sent an email using a slur for Muslims, and another suggesting people should throw grenades at a black politician.

Both resigned when faced with termination, according to the report.

Chicago’s Inspector General said other water department employees are being investigated, but that investigation is hampered because the city’s law department won’t allow the Inspector General’s office full access to city emails.

The city’s law department did not immediately respond to a request for comment.
