Doesn't a city agreeing to pay a civil wrongful death suit before a police officer is tried taint that officer's criminal trial?

Officer Jason Van Dyke is going to seek a change of venue because of inflammatory statements made by Chicago Mayor Rahm Emanuel regarding the death of Laquan McDonald.

How is announcing that the city has already paid the McDonald family $5,000,000 without a lawsuit any less prejudicial? Doesn’t it seem like the criminal case should precede the civil?

Hasn’t the city of Chicago, for all intents and purposes, declared Van Dyke guilty? How could they hope to find 12 jurors unaware of settlement?
