"The bear is being killed by the girl."

Translation: Bjørnen bliver dræbt af pigen.

He raised her and then she killed him?! :'( Poor bear!

[SentientHuman]

Yeah, the dark story of the girl and the bear runs through the Danish section of Duo...

[Mr.Keko]

This is to teach you not to trust the girl: the bear may steal your wheels but the girl is going to kill you.

According to Google, “dræbes” is also correct. Are there any rules/consideration regarding when to use “bliver” or the -s form of the passive? Or are they truly interchangeable?
