Hey, I’m a born & bred Detroiter and I’m not sure what you’re referring to by “The Detroit major mass-murder”.

Google wasn’t helpful, but I would love to know more; can you expand on what event(s?) you’re alluding to?

They probably meant "murderer", not "murder". First search using that instead resulted in https://en.wikipedia.org/wiki/Hazelwood_massacre

He‘s German, and murderer is Mörder in our language, and pronounced like murder.

It‘s a mistake I make every now and then, as well.
