"Yeah, painted smiley faces just show up at random at accidental drowning scenes"

the street name written in a distant location, too. it's a taunt.

"In Michigan, they found something strange among the group's
graffiti: the word 'Sinsiniwa.' They couldn't figure out what
it meant until a few months later when they arrived in
Dubuque, Iowa to investigate the death of Matt Kruziki.

His body was found on Sinsiniwa Avenue."

"Sinsiniwa" is way to much of a stretch to call coincidence.

“His body was found on Sinsiniwa Avenue.”

No that is the weird part. A body in Michigan was found then 2 weeks later in Iowa they found another body and that is where the Sinsinawa written.

Sinsinawa was the street in Michigan where the detectives think the body was put in the water.

Now that is another part that makes it weird. Reference at one murder scene to a location from the previous murder.
