Well, the first card could just be happenstance. There's probably lots of ephemera left from the victim's life at home, or just blowing along the ground if it happens outside.

Second card? Hmm, strange coincidence, the investigator might think, if s/he's the same one who attended the previous death.

Third card - hey, wait a minute, what's going on here...

Fourth card - even if no one's officially connected the cases in the media, I could see an investigator going to someone known to the police as a psychic (even if they don't believe it officially) to ask about what these cards mean, and if they seem to be leaving a message.
