Received an unexpected cashiers check for over $2K from another state - is this some scam?
This is so very much a scam.  The accepted answer already tells you the basics of it.  In addition to the cheque being fake, there is also the possibility that the cheque is a legitimate cheque but has been stolen (or swindled off) from somebody else.  In that case, the delay with which the cashing of the cheque will blow up can be considerably longer than the accepted answer states since it depends on the other victim noticing and reporting the fraudulent transfer. The end result is the same: you are not going to be allowed to keep the money. Report this to both your sister's bank as well as her local police.  Nothing good can come off this.
