It is very easy to "spoof" an email address, so if someone is using the email address to target you, then they can make it appear as if it has come from that address when it actually has not.
You can find out more by viewing the full header information of the email. I can demonstrate this remotely if you wish.
I expect you will also have reported this to the authorities already too.
